Power Structure
Iran’s political system concentrates power at the top of a clerical-military hierarchy. The Supreme Leader held final authority over armed forces, foreign policy, and judiciary. The assassination of Ali Khamenei on February 28, 2026 has created the most significant leadership vacuum in the Islamic Republic’s history.
The Assembly of Experts is constitutionally responsible for designating a successor, but the assembly itself is a body of senior clerics subject to IRGC influence and external pressure. No successor has been publicly confirmed. Operational military and diplomatic decisions are being made collectively, with Parliamentary Speaker Mohammad Bagher Ghalibaf leading the Iranian delegation in Islamabad talks — suggesting the legislature is temporarily filling a vacuum in external-facing authority.
The IRGC retains full operational control of missile forces, naval asymmetric capabilities, and the Hormuz closure operation. The IRGC’s capacity to act independently of civilian direction has long been substantial; under current conditions it is effectively unchallengeable domestically.
Recent History
Iran entered 2026 in an acute domestic crisis. In January 2026, Iranian security forces conducted a violent crackdown on the largest wave of popular protests since 1979, reportedly resulting in thousands of civilian deaths. The repression triggered explicit US threats of military action and accelerated the buildup that preceded the February 28 strikes.
Iran had previously exchanged missile strikes with Israel in 2024 and participated in the Twelve-Day War in June 2025, during which US airstrikes destroyed Iranian nuclear sites. The nuclear programme was therefore already severely degraded before the current war began, complicating Iran’s strategic deterrence calculus.
Strategic Position
Iran’s primary leverage has been geographic and economic rather than conventional military. Control of the Strait of Hormuz — even the credible threat of its disruption — gives Iran asymmetric power over global energy markets disproportionate to its conventional military capability. The IRGC’s maritime harassment strategy (sea mines, drone attacks, speed boat swarms) does not require high-end military technology to be economically devastating.
China is Iran’s most important external relationship. China purchases the majority of Iranian oil exports under sanctions-evasion arrangements, providing Tehran with the hard currency to survive pressure. In the current conflict, China has provided diplomatic protection at the UN Security Council and facilitated continued tanker passage under the “China-owner” signalling arrangement.
Iran’s proxy network — Hezbollah in Lebanon, Houthi forces in Yemen, Popular Mobilization Forces in Iraq — provides additional pressure levers against US allies and forces, though the network’s reliability as an instrument of Iranian state policy (rather than autonomous actors) varies considerably.
Nuclear Dossier
Iranian nuclear facilities were severely damaged in the June 2025 Twelve-Day War. Current enrichment capacity is unknown. The US is demanding nuclear programme termination as a condition of any peace settlement. Iran has not confirmed the status of remaining enrichment capability and is unlikely to do so.
Assessment
The killing of Khamenei has not collapsed the Islamic Republic — the system was designed for institutional continuity — but it has produced an unprecedented leadership legitimacy problem at the worst possible moment. Iran is fighting a war without a supreme commander, managing an economy under maximum pressure, and conducting diplomacy through a parliamentary speaker with unclear authority. Its negotiating position is weakened not by military losses but by internal incoherence. The regime’s survival calculation has always prioritized continuity over resolution; that calculus has not changed, but the actors making it are less certain than at any point since 1989.
