Iran has selected Mojtaba Khamenei, the son of the late Supreme Leader Ali Khamenei, as the country’s new supreme leader while the war with the United States and Israel continues. The succession is extraordinary not merely because it occurred under bombardment, but because the Islamic Republic was founded partly in opposition to hereditary monarchy. Choosing the previous leader’s son inevitably creates the appearance of dynastic succession inside a political system whose revolutionary legitimacy was built around rejecting the Shah. At the same time, American and Israeli strikes have continued against Iranian military infrastructure, Iran has launched further missiles and drones across the region, and disruption around the Strait of Hormuz has pushed energy markets into another period of severe uncertainty. The United States now faces a problem larger than the destruction of Iranian military capability: the attempt to destabilise Iran’s leadership has not yet produced political liberalisation, but instead appears to have accelerated the consolidation of power around another figure deeply embedded in the existing security establishment. The broader lesson is uncomfortable: destroying the leadership of an authoritarian system does not necessarily weaken the system’s underlying political logic; external attack can instead make continuity appear safer than reform at precisely the moment when reform might otherwise have become possible.
Mojtaba’s selection exposes a fundamental contradiction inside the Islamic Republic’s theory of legitimacy. Iran formally presents the supreme leader as the product of a religious-constitutional system rather than hereditary succession. The Assembly of Experts selects the leader, and political authority is justified through the doctrine of velayat-e faqih, or guardianship of the Islamic jurist. Yet political institutions acquire legitimacy not only from their formal procedures but from whether citizens believe those procedures genuinely constrain outcomes. If the son of the previous supreme leader inherits the most powerful office after years of speculation that he was being prepared for precisely that role, the distinction between a revolutionary republic and a political dynasty becomes harder to sustain. A constitutional process can remain legally valid while losing sociological legitimacy if citizens increasingly believe the outcome was predetermined by elite power.
However, this does not mean Mojtaba’s succession is necessarily evidence that the regime is about to collapse. In fact, elite continuity during wartime can demonstrate the opposite. Political systems become most vulnerable when nobody knows who possesses authority after a leader disappears. Iran’s institutions have produced a successor rapidly enough to prevent an obvious vacuum. That matters because authoritarian durability depends heavily on elite coordination. Revolutionary Guards commanders, clerics, provincial officials and bureaucrats need to know whose instructions should be followed. A successor who is already connected deeply with those networks may be politically unattractive to protesters while remaining highly effective at preventing fragmentation inside the state.
This distinction between popular legitimacy and organisational capacity is crucial. A government can possess little enthusiasm among citizens while remaining durable because its institutions coordinate better than its opponents. Iran’s opposition remains politically diverse: republicans, monarchists, reformists, ethnic movements and younger secular protesters can agree that the existing system should change without agreeing on what replaces it. The state, by contrast, already possesses ministries, security forces, taxation systems and command structures. Political revolutions therefore are not contests simply between popularity levels. They are contests between organisations. A relatively unpopular but highly organised state can defeat a much more popular but fragmented opposition repeatedly.
Foreign attack can strengthen that organisational advantage because war changes political priorities. Before the February strikes, Iran was experiencing serious protests over inflation, corruption and political repression. Under bombardment, the regime can redefine the central political question from “does this government deserve to rule?” to “can the state survive foreign attack?” Those are not the same question. Citizens who oppose clerical government may still prefer state continuity to national fragmentation or foreign domination. This is why regime-change strategies so often misunderstand nationalism. Political communities can reject their rulers while defending the state those rulers currently control.
The succession therefore complicates the American and Israeli assumption that decapitating Iranian leadership would create conditions for political transformation. Leadership strikes can disrupt command systems and weaken military operations. Their political effects are much less predictable. Killing a dictator can remove a focal point of repression; it can also eliminate the individual capable of negotiating a settlement and empower harder-line successors whose legitimacy depends more heavily on resistance. Decapitation creates political space, but political space is neutral. The best-organised actor usually fills it first.
