Iran is facing a dilemma in how to respond to the killing of Hezbollah leader Hassan Nasrallah by Israel. Nasrallah was a close ally of Iran's supreme leader, Ayatollah Ali Khamenei, and his death has left Iran in a vulnerable position. Fissures have opened within the Iranian government, with conservatives calling for a forceful response and moderates advocating for restraint. Khamenei has assumed a calm and pragmatic posture, issuing restrained statements and pledging support for Hezbollah. Iran's response to this situation will have significant implications for the ongoing tensions in the Middle East.
