Iran’s Succession Crisis Could Make Its Nuclear Policy More Bargainable

The succession question is not simply vacant

Iran is holding multiday funeral events for Ali Khamenei, with Al Jazeera reporting that his body reached Qom after major Tehran processions. The basic facts matter: Khamenei was killed on February 28 at the start of the U.S.-Israel war on Iran, and AP has reported that Mojtaba Khamenei was selected as supreme leader in March.

That makes the common “who succeeds Khamenei?” framing too loose. Formally, the answer appears to be Mojtaba. The unresolved issue is whether he can exercise authority in a visible, durable way during a war and under assassination risk. Al Jazeera has reported that Mojtaba has not appeared publicly since the February strike and was absent from family funeral events, with officials citing security concerns and others speculating about injury.

Iran is not institutionally empty. Its constitution gives the Assembly of Experts the job of appointing a supreme leader, and Article 111 provides for temporary leadership by the president, judiciary chief, and a Guardian Council jurist if needed. But procedure is not the same as political settlement. Mojtaba lacks his father’s revolutionary biography and decades of accumulated authority. That makes other institutions — the IRGC, judiciary, presidency, Supreme National Security Council, Guardian Council, and clerical networks — more important, not less.

Why this could make nuclear policy more negotiable

The lazy assumption is that a weaker wartime leader must escalate to prove toughness. That is possible, but it is not the only plausible path. A less-established supreme leader may also need a clearer bargain among Iran’s power centers: what is traded, what is preserved, and who signs off.

The nuclear issue is where that matters most. Reuters reported that IAEA chief Rafael Grossi said inspections would proceed under an interim U.S.-Iran accord, while Iranian Deputy Foreign Minister Kazem Gharibabadi said access to attacked nuclear sites and nuclear material would depend on a final agreement and sanctions relief. That is not capitulation. It is conditional bargaining.

The hard unresolved fact is material control. The IAEA estimated Iran had 440.9 kg of uranium enriched up to 60% before earlier attacks, close to the roughly 90% weapons-grade threshold, and has not verified the fate of that stockpile. A government that wants sanctions relief or a war-termination framework will eventually have to define what inspectors can see at sites such as Fordow, Natanz, and Isfahan, and what happens to high-enriched material.

That is where succession can cut against the standard escalation script. Mojtaba may need the IRGC’s support, but the IRGC also needs a functioning economy, coherent command, and a survivable deterrent posture. The judiciary and Supreme National Security Council matter because they can help turn a political decision into enforceable access rules, detention policy, shipping policy, and negotiating mandates. Al Jazeera’s report that Judiciary Chief Gholam-Hossein Mohseni-Ejei was reappointed during the funeral period is relevant for that reason, not as inside-baseball ceremony.

Hormuz is the practical pressure point

The same bargaining problem applies to the Strait of Hormuz. Reuters and AP reported a tanker was hit by a projectile near Limah, Oman, on July 7, and Reuters said oil prices rose about 1.5% after the incident. Attribution remains uncertain; the incident has not been officially claimed by Iran. But markets do not need courtroom proof to price risk.

This is why the succession story matters outside Iran. A leadership transition during war affects nuclear inspections, sanctions relief, oil shipping, U.S. force posture, Gulf security, and Israel’s threat calculations. Funeral turnout does not prove unity. Mojtaba’s title does not prove command cohesion. And “hardliners escalate” is too crude to explain a system that may now need explicit bargains to keep itself operating.

The practical question is whether Iran’s new leadership can make a deal that its own institutions will obey. If it can, nuclear policy may become more bargainable. If it cannot, ambiguity over enriched uranium, site access, and Hormuz will remain the policy.
