Iran in Chaos After Supreme Leader Assassinated
Iran's Supreme Leader Ayatollah Ali Khamenei has been killed in a joint U.S.-Israeli operation, plunging the country into crisis. Explosions have rocked Tehran for a second day as Israel expands its campaign, while Iran has retaliated with missile strikes on Israel and Gulf states. Tehran has vowed "massive" revenge and says it will select a new leader in the next two days.
This is only the second time in the history of the Islamic Republic that a new supreme leader will be chosen. The last succession occurred in 1989 when the Assembly of Experts selected Ali Khamenei to follow the founder of the republic, Ayatollah Ruhollah Khomeini. That transition was completed within a day of Khomeini's death. The 88-member Assembly of Experts, a body of Islamic jurists, is constitutionally responsible for selecting the new supreme leader. Candidates for the assembly are vetted by the Guardian Council, whose members are themselves appointed directly or indirectly by the supreme leader, creating a tightly controlled selection process. The current assembly, elected in 2024, is chaired by Mohammad-Ali Movahedi Kermani. Until a new leader is chosen, a temporary council will assume his duties. This council is composed of the sitting president, Masoud Pezeshkian, the head of the judiciary, Gholamhossein Mohseni Ejei, and a cleric from the Guardian Council. This arrangement brings together different factions, with Pezeshkian considered a reformist and Mohseni Ejei a hardliner. The Islamic Revolutionary Guard Corps (IRGC) is expected to wield significant influence over the succession process. The IRGC has become a dominant force in Iran's military, economy, and politics, and any new leader will likely need their backing to govern effectively. In the wake of the assassination, the IRGC has vowed a "most ferocious offensive" against the U.S. and Israel. While the constitutional process is clear, the sudden nature of Khamenei's death creates a leadership vacuum that could trigger a power struggle among Iran's conservative, moderate, and reformist factions. The country has faced significant internal unrest in recent years, including widespread protests, which adds another layer of instability to this critical transition period. The supreme leader holds immense power in Iran's political system, acting as the commander-in-chief of the armed forces and having the final say on all major state matters. The position oversees the executive, legislative, and judicial branches of government, as well as key institutions like the Guardian Council and state media. Potential successors who have been discussed in the past include Khamenei's son, Mojtaba Khamenei, though there is opposition to a hereditary succession. Other names that have been mentioned include senior clerics and political figures, but the deliberations of the Assembly of Experts are held in secret. The assassination has created significant disarray within Iran's security and military structures, with some reports indicating disruptions in the chain of command. While some Iranians have reportedly celebrated the news, the government has declared 40 days of national mourning and promised a severe response.
