The Iran War

The United States, Israel and Iran were once strong allies, cooperating both economically and militarily.

During the 1960s and 1970s, Iran was a rising regional power, yet, internally, it was a tightly controlled state where political repression, social disruption and inequality were steadily eroding the state's legitimacy.

At the center of this transformation was Mohammad Reza Shah Pahlavi, who sought to turn Iran into a modern, industrialized state. After consolidating power in the aftermath of the U.S. and U.K.-backed 1953 overthrow of Prime Minister Mohammad Mossadegh, the Shah pursued rapid reforms through the "White Revolution," which began in 1963. The program expanded education, granted women the right to vote and introduced land redistribution.

While these measures reshaped Iranian society, they also disrupted traditional power structures. Clerics, landowners and parts of the rural population felt marginalized, and the pace of change deepened social divides rather than resolving them.

Twin Pillars and U.S. Military Buildup

Regionally, Iran's rise was closely tied to U.S. regional strategy. Starting in the late 1960s, Washington adopted the "Twin Pillars" strategy, relying on Iran and Saudi Arabia to secure the Gulf after Britain's withdrawal from the region. Iran quickly became the dominant partner, with the Shah seeking regional primacy.

Backed by soaring oil revenues, he launched a massive military expansion supported by the United States. Iran became one of the largest purchasers of American weapons, acquiring advanced aircraft and negotiating deals for sophisticated systems such as airborne warning and control platforms. According to the U.S. State Department, this relationship made Iran central to U.S. security planning in the region. At the same time, the scale of these deals sparked debate in Washington regarding oversight and the risks of transferring sensitive technology.

Relations with Israel and "Periphery Doctrine"

Alongside its alliance with Washington, Iran developed discreet but significant ties with Israel.

At the height of the Cold War, Iran's clandestine alignment with Israel was not an anomaly but part of a deliberate regional strategy. Israeli Prime Minister David Ben-Gurion advanced what became known as the "periphery doctrine" in the 1950s — a foreign policy concept aimed at breaking Israel's isolation by building alliances with non-Arab states on the edges of the Middle East. These included Iran, Turkey, and Ethiopia. The idea was simple: if Israel was surrounded by hostile Arab states, it would counterbalance them by partnering with regional powers that shared similar security concerns.

The relationship extended across energy, trade and security cooperation. Though largely hidden from public view, it reflected shared strategic concerns, particularly opposition to Arab nationalism and regional instability.

SAVAK and Repression Under the Monarchy

Internally, the Shah's rule rested not only on modernization and economic growth, but on an extensive security apparatus designed to neutralize dissent before it could become politically threatening. At the center of this system was SAVAK, created in 1957 with assistance from the CIA and Israel's Mossad. What began as an intelligence service evolved into a pervasive instrument of political control, with a mandate that stretched from counter-espionage to the monitoring of students, clerics, intellectuals and opposition groups.

The SAVAK's reach was both domestic and regional. Intelligence cooperation between Iran, Israel and Turkey formed part of a broader Cold War network aimed at tracking Soviet activity and countering Arab nationalist movements. According to intelligence histories, this collaboration included joint surveillance, interrogation of suspected Soviet agents and coordinated monitoring of neighboring states, particularly Iraq and Syria. This positioned Iran not just as a client of Western intelligence but as an active participant in regional security operations.

At home, however, the SAVAK became synonymous with repression. It maintained extensive surveillance networks and was widely feared for its ability to infiltrate opposition movements. While the Shah publicly rejected claims of systematic abuse, numerous contemporary reports and later historical accounts documented arbitrary arrests, censorship and allegations of torture. Over time, this climate of fear helped suppress open political life but also drove opposition underground, where it became more radicalized and difficult to contain.

Oil Wealth and Strategic Infrastructure

Oil was the foundation of Iran's transformation into a regional power, but it also introduced new vulnerabilities. The dramatic rise in oil prices after the 1973 crisis generated unprecedented revenues, allowing the Shah to pursue ambitious development plans, expand infrastructure and finance one of the largest militaries in the developing world. Tehran increasingly saw itself not just as a state, but as a global energy power with strategic leverage.

This economic strength translated into geopolitical influence, including in Iran's quiet but crucial relationship with Israel. Iranian oil became a lifeline for Israel, particularly at a time when Arab states imposed embargoes. A key component of this partnership was the Eilat–Ashkelon pipeline, constructed in the late 1960s to transport Iranian crude from the Red Sea to the Mediterranean, bypassing hostile routes.

Beyond oil, cooperation extended into military and technological domains. In the late 1970s, the two countries even entered joint weapons development initiatives, including the covert "Project Flower," aimed at advancing missile capabilities.

Yet this rapid accumulation of wealth also had destabilizing effects. Inflation surged, income inequality widened and development projects often outpaced the country’s administrative capacity. While the state grew richer, many Iranians felt excluded from the benefits, reinforcing perceptions that modernization was uneven and imposed from above.

Mounting Tensions

By the mid-1970s, the contradictions of the Shah's system were becoming increasingly difficult to manage. Economic expansion had created expectations that the political system could not accommodate. Inflation and rapid urbanization strained daily life, while inequality sharpened perceptions of injustice. The benefits of oil wealth were unevenly distributed, and many Iranians felt disconnected from the state's modernization project.

Political repression compounded these tensions. With opposition parties weakened or banned and dissent driven underground, grievances accumulated without institutional outlets. This created an environment in which resistance movements — whether religious, leftist or nationalist — could grow in parallel rather than being absorbed into formal politics.

At the same time, religious opposition gained momentum. A central figure was Ruhollah Khomeini, who had been exiled for criticizing the Shah but continued to mobilize support from abroad. His message resonated across social classes, uniting grievances against the monarchy.

By the late 1970s, these overlapping tensions — authoritarian rule, economic imbalance and resentment of foreign influence — created a volatile environment. What had once appeared as a stable, modernizing state began to unravel, culminating in mass protests and, ultimately, the collapse of the monarchy in 1979.

The 1979 revolution marked a dramatic turning point in Iran's history, replacing a pro-Western monarchy with a theocratic system that redefined the country's politics, society and foreign policy.

What emerged was not just a change in leadership, but a fundamental shift in how power was structured and how Iran positioned itself in the world, anchoring itself in religious authority, anti-Western rhetoric and revolutionary ideology.

From Monarchy to Theocracy

The 1979 revolution culminated in the fall of the Pahlavi monarchy and the rise of Ayatollah Ruhollah Khomeini, a cleric who had spent years in exile criticizing the Shah. When he returned to Iran in February 1979, he quickly became the revolution's central figure, shaping both its ideology and its political structure.

Khomeini introduced the concept of Velayat-e Faqih — rule by Islamic jurists — placing ultimate authority in the hands of a supreme religious leader. This marked a sharp departure from both monarchy and secular republicanism. In April 1979, Iranians voted in a national referendum to establish an Islamic Republic, and by December, a new constitution formalized clerical oversight of the state.

The new leadership moved quickly to signal a break with the old order. Iran severed ties with Israel, hosted Yasser Arafat in Tehran and handed over the former Israeli embassy to the Palestine Liberation Organization. These early decisions reflected not only ideological alignment but a broader reorientation of Iran's foreign policy away from Western alliances and toward revolutionary solidarity.

