The Power Vacuum: Who Actually Rules Iran After the Decapitation

Article 111 of the Iranian constitution is specific. If the supreme leader is unable to fulfill his duties, a temporary council takes over: the president, the head of the judiciary, and a faqih designated by the Guardian Council. This provision was drafted for precisely the kind of crisis Iran now faces. It has not been activated. No council has been formed. No official statement has acknowledged the mechanism's relevance. The constitution of the Islamic Republic, four weeks into a war that killed the man at its center, has become decorative.

What has replaced it is a contest between two power centers that operate outside the constitutional framework entirely. One is Mojtaba Khamenei, the son of the slain supreme leader, who holds the title but has not been seen exercising the authority it confers. The other is the Islamic Revolutionary Guard Corps, whose commanders control the economy, direct the military, and increasingly fill the decision-making space that the religious leadership has vacated. The question of who actually rules Iran is not theoretical. It determines whether the war can end through negotiation or only through exhaustion.

What the Constitution Says

Iran's constitutional framework for supreme leader succession is not ambiguous. Article 107 states that after Ruhollah Khomeini, the leader is to be elected by the Assembly of Experts, an 88-member body of senior clerics. Article 109 requires the leader to possess competence in Islamic jurisprudence sufficient for issuing fatwas, alongside political and social insight and administrative ability. Article 5 grounds the entire system in velayat-e faqih, the guardianship of the Islamic jurist, which means the supreme leader's authority derives not from popular mandate alone but from religious qualification.

The Assembly of Experts last held scheduled elections in March 2024. Its members serve eight-year terms. The body's constitutional role is to appoint, supervise, and if necessary dismiss the supreme leader. In normal circumstances, the assembly would convene upon the death of the leader, deliberate, and elect a successor based on the qualifications outlined in Article 109. The Guardian Council, whose six clerical members were appointed by Ali Khamenei and whose six jurists were nominated by the head of judiciary, serves as a vetting body that determines who may stand for election.

None of this has happened. The Assembly of Experts has not convened publicly. The Guardian Council has not issued procedural guidance. The constitutional mechanism for succession remains inert while a new leader operates under a title conferred through channels that no Iranian legal scholar has publicly explained.

The Son Who Was Never Qualified

Mojtaba Khamenei's ascension to the position of supreme leader inverts the logic of the system his father spent three decades building. The Islamic Republic was designed to prevent dynastic succession. Khomeini explicitly rejected hereditary rule as a pre-revolutionary relic. Ali Khamenei himself was an unconventional choice in 1989, elevated despite holding only the rank of hojatoleslam rather than ayatollah, a theological deficit that required a constitutional amendment removing the requirement for marja (source of emulation) status. Even with that amendment, the expectation was that the leader would possess serious jurisprudential credentials.

Mojtaba holds the rank of hojatoleslam. He has no significant published religious scholarship. His career consisted primarily of managing his father's office, overseeing financial networks connected to the supreme leader's vast institutional holdings, and maintaining relationships with senior IRGC commanders. He was widely understood within Iran's political class as a gatekeeper and financial manager, not a political figure in his own right.

U.S. and Israeli intelligence agencies believe Mojtaba was wounded during the war, though the specifics remain unconfirmed. What is confirmed by multiple Western intelligence assessments is that he has not appeared in public since assuming the title. For a position whose legitimacy depends on the visible exercise of religious and political authority, invisibility is functionally equivalent to incapacitation.

The theological problem compounds the political one. Velayat-e faqih requires a qualified jurist at the apex of the state. Mojtaba's jurisprudential standing does not meet the threshold set by Article 109, even under the 1989 amendment that lowered the bar. Senior clerics in Qom, already skeptical of his qualifications before the war, have no institutional incentive to grant retroactive legitimacy to a figure who bypassed the Assembly of Experts entirely.

The IRGC's Constitutional Ambiguity

The Islamic Revolutionary Guard Corps exists in a constitutional gray zone. Article 150 of the constitution defines its role as "guarding the Revolution and its achievements," a mandate broad enough to justify nearly any exercise of power. The IRGC was designed as a parallel military force, separate from the regular army (Artesh), with its own ground forces, navy, air force, and the Quds Force for external operations. It answers constitutionally to the supreme leader, who serves as commander-in-chief under Article 110.

