Iran’s newly appointed supreme leader, Mujtaba Khamenei, issued his first public statement on March 12, promising unrelenting revenge for the killing of his predecessor and reiterating Tehran’s readiness to use a blockade of the Strait of Hormuz as a lever of pressure. He framed the statement around national unity and the need to punish those responsible for attacks on Iranians, including what he described as assaults on schools that ‘‘will be specially held to account.’'
Mujtaba praised the contributions of the late Ali Khamenei and cast his succession as a heavy responsibility in a moment of crisis. The statement emphasised the centrality of popular solidarity and the armed forces to ensure regime stability, while signalling that Iran will continue to strike military bases in the region that are used to attack Iranian interests.
Beyond reprisals against specific facilities, the new leader explicitly revived the threat to seal off the Strait of Hormuz — the narrow waterway through which a significant proportion of the world’s crude oil transits — and said Tehran is exploring new fronts “where the enemy is less experienced and more vulnerable.” He also vowed vengeance ‘‘for every Iranian who has been killed,’' language that broadens the scope of potential retaliation.
Mujtaba’s statement contained an appeal to neighbouring states to clarify their stances and to close US military bases on their soil, calling Washington’s claim to provide ‘‘security and peace’’ a lie. At the same time, he asserted that Iran does not seek regional hegemony and professed readiness to build ‘‘sincere’’ relations with neighbours, while promising free medical care and compensation for the wounded and damaged property.
The statement also set out punitive measures against adversaries: Tehran says it will demand compensation from those it deems responsible and, if payment is refused, will seize assets — or, failing that, destroy property of equivalent value. That assertion of extraterritorial economic remedy and violent reprisal raises legal and diplomatic stakes beyond the immediate military threats.
Why this matters: the Strait of Hormuz is a strategic chokepoint; any credible attempt to interdict shipping would immediately ripple through global energy markets and force a military response from navies that patrol the gulf. The call for neighbours to expel US forces places Gulf monarchies and other regional partners in an uncomfortable position, intensifying the diplomatic squeeze on states that have been attempting to balance between Washington and Tehran.
Operationally, Iran’s rhetoric combines asymmetric maritime tactics with regional strike capabilities and proxy leverage — a playbook Tehran has used before to signal resolve while complicating a direct, conventional response. The immediate risk is an uptick in harassment of shipping, targeted strikes on facilities perceived as hostile to Iran, and the potential for miscalculation that draws in US and allied forces, with attendant economic and security consequences for a wider international audience.
