The 88-member clerical body constitutionally tasked with selecting Iran's next Supreme Leader cannot convene — its Qom headquarters was hit directly.

Key takeaway

The destruction of the Assembly of Experts eliminates Iran's only constitutional mechanism for selecting a new Supreme Leader, transforming a leadership vacancy into a systemic state crisis.

The Qom headquarters of the Assembly of ExpertsIran's 88-member clerical body constitutionally tasked with selecting and supervising The Supreme Leader — was struck directly in the US-Israeli operations. The building's destruction, combined with the confirmed deaths of senior officials, means the body cannot convene to fulfil its sole constitutionally mandated function: choosing Khamenei's successor.

Iran's 1979 constitution provides no alternative mechanism. No provision addresses the simultaneous loss of The Supreme Leader, the defence minister, the IRGC commander, and the selection body itself. Khomeini's constitutional architecture assumed institutional continuity — that the Assembly would outlive any individual leader and manage succession through deliberation among its clerical members. That architecture required the Assembly to exist as a functioning body.

The last Supreme Leader transition, from Khomeini to Khamenei in June 1989, took the Assembly two days to complete. Even that was a contested process. Khamenei was a compromise candidate — a mid-ranking cleric elevated because the originally designated successor, Hossein-Ali Montazeri, had been removed from the succession line months earlier after criticising the government's mass executions of political prisoners. Khamenei lacked the senior clerical credentials traditionally required for the role and spent years consolidating authority against more established ayatollahs.

The IRGC controls an estimated $100 billion economic empire spanning construction, telecommunications, energy, and financial services. Without the Assembly to provide constitutional legitimacy to a new leader, the question of who commands that empire — and the coercive apparatus of the state — will be resolved by power dynamics rather than legal procedure. Whether the IRGC consolidates under a single commander or fractures along factional lines — Quds Force against ground forces, hardliners against officers who recognise the need to accommodate the fourteen-month protest movement — will define Iran's political trajectory.

Deep Analysis

In plain English

Iran has a special body of 88 senior clerics whose only real job is to pick the Supreme Leader. Their headquarters in the holy city of Qom was hit in the strikes. Without this body, there is no legal way under Iran's constitution to choose a new leader. The last time a Supreme Leader died — in 1989 — this body met within hours and picked a replacement in two days. Now the body itself has been destroyed along with the leader. Iran's political future will be decided by whoever has the most power, most likely the Revolutionary Guards, rather than by any constitutional process.

Deep Analysis
Synthesis

The destruction of the Assembly of Experts is the structural complement to Khamenei's death. Killing the leader created a vacancy; destroying the selection body made the vacancy permanent under existing law. The Islamic Republic's 1979 constitution is now inoperable at its most fundamental level. This is not a succession crisis — it is the end of a constitutional system. Whatever political order emerges in Iran will not be a continuation of the Islamic Republic as Khomeini designed it.

Root Causes

The targeting of the Assembly building indicates that the US-Israeli operation was designed as a comprehensive decapitation campaign — eliminating not only individual leaders but the institutional mechanism for replacing them. This target selection implies a strategic intent to prevent the Islamic Republic from reconstituting itself under its existing constitutional framework. Whether this was intended to force a regime change or simply to maximise strategic disruption is a question of operational intent that has not been stated publicly.

Escalation

The destruction of the Assembly is an escalatory act beyond the killing of individual leaders because it forecloses the constitutional path to political reconstitution. A state with a dead leader can select a new one; a state with both a dead leader and a destroyed selection body has no lawful path forward. This raises the stakes of the power vacuum: any authority that emerges will be extra-constitutional, which makes it harder for external actors to negotiate with and harder for Iranian citizens to accept.

What could happen next?
  • Consequence

    No constitutional mechanism exists to select a new Supreme Leader, meaning any successor will derive authority from power rather than legal procedure.

    Immediate · Assessed
  • Risk

    The IRGC's $100 billion economic empire has no legitimate governance structure above it; control of these assets becomes a prize in any internal power struggle.

    Short term · Assessed
  • Opportunity

    For Iran's protest movement, the destruction of the theocratic succession mechanism removes the institutional pathway for restoring clerical rule, potentially opening space for a different political settlement.

How this affects the world
  • Iran

    The constitutional order of the Islamic Republic is effectively dissolved. The IRGC is the only institution with the organisational capacity and coercive force to govern; its internal dynamics will determine whether Iran fragments or consolidates under military rule.

  • Shia religious world

    Qom is the centre of Shia clerical authority alongside Najaf in Iraq. The destruction of the Assembly building in Qom shifts the centre of gravity for Shia political-religious authority toward Najaf and Grand Ayatollah Sistani's establishment.

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