Hostage Crisis and Rupture with Washington

Tensions with the U.S. escalated rapidly. On Nov. 4, 1979, Iranian students stormed the U.S. Embassy in Tehran, taking 52 American diplomats and staff hostage. The crisis lasted 444 days and became a defining moment in contemporary U.S.-Iran relations.

U.S. President Jimmy Carter responded by freezing billions of dollars in Iranian assets and imposing sanctions. Diplomatic relations were formally severed in April 1980, a rupture that continues to shape relations decades later.

A failed U.S. rescue mission in April 1980, known as Operation Eagle Claw, further deepened tensions and embarrassed Washington. The crisis finally ended on Jan. 20, 1981, through the Algiers Accords, which secured the hostages' release in exchange for unfreezing Iranian assets and establishing a tribunal to resolve financial claims.

The embassy takeover played a decisive role inside Iran. By framing the crisis as a revolutionary struggle against American interference, hardliners marginalized more moderate factions that had favored diplomatic engagement. According to U.S. archival records, the episode strengthened Khomeini's position and helped unify competing revolutionary groups under his leadership.

Ideology

Khomeini described the U.S. as the "Great Satan," linking decades of foreign interference, including the 1953 coup, to Iran's internal repression under the Shah. This narrative became central to the Islamic Republic's legitimacy, portraying resistance to the U.S. as both a political and religious duty.

In August 1979, Khomeini established Quds Day, an annual event dedicated to expressing solidarity with Palestinians and opposition to Israel. The day is marked by state-organized rallies across Iran and in allied regions, reinforcing the government's commitment to the Palestinian cause and its broader anti-Israel stance.

These ideological pillars were embedded in Iran's constitution and early political discourse, which emphasized not only defending the revolution at home but also supporting oppressed populations abroad. This concept, often described as "exporting the revolution," signaled Iran's intention to play an active role beyond its borders.

Early Realignments and Regional Signaling

The revolution quickly reshaped Iran's regional relationships. Countries like Syria moved early to recognize and engage with the new leadership, seeing strategic opportunity in the shifting balance of power. The alignment between Tehran and Damascus would later become a cornerstone of regional politics.

Iran's early foreign policy moves like cutting ties with Israel, embracing Palestinian leadership and adopting anti-imperialist rhetoric were not merely symbolic. They marked a decisive break from the Shah's pro-Western orientation and laid the groundwork for a new geopolitical posture that combined ideology with statecraft.

At the same time, these shifts heightened tensions with neighboring states and global powers, many of whom viewed the revolution as destabilizing. Within a year, Iran would face a major external challenge as Saddam Hussein’s Iraq invaded in 1980, launching a prolonged and devastating war that would further shape the Islamic Republic's trajectory.

Revolutionary Consolidation and the Rise of Parallel Power

In the revolution's immediate aftermath, power was far from unified. Secular nationalists, leftists and Islamist factions initially competed for political power and authority, but that pluralism was short-lived. Within months, Khomeini and his allies moved to sideline rivals, using both institutional changes and revolutionary courts to consolidate control.

A key development was the creation of the Islamic Revolutionary Guard Corps (IRGC) in 1979, designed not as a traditional army but as a force loyal to the revolution itself. Over time, it evolved into one of the most powerful institutions in Iran, with influence spanning military, political and economic spheres.

At the same time, revolutionary courts carried out executions of former officials and perceived traitors, accelerating the collapse of the old order and deterring organized opposition.

On Sept. 22, 1980, Saddam Hussein's Iraq launched a full-scale invasion of Iran, igniting what would become the Iran–Iraq War (1980–1988) — the longest conventional war of the 20th century.

The conflict stemmed from territorial disputes over the Shatt al-Arab waterway, fears in Baghdad that Iran's revolutionary model might inspire Iraq's Shiite majority to revolt and broader regional rivalries. Iraq expected a quick victory, but the conflict quickly devolved into a brutal stalemate that would cost hundreds of thousands of lives on both sides.

The war devastated both populations and economies, with human losses estimated at up to a million casualties and both nations diverting disproportionate portions of their national output to the war effort. The conflict entrenched the newly established Islamic Republic in a siege mentality, reinforcing internal cohesion around wartime leadership and the revolutionary state structure.

The Tanker War

As the land war dragged on, hostilities expanded to the Persian Gulf's vital maritime routes, where both sides sought to undermine the other's economic lifelines. By 1984, the fighting had turned into what came to be known as the "Tanker War." Iran and Iraq began targeting oil tankers and commercial shipping linked to their adversary's economy. Iran attacked vessels carrying Iraqi oil or supporting Iraq, while Iraq responded with anti-ship missiles, including air-launched Exocets, against Iranian shipping and offshore facilities.

To project power and harass enemy shipping, Iran deployed a mix of Swedish-built speedboats, helicopters and small fast-attack craft, using asymmetric tactics to challenge both Iraqi and neutral shipping in the Gulf despite its limited conventional naval strength.

Between 1984 and 1988, more than 400 commercial ships were hit by missiles, mines, or attacks — dramatically disrupting oil exports from the Gulf, which was then responsible for a large share of the world's petroleum supply. The maritime war raised global energy prices, alarmed Western governments dependent on Gulf oil and turned the Gulf into a dangerous theater of naval conflict.

The attacks on commercial shipping during the Tanker War caused global oil prices to surge, raised insurance premiums for tankers operating in the Gulf and forced some shipping companies to reroute vessels around the Cape of Good Hope to avoid the Gulf.

U.S. Intervention

Though the U.S. initially proclaimed neutrality in the Iran–Iraq War, the escalating Tanker War drew it deeper into Gulf security. The U.S. had already provided clandestine support to Iraq throughout the conflict, but, in 1987, at the request of Kuwait, the U.S. launched Operation Earnest Will, under which Kuwaiti oil tankers were reflagged with the U.S. flag so they could receive American naval escorts through the Gulf.

Reflagging was intended to ensure freedom of navigation and protect oil exports from Iranian attacks without formally taking sides in the war. The operation involved warships from the U.S. Fifth Fleet escorting convoys through mined and contested waters.

Even though it was sailing under the protection of the U.S. Navy, the tanker Bridgeton, a Kuwaiti supertanker used to transport crude oil from the Gulf to international markets, struck an Iranian mine on July 24, 1987, just hours after departing Kuwait's port. The explosion tore a large hole in the ship's hull, forcing it to withdraw for repairs and underscoring that heavy warship escorts alone could not guarantee safe passage through a heavily mined Gulf.

The incident shook U.S. planners and Gulf allies because it demonstrated that Iranian mining, which was difficult to detect and clear, could threaten even well‑protected convoys. Instead of deterring Iran, the episode highlighted the vulnerability of commercial shipping in contested waters and compelled the U.S. Navy to invest more in mine‑countermeasure efforts.

Escalation

The late 1980s saw several dramatic confrontations between the U.S. and Iranian forces in the Gulf:

• In May 1987, the USS Stark was struck by two Iraqi Exocet missiles, killing 37 U.S. sailors. Although fired by Iraq, the incident highlighted the risks for U.S. forces operating amid the chaos of Gulf naval warfare.