When the supreme leader is absent or weakened, the IRGC's chain of command loses its apex. In theory, this should reduce the Guards' authority. In practice, the opposite has occurred. American officials, speaking on condition of anonymity to describe intelligence assessments, report that IRGC hardliners have become more influential than the religious leadership nominally in charge of the state. This assessment aligns with a structural reality that predates the war: the IRGC has spent decades building an institutional power base that does not depend on any single leader's patronage.

The Guards operate their own intelligence service, separate from the Ministry of Intelligence. They run their own judiciary within the military system. They control border security, large portions of Iran's missile program, and the entirety of the proxy network that extends from Lebanon through Iraq to Yemen. Each of these functions continued operating after the leadership compound strike because each has its own command structure, logistical chain, and institutional memory. The IRGC is not a bodyguard force that collapses without its principal. It is a state within a state, and the disappearance of the formal state has only made the shadow state more visible.

The Economic Lever

The IRGC's political power is inseparable from its economic position. Estimates of the Guards' share of the Iranian economy range from 20 to 50 percent, a wide band that reflects the difficulty of tracing ownership through shell companies, bonyads (charitable foundations), and front organizations. The US Treasury's Office of Foreign Assets Control has designated hundreds of IRGC-linked entities, providing a partial but instructive map of the empire.

The Khatam al-Anbiya Construction Headquarters, the IRGC's engineering arm, has received hundreds of government contracts in sectors ranging from oil and gas development to highway construction and dam building. IRGC-linked entities operate in telecommunications, automotive manufacturing, and import-export. In a sanctions economy where legitimate banking channels are largely closed, the organizations that control informal trade routes and smuggling networks hold disproportionate economic power.

The war has intensified this dynamic. Iran's rial, which had already collapsed over 97 percent since 2018, falling from roughly 42,000 to 1,600,000 per dollar, faces further pressure from wartime disruption. Inflation stood at approximately 43 percent by IMF estimates before the war began, with food prices having nearly doubled between January 2025 and January 2026. Under these conditions, the entity that controls supply chains controls loyalty. Reconstruction contracts will flow through IRGC-connected firms. Import licenses for essential goods will require IRGC cooperation. Economic crisis does not weaken the Guards; it makes them indispensable.

This is a pattern visible across sanctioned states. In Iraq under Saddam Hussein, the Republican Guard's economic privileges expanded with each round of sanctions. In North Korea, the Korean People's Army's economic role grew as civilian institutions atrophied under international isolation. The IRGC follows this same trajectory, with the added accelerant of wartime destruction creating new dependencies.

The 1981 Parallel

The Islamic Republic has experienced one previous crisis in which military-revolutionary authority and civilian governance collided. In June 1981, the first elected president, Abolhassan Bani-Sadr, was dismissed by Ayatollah Khomeini after months of escalating conflict over military appointments and the direction of the Iran-Iraq War. Bani-Sadr had attempted to assert civilian control over the armed forces, challenging the Islamic Republican Party and the nascent IRGC's influence over military operations. He lost. By July 1981, he had fled to France.

The 1981 crisis established a precedent that has shaped Iranian politics for four decades: when civilian and military-clerical authority conflict, the military-clerical side wins, provided it has the supreme leader's backing. Khomeini's intervention was decisive. He served as the arbiter between competing factions, and his verdict was final.

The current crisis differs in a structural way that makes the 1981 parallel both relevant and insufficient. In 1981, the supreme leader was the arbiter. Today, the arbiter position itself is compromised. There is no Khomeini figure capable of resolving the tension between the nominal supreme leader and the institutional power of the IRGC. Mojtaba Khamenei, even if physically capable of governing, lacks the religious authority, political experience, and personal relationships that would allow him to discipline the Guards the way his father could. Ali Khamenei spent three decades carefully balancing IRGC ambition against clerical authority, playing commanders off against each other, rotating leadership, and ensuring no single faction within the Guards became powerful enough to challenge him. That balancing act died with him.

