Tehran’s new power brokers
A wave of assassinations rebuilt Iran’s leadership from the top down, leaving a severely wounded supreme leader and a security establishment now calling the shots. Tehran, however, isn’t saying who is actually in charge. The silence is part of the narrative; who are the country’s power players?
Earlier this month, Iranian state media did something it had never done before.
Mehr News, an outlet controlled by the country’s Islamic Development Organization, released a video titled “First Images of the Leader,” showing Supreme Leader Mojtaba Khamenei addressing a small group of students. The footage was undated. It came, however, days after Israeli outlets reported the 56-year-old cleric was in “extremely critical condition,” and it appears to have done little to settle the question consuming Iran’s political class: is anyone actually running the country right now.
The clip echoed a similar undated video IRIB released in March, showing Khamenei teaching religious sciences. President Masoud Pezeshkian acknowledged this week that reaching him has been “very difficult,” though he described their last exchange as constructive.
Multiple sources close to Pezeshkian’s administration told IranWire that no cabinet minister has met with Khamenei since the February 28 strike that killed his father, Ali Khamenei, and that officials “would not be surprised” to hear news of his death.
Iranian authorities have repeatedly denied he’s incapacitated. But the man now holding life-tenure authority over Iran’s armed forces, judiciary and clerical establishment hasn’t spoken publicly, delivered a sermon, or appeared unedited on camera since taking the post in March.
“The main issue for U.S. policymakers — especially any president — is whether the new leadership in Iran, or any leadership we can currently anticipate, is likely to depart materially from the strategic policies of the previous leadership,” Norman Roule, a former CIA officer who spent 34 years managing programs related to Iran and the Middle East, tells The Cipher Brief. “The evidence to date suggests no fundamental break.”
The vacuum at the top didn’t stay empty for long.
A Leadership Rebuilt Through Killings
The cascade began on February 28, when a joint U.S.-Israeli strike killed longstanding leader Ali Khamenei along with Mohammad Pakpour, the Islamic Revolutionary Guard Corps’ commander-in-chief, and a string of other senior officials. An interim leadership council, made up of Pezeshkian, judiciary chief Gholamhossein Mohseni-Ejei and cleric Alireza Arafi, held the state together for less than a week before the Assembly of Experts named Mojtaba Khamenei as Iran’s third Supreme Leader on March 8.
The choice was unusual on its face. The Islamic Republic was founded on the overthrow of hereditary monarchy, yet its clerical establishment had just installed the son of the man he replaced. Mojtaba lacked the religious credentials typically required of a Supreme Leader. He was widely regarded as a hojatoleslam, a mid-ranking cleric, rather than an ayatollah — yet he had spent nearly two decades as his father’s gatekeeper and enjoyed deep loyalty inside the Revolutionary Guard.
President Trump, who had labeled him “unacceptable” during the war, later told Fox News that the succession was not one his own father had wanted, adding, “their leadership is gone, their second leadership is gone, now their third leadership is in trouble.”
Roule, however, cautions against reading the new bench as a break from what came before it. Most of Iran’s current leaders, he notes, “rose within institutions shaped by Ali Khamenei and were trusted, promoted, or shaped within, and by the system he developed over years of rule.”
Roule points to the generational math: Pezeshkian, Mohsen Rezaee and Ali Reza Zolghadr were about 25 years old at the time of the 1979 revolution; Ahmad Vahidi was 21; Mohammad Bagher Ghalibaf and Sadeq Amoli Larijani around 18; Mojtaba Khamenei just 10.
“For this group, the 1979 Revolution remained the ideological foundation of the system, but the Iran-Iraq War and the post-2003 campaign for regional influence were more important professional experiences,” Roule explains. “Most are veterans of the Iran-Iraq War or were directly shaped by it.”
The current command of the Islamic Revolutionary Guard Corps has followed the same brutal pattern.
Amir Ali Hajizadeh, head of the Guard’s aerospace force, was killed in a strike in June 2025. Pakpour, who had succeeded Hajizadeh’s predecessor Hossein Salami, was killed at the outset of the U.S.-Israeli campaign in February. His successor, Ahmad Vahidi, a Quds Force founder and former interior minister with an Interpol red notice tied to the 1994 AMIA bombing in Buenos Aires, was formally installed as commander-in-chief on March 1.
Unverified reports of Vahidi’s own death circulated in Tehran in late May and again in early June; Iranian, Israeli or American officials have confirmed none, and Vahidi continues to be listed as the IRGC’s active chief.
A Crackdown That Fits the Moment
The uncertainty at the top has coincided with a sharp rise in executions and threatened executions, months after the January protests that shook the regime.
Austin Sarat, a professor of jurisprudence and political science, says the war and the unrest have compounded each other rather than one driving the other alone.
“The protests and the war have fueled — it’s like putting a little bit of an accelerant into something that’s already pretty flammable,” Sarat tells The Cipher Brief. “The protests were, I think, much more trigger than the war itself. The war has just provided yet another excuse, because it’s jacked up nationalist fervor.”
Sarat is skeptical that outside pressure, including past White House rhetoric threatening consequences over executions, has had much bearing on Tehran’s calculus.