• In April 1988, the USS Samuel B. Roberts hit an Iranian mine, prompting the U.S. to launch Operation Praying Mantis, the largest surface naval engagement for the U.S. since World War II. U.S. forces struck Iranian oil platforms and naval units, significantly damaging Iran's naval capability.

• In July 1988, the U.S. cruiser USS Vincennes shot down Iran Air Flight 655, killing 290 civilians. The U.S. government later described the incident as a tragic error in a high‑tension environment, while Iran condemned it as a deliberate act. The episode led to legal claims and eventual compensation under international procedures.

These confrontations pushed the U.S. beyond convoy protection into direct armed clashes with Iranian forces, reshaping naval dynamics in the Gulf.

Legal Fallout

The intense maritime operations culminated in legal disputes. After the war, Iran brought a case against the United States before the International Court of Justice (ICJ) under the 1955 Treaty of Amity, asserting that U.S. attacks on oil platforms and other actions violated treaty protections. In the Oil Platforms case, the ICJ ultimately ruled on jurisdiction and weighed competing claims about military necessity versus treaty obligations, illustrating how the conflict's legal and diplomatic legacies extended far beyond the battlefield.

Lasting U.S. Security Role

The Iran–Iraq War formally ended with a ceasefire in August 1988, but the U.S. naval presence and security role in the Gulf persisted. Operation Earnest Will evolved into sustained patrols, mine‑countermeasure missions and a permanent forward presence designed to deter aggression against commercial shipping and reassure Gulf allies.

Analysts at the time offered conflicting views. Some argued that the reflagging and naval deployments were necessary to prevent escalation and maintain U.S. credibility in Gulf security commitments. Others warned that expanding U.S. military involvement risked entangling Washington in conflicts not of its own making — foreshadowing debates that would continue into the 21st century.

The legacy of the 1980s shaped later U.S.–Iranian maritime tensions, informed naval doctrines for freedom of navigation operations, and contributed to the pattern of U.S. military engagement in the Gulf that persists to the present day.

Iran's regional strategy is rooted in the Iranian Revolution, which transformed the country from a U.S.-aligned monarchy into an Islamic republic led by Ruhollah Khomeini.

The new leadership redefined Iran's foreign policy around opposition to Western influence and hostility toward Israel, while promoting itself as a defender of oppressed Muslim populations, particularly the Palestinians. This ideological shift was paired with a pragmatic security calculation: Iran, relatively weaker in conventional military terms, would rely on asymmetric methods to deter more powerful adversaries, especially the U.S. and Israel.

To implement this approach, Tehran relied heavily on the IRGC and, in particular, its external operations arm, the Quds Force. Rather than projecting power through traditional interstate warfare, Iran began cultivating networks of allied armed groups and political movements across the region. Over time, this model would evolve into what analysts now refer to as the "Axis of Resistance," a loose network of state and non-state actors aligned with Iran's regional objectives.

Coordinated to varying degrees by the Quds Force, this network has allowed Tehran to project power through partners embedded in local political and social systems. Rather than relying on direct confrontation, Iran's strategy emphasizes deterrence through dispersion, enabling it to threaten adversaries from multiple directions while limiting its own exposure.

Lebanon and Hezbollah's Rise

Iran's first and most consequential success in building its network of allied non-state actors came in Lebanon in the early 1980s, in the context of both the Iranian Revolution and the 1982 Israeli Invasion. After Israel's invasion and occupation of large parts of southern Lebanon, the IRGC deployed several hundred advisers to Lebanon's Bekaa Valley, then under Syrian control. There, working with local clerics and militants, Iran helped consolidate disparate Shiite factions — many of which had broken away from the more secular Amal Movement — into what would become Hezbollah.

Hezbollah formally announced its existence in 1985 through an "Open Letter" that explicitly aligned the group ideologically with Iran's revolutionary doctrine of Wilayat al-Faqih, pledging allegiance to Khomeini. From the outset, Iran provided extensive support including financial aid, military training, weapons transfers and religious-ideological guidance, which allowed Hezbollah to evolve far beyond a typical militia. Throughout the 1980s and 1990s, the group carried out guerrilla operations against Israeli forces and their allies in southern Lebanon, gradually positioning itself as the leading force of "resistance" in the country.

Israel's withdrawal from southern Lebanon in 2000 marked a turning point, widely framed by Hezbollah as a victory that boosted its domestic legitimacy. Over time, the group expanded into a hybrid actor, combining a sophisticated military apparatus with deep political and social roots. It established a vast welfare network including schools, clinics and reconstruction programs, particularly in marginalized Shiite communities, embedding itself firmly within Lebanon's social fabric while also entering formal politics, winning seats in parliament and cabinet positions.

This dual structure proved especially consequential during the 2006 war with Israel, when Hezbollah demonstrated an unexpected level of military capability, including disciplined command structures, advanced rocket systems and defensive tactics that challenged the Israeli military. Although Lebanon suffered heavy destruction, Hezbollah's ability to withstand the assault reinforced its image as a formidable non-state actor and significantly elevated its strategic value to Tehran.

For Iran, Hezbollah became the cornerstone of what would later be described as the Axis of Resistance: a forward-operating partner capable of deterring Israel, projecting Iranian influence into the Levant and serving as a model for other aligned groups. The organization's blend of insurgency, political participation and social service provision illustrated a replicable strategy, one that Iran would later adapt, with variations, in Iraq, Syria and beyond.

Iraq

The 2003 Iraq War created a major opening for Iran to expand its influence westward. The fall of Saddam Hussein removed a key regional rival and allowed Tehran to cultivate ties with Shiite political parties and armed groups. Over time, Iran supported the growth of several militias, including Kataib Hezbollah, Asaib Ahl al-Haq and the Badr Organization, many of which later became part of the Popular Mobilization Forces (PMF).

Iran's influence in Iraq was not limited to military support. It extended into politics, economics and religious networks, allowing Tehran to shape decision-making in Baghdad while maintaining plausible deniability through its partners. Iraq also became strategically vital as a geographic bridge, linking Iran to Syria and Lebanon and enabling the movement of personnel and weapons across the region. This combination of territorial access and local alliances made Iraq a central pillar of Iran's emerging regional architecture.

Syria

The outbreak of the Syrian Revolution and Civil War in 2011 marked a decisive phase in the evolution of Iran's strategy. As the government of Bashar al-Assad came under threat, Iran intervened to prevent the collapse of a key ally. It deployed military advisers from the IRGC, mobilized Hezbollah fighters and recruited additional Shiite militias from across the region.

This intervention had long-term strategic consequences. By helping sustain the Syrian government, Iran secured a continuous land corridor stretching from its own territory through Iraq and Syria to Lebanon. Analysts widely view this corridor as a crucial element of Iran's deterrence strategy, allowing it to maintain supply lines to Hezbollah and project influence toward Israel's borders. The Syrian war thus transformed Iran's network from a set of discrete relationships into a more integrated and geographically connected system.

