The death of Iranian Supreme Leader Ali Khamenei—along with more than 40 senior regime officials—has created a significant power vacuum within Iran. However, Tehran likely remains capable of quashing any uprisings due to its sprawling network of local security forces, according to former U.S. officials and regional analysts.
Israeli officials have stated their aim is regime change, though it remains unclear whether the ongoing U.S.-led military operations are oriented toward that goal rather than a more nuanced shift in power dynamics.
Ray Takeyh, who served as an adviser on Iran at the State Department, noted Khamenei “is the only leader they have ever known.” With 60 percent of the country under 30 years of age, Takeyh described the death as discombobulating and warned protests are likely to return.
Former U.S. Iran envoy Elliott Abrams emphasized that Khamenei’s replacement cannot match his influence: “They can find a substitute for most officials, but not for Khamenei. Whoever succeeds him will not truly be supreme leader, able to give unquestioned instructions to the Army and IRGC. He will be a far smaller figure, politically and spiritually.”
Analysts warn Iran’s regime may struggle with internal cohesion following Khamenei’s death. The Islamic Revolutionary Guard Corps (IRGC) and its Basij militia remain central to repression, though Iranian foreign minister Abbas Araghchi acknowledged military divisions have become “independent and [somewhat] isolated.” Former Pentagon official Michael Rubin stressed that control of local arms depots—not Tehran—determines security forces’ effectiveness.
Former CIA officer Reuel Marc Gerecht, a resident scholar at the Foundation for Defense of Democracies, called Khamenei’s death “a shock to the Islamic Republic” but expressed skepticism about prolonged paralysis: “I don’t think it has to be clear for the Islamic Republic in its dilapidated state to keep functioning.”
Israeli intelligence officials confirmed operations targeting over 40 key Iranian figures within minutes. Brig. Gen. Shlomi Binder of the Israel Defense Forces stated: “We are sending a clear message to our enemies: There is nowhere we will not find you.” The targeted list includes senior cleric Alireza Arafi, Chief Justice Gholam-Hossein Mohseni-Ejei, and President Masoud Pezeshkian—each with distinct roles in Iran’s interim leadership.
Though renewed protests have yet to grip Iran since President Donald Trump launched Operation Epic Fury on Saturday, analysts predict a wave of popular unrest once bombings subside. Takeyh warned: “There will be an aftershock of popular revolt once the bombings slow down. The problem is that the regime may have gotten its footing sufficiently by then to react strongly.”