“The administration has said nothing about human rights abuses, let alone execution practices around the world,” he says, underscoring that any outside leverage is more likely to come from Europe than Washington. He views the surge itself as a familiar survival tactic for a leadership still finding its footing.
“It’s not a kind of unfamiliar tactic for a regime new to power to want to flex its muscle and terrorize the population,” he observes. “This is a survival moment, and they are going to do what they are going to do to preserve the essential character of their regime.”
The Guard Consolidates Around the Vacuum
With the younger Khamenei largely unseen, the Revolutionary Guard didn’t sit on its hands. It moved fast, filling top posts through official decrees.
Along with Vahidi, the Supreme Leader’s office named Mostafa Izadi as deputy IRGC commander, Ali Azmaei to head the IRGC Navy and Hossein Taeb to lead the Basij paramilitary force, filling six senior military posts vacated by wartime deaths.
Mohsen Rezaee, who commanded the IRGC from 1981 to 1997, was separately appointed as the Supreme Leader’s representative on the Supreme National Security Council. This post opened up, according to Rose Kelanic, director of the Middle East Program at Defense Priorities, after Zolghadr was pushed out.
Kelanic argues the reshuffle amounts to more than a personnel change.
“Mojtaba Khamenei’s role appears to be that of a figurehead and potential scapegoat, enjoying far less authority than his father, whom he replaced,” Kelanic tells The Cipher Brief. “The real power rests with Ghalibaf, Vahidi and Rezaee, who are all career IRGC officers, which functionally means that Iranian government authority has shifted even further from civilian control to military control.”
That shift, she continues, carries its own risk for any settlement with Washington.
“When military leaders assume control as heads of state in wartime, they tend to make worst-case assumptions about adversaries’ intentions, view compromise as weakness, and favor offensive military strategies over defensive ones,” Kelanic points out.
Roule, meanwhile, frames the Guard’s rise in institutional rather than personal terms, and says the war has widened rather than preserved its reach. Estimates of how much of Iran’s economy the IRGC touches “vary widely — roughly from a fifth to a third,” he says, depending on whether one counts only directly controlled firms or also affiliated holding companies, pension funds and sanctions-evasion networks.
“A better way to think about the IRGC is not simply as a military organization with commercial interests, but as a central actor in a state-security-economic network,” Roule notes.
Ghalibaf’s Quiet Climb to the Center
The other figure benefiting from the uncertainty at the top is Ghalibaf, the parliament speaker and former IRGC commander who has spent the war years turning what is traditionally a legislative post into something closer to a shadow foreign ministry.
Ghalibaf, a two-time presidential also-ran who trailed Pezeshkian in the first round of the 2024 election, has emerged as Tehran’s principal interlocutor in the indirect talks with Washington, serving simultaneously as Iran’s special envoy to China and as a bridge between the political and military-security establishments that Pezeshkian, a physician by training with no roots in the security services, has struggled to command.
Parliament re-elected Ghalibaf to a seventh consecutive term as speaker in late May, with 235 of 271 votes cast, as reports circulated of friction between Pezeshkian and the new Supreme Leader’s office. Judiciary chief Mohseni-Ejei congratulated Ghalibaf on the vote by calling him a “tireless and battle-hardened jihadist leader” who had waged jihad “both in the field and in diplomacy” during the war.
Roule warns against reading Ghalibaf’s prominence as a formal power grab.
“His current prominence should not be confused with general supremacy over Pezeshkian,” he says. “Pezeshkian nonetheless remains president, heads the executive branch, and formally chairs the Supreme National Security Council. There is no evidence that Ghalibaf has assumed any of the presidency’s general constitutional authorities.”
His influence, Roule highlights, “is best understood as issue-specific power produced by circumstances, his political standing, longstanding IRGC relationships, and wartime delegation.”
Who Actually Holds the Reins
What emerges from the past five months of conflict, however, is a regime governed less by the clerical hierarchy that has defined the Islamic Republic since 1979 than by an overlapping wartime trio.
A Supreme Leader whose authority is formally absolute but whose physical capacity to exercise it remains unverified. An IRGC command structure rebuilt twice over through assassination and now operating with wide latitude, alongside a parliament speaker who has converted legislative standing into genuine diplomatic weight.
Still, Roule sees continuity as the most likely outcome even if Mojtaba’s health worsens further.
“If Mojtaba Khamenei becomes seriously incapacitated or dies, the most likely outcome absent a successful mass uprising or a major elite fracture is continuity rather than reversal on the issues of greatest concern to the United States,” he says. “The IRGC would remain a central power center, and the system has constitutional procedures for interim leadership and selection of a successor.”
He also points out that if Mojtaba’s death were tied to the war, “the state would almost certainly use a martyrdom narrative to reinforce regime legitimacy and resistance.”
Kelanic is less sanguine about what that continuity means for diplomacy. Iran, she stresses, will also grow harder to negotiate with simply because power is now split among rivals rather than concentrated in one office, leaving Washington without a clear address for any deal.
“The IRGC’s strengthened rule over a weaker civilian leadership makes reaching a peace deal harder,” Kelanic adds, “which is one of many ways the Iran War has backfired.”