Gaza and Yemen

Beyond Lebanon, Iraq and Syria, Iran extended its support to armed groups operating in other arenas, particularly in Gaza and Yemen. Tehran has long backed Palestinian Islamic Jihad and has also provided varying levels of support to Hamas, including funding, weapons and technical expertise. Although relations with Hamas were strained during the Syrian war, they later improved.

In Yemen, Iran is allied to Ansar Allah, which is often referred to as the Houthis. Iran provided support for the Houthis' missile and drone programs, expanding the geographic reach of Iran's influence. Iranian assistance has contributed to the Houthis' ability to strike regional targets and disrupt maritime traffic in the Red Sea.

Iran's nuclear program, which began not as a clandestine effort but as a Western-supported project, has been a central point of contention in the lead-up to the current conflict.

Under the Shah, Iran was a close U.S. ally and a participant in Washington's "Atoms for Peace" initiative. In the 1960s and 1970s, the country invested in civilian nuclear energy with Western assistance, including plans for multiple reactors and fuel-cycle capabilities. At the time, the program was framed as part of Iran's modernization and energy diversification strategy.

This trajectory changed dramatically after the Iranian Revolution. The new leadership under Ayatollah Khomeini initially froze or slowed nuclear activities, viewing them as tied to the previous government. However, the Iran–Iraq War, particularly Iraq's use of chemical weapons, reshaped Iran's security doctrine. Iranian leaders increasingly saw strategic technologies, including nuclear capabilities, as a form of deterrence in a hostile regional environment.

By the late 1980s and 1990s, Iran quietly revived its nuclear efforts, developing infrastructure that could support both civilian energy production and, potentially, more sensitive capabilities.

Natanz, Arak and International Scrutiny

The modern crisis over Iran's nuclear program began in 2002, when previously undisclosed facilities at Natanz and Arak were revealed. Natanz became the center of uranium enrichment, where uranium is processed into fuel that can power reactors but can also, at higher levels, be used in nuclear weapons. Arak, a heavy-water reactor, raised concerns because it could produce plutonium, another pathway to a bomb.

These revelations triggered inspections by the International Atomic Energy Agency and a prolonged confrontation between Iran and the international community. The IAEA reported gaps in Iran’s disclosures and pressed for greater transparency, while Western governments accused Tehran of pursuing capabilities that could lead to nuclear weapons. Iran, for its part, insisted its program was peaceful and within its rights under the Nuclear Non-Proliferation Treaty.

The result was a cycle of negotiations and sanctions. The United Nations imposed multiple rounds of sanctions targeting Iran's banking, oil and technology sectors, aiming to pressure Tehran into limiting its program.

Covert Operations

As diplomatic pressure intensified, the nuclear issue moved into a covert phase. One of the most consequential operations was the Stuxnet cyberattack, widely attributed to the U.S. and Israel. The malware infiltrated Iran's Natanz facility and caused centrifuges, which are machines used to enrich uranium, to malfunction and destroy themselves, setting back parts of the program without a conventional military strike.

This marked a turning point in modern conflict, demonstrating that cyber tools could physically damage critical infrastructure. Alongside cyber operations, a series of assassinations targeted Iranian nuclear scientists in the early 2010s. These killings, widely attributed in international reporting to Israeli intelligence, were intended to disrupt technical progress and create uncertainty within Iran's scientific community.

Together, these efforts formed a shadow war aimed at slowing Iran's nuclear advances while avoiding open conflict.

Nuclear Deal

After years of escalating tensions, Iran and world powers reached the Joint Comprehensive Plan of Action (JCPOA) in 2015. The agreement imposed strict limits on Iran's nuclear program in exchange for sanctions relief.

Under the deal, Iran reduced its enriched uranium stockpile, capped enrichment levels at 3.67%, and limited the number and type of centrifuges it could operate. The Arak reactor was redesigned to prevent plutonium production, and Iran accepted an unprecedented level of monitoring by the IAEA, including inspections and surveillance mechanisms.

A key concept in the agreement was "breakout time" — the time it would take Iran to produce enough fissile material for a nuclear weapon. The JCPOA extended this timeline to roughly one year, providing what negotiators saw as a buffer for detection and response.

U.S. Withdrawal From the JCPOA

In 2018, the United States under Donald Trump withdrew from the agreement and reimposed sanctions as part of a "maximum pressure" campaign. The move aimed to force Iran into accepting broader restrictions, including on its missile program and regional activities.

Iran initially remained within the deal's limits but gradually began scaling back its commitments. It increased enrichment levels far beyond the JCPOA cap, reaching up to 60%, and installed more advanced centrifuges capable of producing enriched uranium more quickly. It also reduced cooperation with IAEA monitoring, including disconnecting cameras and limiting inspections.

These steps significantly shortened Iran's breakout time. According to expert assessments, Iran's timeline to produce enough fissile material for a nuclear weapon has dropped from about one year under the deal to potentially weeks or months.

Monitoring Disputes and Reduced Transparency

In recent years, tensions between Iran and the IAEA have increasingly centered on access and transparency. Inspectors have reportedly detected uranium particles enriched to levels close to weapons-grade at certain sites, raising concerns about undeclared activities. At the same time, Iran has restricted monitoring measures, including removing surveillance equipment and limiting inspector access.

The IAEA has warned that these steps complicate its ability to verify that Iran's program remains peaceful. Without consistent monitoring, even civilian nuclear activities can become difficult to assess, increasing uncertainty and mistrust between Iran and the international community.

On Oct. 7, 2023, Hamas launched a major assault on Israel from Gaza, leading to multiple wars across the region between the U.S., Israel, Iran and their respective allies.

Many analysts and open sources report that the IRGC, namely the Quds Force, had longstanding ties to Hamas and Palestinian Islamic Jihad, including training, logistical support and planning assistance in the months before the attack. Some reporting suggests IRGC commanders in Beirut helped oversee planning, though Tehran denied direct operational control or influence.

The attack killed around 1,200 people in Israel, mostly civilians, and triggered one of the largest military confrontations in the region in decades, extending far beyond Gaza. This became the spark that ignited a wider conflict involving proxies and state actors aligned with Iran across multiple theaters.

Hezbollah Opens a Northern Front

Almost immediately after Oct. 7, Hezbollah opened fire on Israeli positions across the northern border from Lebanon, stating that it was acting in solidarity with Hamas' attack and to pressure Israel to fight on two fronts, a step that quickly escalated into daily exchanges of fire across the Israel–Lebanon frontier.

These clashes forced tens of thousands of northern Israeli residents to evacuate and displaced large numbers of civilians in southern Lebanon, as both sides traded rockets, artillery, airstrikes and drone strikes through 2023 and 2024, in the most sustained conflict between Hezbollah and Israel since the 2006 war. 

In late November 2024, after Israel killed Hezbollah's long-time leader Hassan Nasrallah, Lebanon and Israel signed a U.S. and French‑brokered ceasefire requiring Hezbollah to withdraw fighters north of the Litani River and the Lebanese Army to deploy to the south, with a multinational panel led by the U.S monitoring implementation, though violations and tensions continued even after the agreement. 

Despite the ceasefire in late 2024, the underlying tensions and near-daily Israeli strikes on southern Lebanon persisted. Israel argued that Hezbollah was using the ceasefire to rearm and reconstitute its forces.

