Iran has a new Supreme Leader. What it does not have is a new Supreme Leader who was selected under conditions that confer the kind of authority the position is supposed to carry. Mojtaba Khamenei was chosen while his country was under active military bombardment, while the Assembly of Experts was voting remotely to avoid being killed, and while Israeli officials were explicitly threatening to assassinate whoever the body selected. This is not a footnote to the succession story. It is the succession story — and it creates an internal legitimacy crisis that will haunt every decision the new Supreme Leader makes.
Wartime Selection Is a Different Animal Than Peacetime Succession
Every previous Supreme Leader of the Islamic Republic was selected under conditions that, whatever their flaws, allowed the process to claim theological legitimacy. Khomeini founded the system and embodied its legitimacy personally. Khamenei was chosen in 1989 in circumstances that were politically engineered — Rafsanjani reportedly manufactured the claim that it was Khomeini’s dying wish — but the process occurred in peacetime, with the clerical establishment physically assembled and able to deliberate.
Neither of those conditions applied to Mojtaba Khamenei’s selection. The Assembly of Experts voted remotely because Iran was under active Israeli and American airstrikes, as Reuters documented in its coverage of the succession race. Time Magazine reported that Iranian officials delayed naming a new leader specifically because of fears the chosen person would be immediately targeted for assassination. Israeli Defense Minister Israel Katz made this threat explicit: whoever leads Iran, he said, would be an unequivocal target for elimination.
The new Supreme Leader therefore begins his tenure under a constraint that no predecessor faced at the moment of selection: an external military power has publicly committed to killing him. This is not a peripheral security concern. It shapes every public appearance he can make, every institutional relationship he can build, and every display of authority that is supposed to communicate to the Iranian population that the Islamic Republic remains a functioning state.
The Dynastic Contradiction Adds a Second Legitimacy Wound
Iran’s political theology has explicit anti-dynastic foundations. The 1979 revolution was, in significant part, a rejection of the Pahlavi monarchy’s hereditary logic. Ali Khamenei argued for decades that one of the revolution’s greatest achievements was ending hereditary rule as a principle of Iranian governance. Mojtaba Khamenei’s selection inverts that principle entirely — it establishes, for the first time in the Islamic Republic’s history, that the Supreme Leadership can be passed from father to son.
The Conversation noted that this represents a potential theocratic version of the very hereditary monarchy the revolution overthrew. Al Jazeera reported that Mojtaba has never held elected office, has never given public speeches, and has never been tested through any public political process. He only received the title of ayatollah in 2022. The Middle East Forum observed that some outlets still refer to him as a lower-ranking hojjat ol-Islam rather than a grand ayatollah — meaning even his clerical credentials are contested.
The legitimacy deficit is therefore double: he lacks peacetime mandate AND he lacks independent clerical standing. Khomeini had mass popular legitimacy from the revolution itself. Khamenei had a manufactured clerical promotion but at least three decades to consolidate authority. Mojtaba enters office with neither the foundational religious standing nor the peacetime conditions that would allow him to build it.
History Shows Why This Matters for Internal Stability
Iran’s political system was designed with the assumption that the Supreme Leader’s authority would derive from a combination of religious standing and institutional position. Remove the religious standing and you have a bureaucrat in clerical robes. The Atlantic’s analysis of the succession crisis raised precisely this question: whether the Islamic Republic’s legitimacy is institutional or personal. If it is personal — if it derives from the specific figure at the top — then a figure who lacks personal authority creates an authority vacuum that the institutional machinery cannot fill.
Historical precedents outside Iran are instructive. Leaders selected under duress, through dynastic rather than merit-based processes, and in conditions that prevented genuine deliberation consistently face heightened internal challenges to their authority. The Trump administration explicitly rejected Mojtaba’s candidacy and called him a lightweight, according to Times of Israel reporting. This kind of external delegitimization — however cynical its source — adds fuel to internal doubts that the new Supreme Leader will need to suppress through coercion rather than persuade away through authority.
What This Actually Means
Mojtaba Khamenei begins his leadership with multiple legitimacy deficits stacked on top of each other: no peacetime mandate, no independent clerical authority, dynastic contradiction with founding principles, external assassination threats, and active military conflict. Each of these would be manageable in isolation. Together, they make legitimacy Iran’s biggest internal threat — more dangerous to regime survival in the medium term than any military strike.
A Supreme Leader who cannot consolidate legitimacy must rely entirely on coercion, which means the IRGC becomes even more central to governance than it already was. The regime becomes more repressive because it has no other tools. More repression increases the probability of popular resistance. More popular resistance during wartime is the scenario the Assembly of Experts feared most — which is why they made the selection they made, under fire, in a remote vote, hoping the speed of the decision would compensate for the weakness of its foundation. It won’t. News.az and CNN reported the selection as a resolution. It is the beginning of a legitimacy problem that may have no resolution.
