The U.S. position represents a necessary hardline stance to prevent Iran from developing nuclear weapons capability. Complete dismantlement of enrichment facilities is the only way to ensure regional security and prevent Tehran from potentially breaking out to nuclear weapons. Previous deals with sunset clauses and limited restrictions proved ineffective in containing Iran's nuclear ambitions.
Iran has legitimate rights to peaceful nuclear technology under international law and has paid a heavy price for this achievement. The demand for zero enrichment is unrealistic and politically motivated, as other nations are permitted to enrich uranium. Iran is willing to accept limitations and monitoring but cannot surrender its fundamental right to civilian nuclear technology.