Houthi Escalation

Outside the Levant, Iran's influence also appeared in Yemen's Red Sea conflict, where the Iran‑aligned Houthi movement dramatically expanded attacks on commercial and military shipping after late 2023.

Beginning in November 2023, the Houthis launched missiles, drones and explosive boats against vessels transiting the southern Red Sea, Bab al‑Mandeb Strait and Gulf of Aden, targeting both merchant ships and military vessels as part of their campaign tied to the broader Middle East conflict. U.S. and allied officials have recorded dozens of attacks, with some independent analysts estimating more than 100 strikes on shipping since late 2023 that significantly disrupted global trade, pushed many companies to reroute traffic around Africa's Cape of Good Hope and led to sharp increases in freight costs and insurance premiums.

In response, the United States established a multinational maritime security coalition, including operations such as Operation Prosperity Guardian, to patrol and help protect merchant traffic through the critical Red Sea corridor. Reuters and U.S. defense reporting also cited Iranian support for the Houthis, noting that Tehran has provided weapons, targeting assistance and military advice that enhanced the group's ability to project force into international waters.

IRGC and Hezbollah commanders were also reported to have been present in Yemen, helping coordinate some of the targeting and operations. While Saudi territory was largely spared direct Houthi attacks, the expansion of Houthi strikes against international shipping turned the conflict into a regional economic and security crisis affecting global maritime commerce.

Direct Escalations

Between 2023 and 2025, Iran's strategy blended indirect attacks with occasional direct confrontations. Iran's first-ever direct attack on Israel occurred in April 2024, after an Israeli strike on an Iranian consular compound in Damascus killed IRGC commanders. Iran launched missile and drone attacks on Israeli territory, though the situation did not immediately escalate.

Iran launched its second direct attack on Israel in October 2024, firing approximately 180–200 ballistic missiles in at least two waves, primarily targeting military sites such as airbases and intelligence facilities. This assault came in retaliation for Israeli actions, including the killings of senior figures like Hamas leader Ismail Haniyeh, Hezbollah leader Hassan Nasrallah and an IRGC commander. Most of the missiles were intercepted by Israeli air defenses, with assistance from the U.S. and Jordan, resulting in limited damage.

These rounds of tit‑for‑tat operations underscored how the conflict had evolved from a Gaza‑centered war into a wide‑ranging Iran–Israel confrontation, involving cross‑border attacks, airstrikes, maritime disruptions, and proxy engagements across Lebanon, Iraq, Syria and Yemen.

The 12‑Day War

The most intense phase of direct confrontation between Israel and Iran occurred in mid‑June  2025, when long‑standing regional tensions erupted into the first full‑scale clash between the two states since the wider Middle Eastern crisis began. On June 13, 2025, Israel launched a surprise aerial campaign striking Iran's nuclear, military and missile infrastructure, including facilities at Natanz, Isfahan and other sites, with waves of fighter jets hitting over 100 targets across multiple provinces.

Israeli officials said strikes killed a large number of senior Iranian military commanders and nuclear scientists, severely degrading air defenses and missile production capabilities. Iran immediately retaliated with hundreds of ballistic missiles and a large number of drones aimed at major Israeli population centers, military sites and strategic infrastructure. Though many were intercepted by Israeli defenses, others caused damage and casualties in central and northern cities, including Tel Aviv, Rishon LeZion and Haifa. 

Israel also reported that Iran's barrages included direct hits on Israeli military sites. During the war's second week, the U.S. directly intervened in the conflict, conducting airstrikes on three key Iranian nuclear facilities, Natanz, Fordow and Isfahan, using heavy‑bomber and cruise missile strikes in a coordinated offensive intended to set back Tehran's nuclear program. 

The fighting inflicted deaths and injuries on both sides, damaged civilian and energy infrastructure, forced evacuations, and raised global fears of broader escalation. Estimates indicate that Iran's losses, including military personnel, scientists, and support staff, far exceeded Israeli casualties. By June 24, 2025, a U.S.‑brokered ceasefire was announced, bringing the roughly twelve days of intense combat to a pause, though tensions persisted and larger political disputes over nuclear issues remained unresolved.

The conflict marked a significant escalation, involving unprecedented direct Iranian missile strikes on Israel and coordinated U.S.‑Israeli bombardment of Iranian strategic sites.

Ceasefire and Regional Aftershocks

After nearly two weeks of intense exchanges, a ceasefire was reached in late June 2025. Though formal hostilities paused, the effects persisted. Missile salvos, air defenses and strategic artillery had inflicted civilian and military casualties on both sides, and the conflict drew global attention for its potential to escalate further.

Regional dynamics shifted as well. The Red Sea disruption pressured global shipping routes, prompting multinational naval efforts to protect commerce, while analysts warned that multiple fronts remained active, from Lebanon to Yemen, even after peace agreements.

The ceasefire that ended the 12-Day War halted the most intense direct confrontation between Iran and Israel until that point but left both sides in a state of high alert.

Israel had struck Iranian military and nuclear-linked infrastructure, while Iran had demonstrated its ability to retaliate directly with long-range missiles, marking a departure from its traditional reliance on non-state allies.

In the immediate aftermath, Iran entered a phase of damage assessment and reconstruction. Analysts noted that Tehran prioritized restoring elements of its missile program and reinforcing air defenses, while avoiding immediate escalation that could invite another round of direct strikes. At the same time, Israel maintained a posture of preemptive containment, continuing strikes against Iranian-linked targets in Syria and along logistical corridors used to supply allied groups.

This period was characterized by what security analysts describe as "deterrence without resolution"—a temporary pause in large-scale conflict but no political settlement.

Diplomacy Resumes

At the start of 2026, diplomatic efforts re-emerged, with indirect talks between Iran and the U.S. taking place in Geneva. These discussions focused on Iran's advancing nuclear program, which had accelerated after the collapse of the 2015 nuclear deal and the disruptions of the 2025 war.

However, the talks were overshadowed by protests in Iran and deep mistrust between Tehran and Washington. Western governments raised concerns about Iran's higher uranium enrichment levels and reduced cooperation with inspectors from the IAEA, while Tehran insisted on sanctions relief and guarantees against future U.S. withdrawal from agreements.

Collapse of Talks and Coordinated U.S.–Israel Strikes

On Feb. 28, 2026, the U.S. and Israel launched coordinated strikes on Iranian territory, which has since expanded into a multi-front regional war involving missile exchanges, naval threats and economic disruption. Washington framed the operation as a preemptive response to imminent Iranian threats, while Israel described it as part of its broader campaign to degrade Iran's nuclear and missile capabilities.

The strikes targeted missile systems, air defenses and facilities linked to Iran's nuclear infrastructure, marking a return to direct confrontation. The strikes on Iran since late February have killed a significant portion of the country's top political and military leadership, including Supreme Leader Ayatollah Ali Khamenei, alongside senior figures such as national security chief Ali Shamkhani, IRGC commander Mohammad Pakpour, Armed Forces Chief of Staff Abdolrahim Mousavi, and Defense Minister Aziz Nasirzadeh.