What We Know, What We Do Not

An honest assessment of the current intelligence picture requires distinguishing between what is confirmed, what is claimed by specific sources, and what remains unknown.

Confirmed by multiple Western intelligence agencies: Ali Khamenei was killed in the initial leadership compound strike at the beginning of the war. Mojtaba Khamenei has been named as his successor. He has not appeared in public since assuming the title. Iran's security and military agencies continue to function at an operational level. Several dozen Iranian leaders and their deputies have been killed since the war began.

Claimed by U.S. and Israeli intelligence, not independently confirmed: Mojtaba Khamenei was wounded during the war. IRGC hardliners have become more influential than the religious leadership. Surviving leaders are unable to meet in person and reluctant to communicate electronically for fear of interception.

Unknown: Which specific IRGC commanders now hold effective decision-making power. Whether the Assembly of Experts has attempted to convene, either formally or informally. Whether Mojtaba Khamenei is physically capable of exercising authority. What, if any, communication exists between Mojtaba and IRGC leadership. Whether any faction within the regime possesses the authority to negotiate on behalf of the entire Iranian state.

The gap between what Western intelligence claims and what can be independently verified is significant. Much of the current assessment relies on signals intelligence and satellite imagery rather than human sources inside the Iranian power structure. The fog of war applies to intelligence assessments as much as to battlefield reporting.

The Governance Gap

The distinction between operational continuity and strategic capacity is central to understanding Iran's current state. A government can continue to function at the routine level while being incapable of strategic decision-making. Police officers patrol streets. Bureaucrats process documents. Military units follow existing orders. Power plants generate electricity. These functions do not require strategic direction from the top; they follow established procedures and institutional momentum.

What requires central authority is precisely what the current situation demands: deciding whether to negotiate, on what terms, with what concessions. Deciding whether to escalate military operations or de-escalate. Deciding whether to accept a ceasefire framework and binding the entire state apparatus to that decision. These are functions that only a legitimate, recognized, and empowered leadership can perform.

The Trump administration has pressed for a quick deal, but the premise of that demand assumes a counterpart with the authority to accept or reject terms. Western officials briefed on intelligence assessments acknowledge that Iranian negotiators may not know what their government is willing to concede because the answer to that question requires a decision-maker, and it is unclear who that is. The irony is structural: the decapitation strikes succeeded in eliminating Iran's leadership but may have also eliminated the capacity for the surrender or agreement that the strikes were intended to compel.

What Comes Next

Three trajectories are visible, each with different implications for the war's resolution.

In the first, Mojtaba Khamenei recovers, appears publicly, and consolidates authority by securing IRGC acquiescence and at least partial clerical legitimation from Qom. This scenario requires him to demonstrate both physical capability and political skill, neither of which has been evidenced so far. If it occurs, a negotiating counterpart exists, though the terms he could accept are constrained by hardliners who have gained power during his absence.

In the second, the IRGC formalizes its control, either through a military-dominated council or by installing a compliant supreme leader who serves as a figurehead while Guard commanders make decisions. This has precedents in the region, from Pakistan's military governments to Egypt's post-2013 structure. It would produce a negotiating counterpart, but one whose priorities center on institutional survival rather than the broader national interest the supreme leader is constitutionally mandated to represent.

In the third, fragmentation continues with no single authority emerging. Different IRGC factions, clerical networks, and surviving civilian officials operate in parallel, occasionally cooperating but unable to produce a unified strategic decision. Post-2011 Libya offers the starkest version of this outcome. Under this scenario, no negotiated end to the war is possible because no one has the authority to negotiate for all of Iran.

Four weeks after the strike that killed Ali Khamenei, the Islamic Republic's institutions have not responded as the constitution prescribes. The Assembly of Experts has not convened. Article 111 has not been activated. The Guardian Council has not issued guidance. What exists instead is a contest between an invisible leader without credentials and a military-economic institution that was never designed to govern but increasingly has no alternative. The question the United States needs answered before any deal is possible is not what Iran is willing to concede. It is whether anyone in Tehran has the authority to concede anything at all.
