While Iran is likely to retaliate in some capacity — probably by continuing its trend of using proxy fighters to hit US or Israeli assets abroad — it has neither the military might nor political strength to enter its people into a full-scale war with the West. Israel and its allies have also already transported their citizens to safe zones and prepared their defense mechanisms, which means Iran has two choices: — play "small ball" or make a larger move and risk being crushed by a Western counterattack.