The campaign has also targeted Iran's broader command structure, with Israel saying dozens of senior officials were killed in the opening strikes alone and subsequent attacks eliminating intelligence chiefs, IRGC aerospace leadership, Basij commanders and senior security council officials. Overall, Israeli and U.S. officials claim the strikes decapitated Iran's leadership, with roughly 40 top figures killed in the initial wave and dozens more since, while wider estimates suggest over 1,000 Iranian security personnel have died and more than 1,500 total fatalities have been reported nationwide, including civilians.

Iran responded almost immediately with ballistic missiles and drone attacks targeting Israeli cities and U.S. military bases across the region, including those in the Persian Gulf. Within days, the conflict escalated into a broader war involving multiple countries and theaters, transforming what had long been an indirect rivalry into open hostilities.

The war has been fought across multiple domains at once. U.S. and Israeli forces have conducted sustained airstrikes inside Iran, hitting military installations, infrastructure, and urban areas, including parts of Tehran. At the same time, Iran has launched repeated waves of missile and drone attacks against Israeli territory, with some strikes reaching deep into southern Israel and causing civilian casualties.

The battlefield is not confined to Iran and Israel. Attacks and military operations have spread across the Middle East, including Iraq, Lebanon, and the Gulf countries, where U.S. bases and allied infrastructure have been targeted. This has turned the conflict into a regional war zone, with overlapping fronts and constant risk of further escalation.

Minab School Strike

The Minab school strike occurred on the morning of Feb. 28, 2026, making it one of the war's opening moments. A series of precision-guided missiles, identified as U.S. Tomahawk cruise missiles, struck the Shajareh Tayyebeh girls' elementary school in the Shahrak-e Al-Mahdi neighborhood of Minab, Hormozgan Province, southern Iran, around 10:23–10:45 a.m. local time.

The school, which housed roughly 170–264 students (mostly girls aged 7–12) along with teachers and parents at the time, was located directly adjacent to an Islamic Revolutionary Guard Corps (IRGC) naval missile brigade compound. Iranian authorities and independent monitors reported 156–175 deaths (commonly cited as 168, including over 100–110 children) and dozens more injured, making it one of the deadliest single civilian incidents of the conflict. Video footage, eyewitness accounts, and satellite imagery showed extensive destruction to the school buildings, with parents later describing scenes of children trapped in rubble.

Initial media narratives diverged sharply along geopolitical lines. Iranian state media and officials immediately framed the strike as a deliberate U.S.-Israeli war crime and act of barbarism targeting civilians and children, emphasizing it occurred amid indirect U.S.-Iran negotiations and portraying it as proof of unprovoked aggression rather than strategy.

In contrast, early U.S. statements and some Western reporting were cautious. President Trump initially blamed Iran or expressed uncertainty, while the Pentagon acknowledged awareness of civilian harm reports but launched an internal investigation without confirming responsibility. Some outlets highlighted the school's proximity to the IRGC base as context for a possible targeting mix-up.

Independent early evidence, such as verified videos, social media posts from the scene, and preliminary satellite imagery, began emerging within days, showing damage consistent with a precision strike during the opening U.S. air campaign, but competing claims persisted in the fog of the first days and weeks.

Within weeks, a broad consensus emerged across independent investigations, journalists, and even preliminary U.S. military findings that the strike was carried out by U.S. forces due to a targeting error based on outdated intelligence. The Defense Intelligence Agency had retained old data labeling the site as part of the adjacent IRGC naval base from before the school was physically separated, fenced, and repurposed as a civilian facility between 2013 and 2016.

Analyses by The New York Times (visual investigations using satellite imagery and missile fragment evidence), Amnesty International (video, imagery, and on-site interviews), Reuters (sourcing U.S. military insiders), CNN, and others confirmed U.S. Tomahawk involvement. A U.S. internal probe reached the same conclusion, though the full investigation remains ongoing as of April 2026. The U.N. Human Rights Council and human rights groups have called for full accountability.

Iran's Response

In the wake of Supreme Leader Ayatollah Ali Khamenei's killing, his son Mojtaba was elected as the new supreme leader. His health and status are unclear, and the supreme leader has only addressed the world via written letters.

Iran's response has focused on asymmetric warfare and regional escalation. Rather than relying solely on conventional military engagement, Iran has used missiles, drones and regional pressure points to expand the conflict and impose costs on its adversaries. These strikes have targeted Israeli cities, U.S. bases and infrastructure across multiple countries.

In the UAE, Iranian missiles have hit Al Dhafra Air Base (a key U.S. facility), Abu Dhabi residential areas near Zayed International Airport, the Jebel Ali port in Dubai and the Al Hosn Gas Field, with debris from interceptions causing fires and injuries in the Khalifa Economic Zone. As of early April, the UAE reported over 400 missiles and 2,000 drones launched at its territory.

Saudi Arabia faced attacks on its Ras Tanura oil refinery and Aramco facilities in the Eastern Province, the U.S. Embassy in Riyadh, Riyadh International Airport and petrochemical sites like the Samref Refinery and Jubail Complex. Qatar saw missiles hit the Ras Laffan Industrial City (damaging LNG terminals and QatarEnergy operations) and Al Udeid Air Base. Kuwait was struck at Kuwait International Airport (fuel tanks and radar) and Ali Al-Salem and Arifjan U.S. bases. Bahrain endured drone strikes on Salman Port (U.S. Fifth Fleet headquarters) and hotels in Manama. Oman reported damage at Salalah Port from drones.

Beyond the Gulf, Iran has launched missile and drone barrages at other parts of the Middle East, focusing on Israeli targets and U.S.-linked sites in Iraq and Jordan. Against Israel, the IRGC has launched dozens of waves under Operation True Promise 4, striking military and strategic locations in Tel Aviv, Haifa, Kiryat Shmona, Dimona, and northern areas, including command centers and infrastructure tied to defense firms like Elbit Systems.

In Iraq, strikes hit Erbil International Airport, the U.S. Consulate in Erbil, Harir Airbase, a hotel in Sulaymaniyah (Titanic Hotel), and nearby U.N. facilities, alongside attacks on Kurdish positions. Jordan's Muwaffaq al Salti Air Base (hosting U.S. forces) was also targeted with ballistic missiles. While most projectiles have been intercepted by regional defenses, confirmed hits have caused limited structural damage, civilian casualties, and disruptions to airports, energy sites, and diplomatic facilities.

The Strait of Hormuz

One of the most consequential dimensions of the war is its impact on the Strait of Hormuz, a narrow waterway through which roughly a fifth of the world's petroleum liquids consumption transits each day, according to the U.S. Energy Information Administration. The strait is the primary export route for Gulf producers, including Saudi Arabia, Iraq, Kuwait and the UAE, making it one of the most critical arteries in the global energy system. Iranian officials have repeatedly threatened to restrict traffic through the passage, while naval incidents, including seizures and harassment of commercial tankers, have already disrupted shipping patterns and increased transit risks.