The Strait of Hormuz makes the consequences global. Iran has continued threatening or restricting maritime movement around a waterway carrying a major share of global oil and liquefied natural gas exports. Energy prices have risen sharply as markets price the probability of prolonged disruption. This demonstrates again that military power cannot be measured simply by comparing defence budgets. The United States possesses overwhelming conventional superiority, but Iran possesses geographic leverage capable of transmitting the cost of war into the global economy. A relatively inexpensive mine, missile or drone near a shipping lane can influence the price of millions of barrels of oil because markets respond to expected risk rather than only physical destruction.
India is particularly vulnerable to this mechanism. Higher oil prices increase India’s import bill, place pressure on the rupee and raise costs across transport, fertiliser, manufacturing and household consumption. The effect can eventually reach monetary policy if energy-driven inflation becomes persistent. India therefore has a direct national interest in de-escalation even though it is not a combatant. This is one reason New Delhi’s longstanding relationships with Iran, Israel, the Gulf and the United States remain strategically useful. Multi-alignment creates diplomatic value precisely when partners begin fighting one another, because a country that has preserved communication across rival blocs retains more options than one whose relationships are ideologically exclusive.
The war also creates a deeper problem for nuclear non-proliferation. Iran’s leadership now possesses even stronger evidence for the argument that conventional military vulnerability invites external coercion. Whether Iran still retains enough nuclear infrastructure to move towards a weapon is uncertain, but the political incentive to obtain an ultimate deterrent may have increased considerably. The lesson observed by other states is potentially damaging: Iraq lacked nuclear weapons and was invaded, Libya abandoned its programme and its regime later collapsed, Iran remained below the weapons threshold and has now experienced repeated direct attacks, while North Korea possesses nuclear weapons and is treated with extreme military caution. These cases are not equivalent, but strategic decision-makers learn from simplified patterns because they need rules for survival under uncertainty.
This is why the eventual settlement matters more than the number of Iranian facilities destroyed. If a post-war Iran accepts intrusive inspections and receives credible sanctions relief and security assurances in return, the international system can still demonstrate that remaining non-nuclear produces benefits. If the lesson instead becomes that negotiations and inspections leave states vulnerable while actual nuclear possession prevents intervention, the war could reduce Iran’s immediate capability while increasing proliferation incentives globally.
The conflict therefore needs a political termination strategy urgently. The United States and Israel can continue destroying Iranian military infrastructure, but each additional strike needs to be connected to a defined objective. Is the purpose preventing nuclear weaponisation, reducing missile capacity, changing Iranian regional policy or overthrowing the Islamic Republic? These goals overlap but are not identical. A campaign designed to achieve all of them simultaneously can become effectively unlimited because no finite number of air strikes can guarantee that a ninety-million-person country will never again possess hostile intentions or dangerous technology.
Mojtaba Khamenei’s succession should sharpen that reality. The Iranian state has absorbed the death of its most powerful leader and produced another. That does not prove the system is stable, and the political contradiction of hereditary-looking succession may become a major source of future opposition. But it demonstrates that the Islamic Republic is an institution, not simply one man. Removing additional individuals therefore cannot substitute indefinitely for deciding what political behaviour would cause military operations to stop.
This is ultimately the difference between punishment and strategy. Punishment imposes costs because an adversary has behaved intolerably. Strategy uses costs to change the adversary’s future incentives towards a defined equilibrium. The first can continue as long as targets remain. The second requires an answer to what acceptable behaviour looks like afterwards.
Iran’s new supreme leader inherits a state under enormous pressure, an economy facing another energy and currency shock, a population that had already demonstrated substantial dissatisfaction and a security establishment whose political importance has probably increased because of the war. That combination could eventually produce reform, harder authoritarianism or another internal crisis. Foreign governments cannot determine which one through bombing alone.
The central question after this week’s succession is therefore not whether Mojtaba Khamenei possesses the charisma or religious authority of his father. It is whether the Iranian political system can continue demanding obedience through revolutionary legitimacy when its leadership increasingly resembles hereditary succession and its survival depends increasingly on military institutions. The Islamic Republic has survived the death of Ali Khamenei. Whether it can survive the contradictions exposed by the way it replaced him may prove a much harder question.