The impact has been immediate in global markets. Oil prices have shown sharp volatility following each escalation, with benchmark crude rising on fears of supply disruption before retreating as markets reassess the likelihood of sustained closures, according to Bloomberg and the International Energy Agency. Shipping costs have also surged, as insurers raised war risk premiums for vessels transiting the Gulf, a dynamic that echoes the "Tanker War" phase of the Iran–Iraq War. Analysts warn that even limited disruptions can ripple across supply chains, increasing fuel prices, transportation costs, and ultimately consumer inflation worldwide.

Energy economists caution that a prolonged or intensified disruption in the strait could trigger a shock comparable to past crises, such as the 1973 oil crisis, when supply constraints drove a global economic downturn. While alternative routes and strategic reserves provide some buffer, they are insufficient to fully offset a sustained blockage of Hormuz flows, experts at the International Monetary Fund and major financial institutions warn. As a result, the conflict's trajectory in the Gulf is being closely watched not only as a regional security issue but as a potential trigger for a broader global economic shock.

U.S. Role and Military Buildup

The Pentagon has ordered thousands of additional U.S. troops to the Middle East, primarily to support operations related to the war and to provide strategic options for further escalation. Plans include deploying around 3,000–4,000 soldiers from the Army's 82nd Airborne Division as a rapid-response force.

Earlier reinforcements included about 2,500 Marines and accompanying naval assets aboard amphibious assault ships such as the USS Boxer, enhancing both force posture and deterrence capabilities.

Some reports suggest the total U.S. military footprint in the region — including pre‑existing bases and new deployments — now exceeds 50,000 troops, with rotating Marine Expeditionary Units and airborne forces supplementing the force. These troops were positioned across multiple countries and facilities in the Gulf, with priorities including protecting U.S. personnel and assets, supporting allied air operations, and securing key areas such as the Strait of Hormuz.

U.S. Casualties

As of March 25, 14 American service members have been killed in the war with Iran. These include fatalities in multiple incidents such as Iranian strikes and a military aircraft crash supporting operations. The list includes logistics soldiers killed in a drone strike on their command center in Kuwait, troops who succumbed to wounds sustained in Saudi Arabia and aircrew members who died when a U.S. refueling aircraft crashed in western Iraq while operating in the theater.

Lebanese Front

The conflict expanded to Lebanon in early March after Hezbollah fired rockets into Israel as part of the broader Iran war. Hezbollah resumed large‑scale rocket and drone barrages into northern Israel shortly after the U.S.–Israel strikes on Iran, marking one of the most serious escalations on that front. Israel has responded with intense air and artillery strikes throughout southern Lebanon and parts of Beirut, resulting in more than 2,000 deaths and massive displacement of civilians.

The Lebanese government has publicly condemned Hezbollah's actions, labeled the group's military operations unauthorized and moved to ban its armed activities, illustrating internal political divisions over the conflict. Lebanon also expelled Iran's ambassador amid fears that Tehran's influence is pulling the country into a wider war. This escalation has triggered fears of a sustained two‑front confrontation for Israel and deepened the humanitarian crisis in Lebanon.

Iraqi Front

The war has also spilled into Iraq, where Iran‑backed militias and elements connected to Tehran have broadened their engagement. Iraqi territory has seen drone and missile strikes against foreign bases and coalition forces, including attacks on the Baghdad Airport, where U.S. troops are stationed.

These militias, often embedded within Iraq's complex security landscape, have used Iraqi soil to launch attacks on U.S. and allied positions, triggering defensive responses and raising tensions with Baghdad. While the Iraqi government's official involvement remains limited, the presence and activity of these groups have made Iraq another active front in the regional conflict, heightening risks for both local stability and foreign troops stationed there.

Ceasefire

On April 7, 2026, Pakistan, which has acted as a mediator between the U.S. and Iran, announced a ceasefire, only hours before Trump's deadline. Earlier in the day, Trump had threatened that "A whole civilization will die tonight" if a deal wasn't struck, vowing to bomb Iran's power plants and bridges.

The ceasefire ended U.S. and Israeli strikes on Iran in exchange for the opening of the Strait of Hormuz, a pause in missile and drone fire, and negotiations to end the war. Pakistani Prime Minister Shehbaz Sharif stated when he announced the ceasefire that Lebanon would also be included in the agreement. However, hours after the announcement, Israel launched a massive wave of strikes across Lebanon that killed at least 357 people and injured over 1,200. In Beirut, the strikes hit dense residential neighborhoods, with whole buildings collapsing without warning.

Israel, which claimed that Lebanon wasn't included in the ceasefire, said that it targeted Hezbollah members, such as the secretary of Hezbollah leader Naim Qassem, that had left Shiite-majority neighborhoods of the city and were hiding elsewhere. The U.S. supported Israel's description of the ceasefire, with Iran responding by continuing its closure of the Strait of Hormuz.

A direct round of talks began in Pakistan on April 11, 2026, with tensions soon escalating. Trump dispatched Vice President JD Vance, U.S. Middle East envoy Steve Witkoff and Jared Kushner, the president's son-in-law. The Iranian team has been headed by Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi accompanied by around 70 advisors.

Negotiations concluded a day later without a peace deal after approximately 21 hours of marathon talks. The U.S. delegation presented what it called its "final and best offer," centered on Iran forgoing nuclear weapons capabilities, verifiable limits on its program, sanctions relief and regional de-escalation. Iran's team, headed by Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, rejected key demands as excessive and unreasonable, insisting on issues like war reparations, full sanctions lifting and no restrictions on its nuclear program. Both sides blamed the other for the impasse, with Vance stating Iran refused to accept U.S. terms and Iranian officials claiming the U.S. failed to build trust.

Trump announced via Truth Social that the U.S. will immediately begin a naval blockade of the Strait of Hormuz in response to Iran's continued control over the waterway. He stated that the U.S. Navy would block any and all ships trying to enter or leave the strait, interdict vessels that paid illegal tolls to Iran, and destroy Iranian-laid mines, warning that any Iranian attacks on U.S. or peaceful vessels would be met with overwhelming force. Trump framed the move as ending Iran's "illegal act of extortion" and noted that other countries would participate, aiming to restore free passage for global shipping amid ongoing high energy prices. The announcement escalated tensions just days into a fragile two-week ceasefire.

A critical arena of the conflict has been fought in the media, where competing claims regarding the war's efficacy and Iran's performance have often been intense.

Several topics have proven particularly controversial, namely Israel's role in launching the war, the extent of damage caused by Iranian attacks and the use of a large number of missile interceptors. These concerns have been dominant in discussions on social media and traditional media.

Israel's Role and Epstein Files

Likely the most divisive discussion regarding the Iran War has been the role of Israeli Prime Minister Benjamin Netanyahu and other pro-Israel figures in influencing Trump's decision to go to war.

Multiple accounts describe a pivotal Feb. 11, 2026, White House Situation Room meeting where Netanyahu (joined remotely by Mossad chief David Barnea) presented intelligence and assurances that a joint U.S.-Israeli campaign could rapidly destroy Iran's missile program, keep the Strait of Hormuz open and even trigger regime change within weeks, promises that reportedly swayed Trump despite internal U.S. warnings of chaos and high costs.

Commentators have also pointed to the release of the Epstein Files as a reason that drove Trump's decision to go to war. Due to Jeffrey Epstein's alleged ties to Israeli intelligence, some have posited that Trump is either trying to distract from the scandal or is being blackmailed.

Iranian Attacks

Iran's retaliatory strikes under Operation True Promise 4 have repeatedly targeted critical power infrastructure and desalination plants across the Gulf, incidents that some analysts argue receive less sustained attention in Western coverage focused on high interception rates and the degradation of Iranian capabilities.

In Kuwait, Iranian drones and missiles struck power and water desalination facilities on multiple occasions in late March and early April 2026, causing outages to electricity-generating units, fires at oil sites and at least one confirmed worker death with injuries to others. Kuwaiti officials described "serious material damage" to plants vital for both power and potable water.

Bahrain reported an Iranian drone hit on a desalination plant in early March that affected water supplies to dozens of villages, while the UAE and Saudi Arabia saw strikes on related energy complexes (including gas fields and refineries) that disrupted operations even when partially intercepted. These facilities supply drinking water to tens of millions in the water-scarce region and are often co-located with power generation, meaning damage cascades into blackouts and humanitarian strain.

Similar patterns appear in strikes on Israeli infrastructure, where Iranian barrages have hit energy nodes linked to power grids and refineries, producing localized blackouts and industrial disruptions that are sometimes framed as minor or quickly contained. Reports detail impacts on facilities near Haifa and other sites, with shrapnel and secondary effects knocking out portions of the electricity grid in connected areas. While Israeli defenses claim most projectiles are downed, the cumulative effect of repeated waves — including those using decoys and maneuverable warheads — has forced temporary shutdowns and raised concerns about longer-term grid stability, yet these details often appear as brief asides in coverage emphasizing overall interception success.

Many commentators suggest that Western media downplays these hits because they complicate narratives of decisive U.S.-Israeli dominance, instead highlighting Iranian "declining fire rate" while giving less airtime to the rising precision and economic/human costs of the lower-volume salvos. Desalination plants, which provide 70–100% of drinking water in several Gulf states, represent a particularly sensitive target whose damage risks civilian hardship, potential evacuations, and ripple effects on hospitals, agriculture, and industry — outcomes that could erode public support for the campaign if emphasized.

U.S. Casualties

Iran has claimed that its forces killed or wounded around 650 U.S. troops in the first two days of major retaliatory strikes under Operation True Promise 4.

Specific breakdowns in Iranian announcements include claims of around 160 killed or wounded in a single strike on a U.S. facility in Bahrain and additional heavy casualties from hits on bases in the UAE, Kuwait, Saudi Arabia and elsewhere. Later statements have referenced cumulative figures in the hundreds, often framing them as part of ongoing barrages against U.S. bases across the Gulf and broader region. Iranian officials, including IRGC spokespeople like Ali Mohammad Naini, have accused the U.S. of concealing the true toll and misrepresenting some captured personnel as combat deaths.

In addition to those killed, the U.S. has said around 346 soldiers have been injured in the conflict. Allegations have circulated widely, particularly from Iranian officials and state-linked media, that the U.S. military relocated thousands of troops from damaged bases in the Gulf to civilian hotels and office buildings to shield them from Iranian missile and drone strikes.

Iran's Foreign Minister Abbas Araghchi and armed forces spokesman Abolfazl Shekarchi accused the U.S. of "fleeing" military installations and using hotels in densely populated urban areas as cover, effectively turning civilian sites into legitimate military targets. Iranian spokespeople warned that any hotel housing U.S. personnel would be considered an "American" facility and subject to attack, urging regional hotels to refuse bookings for American soldiers.

U.S. officials confirmed that many troops were moved to hotels and remote workspaces after Iranian strikes rendered numerous bases partially or fully uninhabitable, allowing some personnel to continue operations "remotely." Critics, including human rights groups like Amnesty International, have raised concerns that placing troops in civilian hotels may violate international humanitarian law by endangering surrounding populations.

Missile Interceptor Stocks

Missile interceptors have been a cornerstone of U.S., Israeli, and Gulf Arab defenses against Iran's retaliatory barrages in Operation True Promise 4. These systems, primarily U.S.-made Patriot (PAC-3 MSE), Israel’s Arrow-2/3 and David's Sling, and ship-based Aegis, use hit-to-kill kinetic energy or proximity-fused warheads to destroy incoming ballistic missiles, cruise missiles and drones in flight.

Early in the opening stages of the conflict, defenders relied on high-volume saturation intercepts, firing multiple expensive interceptors per threat. Each THAAD (Terminal High Altitude Area Defense) or Patriot round costs millions while many Iranian drones cost tens of thousands, creating a severe cost-imbalance that rapidly depleted regional stockpiles, with some Gulf states reportedly using 40–87% of their Patriot inventory in the first weeks.

THAAD has played an outsized role as the upper-tier system optimized for short- to intermediate-range ballistic missiles. Deployed in Israel, the UAE, Saudi Arabia, Jordan, and supported by U.S. batteries, THAAD's AN/TPY-2 radar detects threats at long range and guides Talon interceptors for exo-atmospheric "hit-to-kill" engagements.

In the current war it has achieved reported interception rates above 90% in some sectors, especially protecting UAE energy sites and Israeli airspace, but Iran has deliberately targeted its radars, claiming strikes on at least four, including Jordan's Muwaffaq Salti base. This has degraded coverage and forced the U.S. to relocate assets from elsewhere like South Korea. Stockpile strain is acute: the U.S. has expended roughly a quarter of its total THAAD inventory in just weeks, with each interceptor costing over $12 million and production rates still lagging far behind consumption.

Furthermore, Iranian strikes have successfully damaged or destroyed key AN/TPY-2 radars integral to U.S. THAAD missile defense systems in both Jordan and Saudi Arabia. In Jordan, Iranian missiles or drones hit the radar at Muwaffaq Salti Air Base during the opening days of major retaliatory operations. Satellite imagery from CNN and other outlets showed blackened debris, impact craters, and a heavily damaged or destroyed AN/TPY-2 radar unit, which U.S. officials confirmed as a roughly $300–500 million loss. This radar serves as the primary long-range sensor and fire-control component for the THAAD battery, significantly degrading high-altitude ballistic missile detection and interception capabilities in the northern Gulf/Israel corridor until replacements could be rushed in.

In Saudi Arabia, strikes targeted the Prince Sultan Air Base (southeast of Riyadh), damaging another AN/TPY-2 radar and associated THAAD-linked equipment. Satellite images revealed charring, structural damage and debris consistent with precision hits on the radar installation, with reports of at least one U.S. serviceman killed in related strikes. These attacks, part of Iran's broader campaign against U.S. and allied air-defense infrastructure, aimed to "blind" the networked missile shield by knocking out the expensive, high-value radars rather than the launchers themselves. The losses forced the U.S. to accelerate redeployments and replacements while increasing pressure on remaining Patriot systems.

Iran has deliberately shifted from high-volume saturation barrages to smaller, more selective salvos, resulting in a sharply declining daily fire rate but a rising penetration rate. In the opening days of major exchanges, Iran launched 100+ missiles per wave in an attempt to overwhelm layered defenses; by early-to-mid March 2026 the pace dropped dramatically, yet analysts observed higher success rates against high-value targets such as Gulf energy facilities.
