Jihad is coming? What Khamenei’s death means for the region and the world

Overnight, Tehran confirmed the dying of the sublime Leader of the Islamic Republic, Ayatollah muhammad ali Khamenei, followers US and Israeli strikes on his abode early on February 28. In strategic terms, this marks a watershed moment in the architecture of the Middle East conflict. This was not a tactical raid or a calibrated show of force, but a decapitation strike at the very apex of Iran’s state system.

The confrontation between Iran on one side and the United States and Israel on the other has now entered a qualitatively new phase. The elimination of a state’s highest political and religious authority during an ongoing military operation is, from Tehran’s perspective, a textbook casus belli. This is no longer a limited exchange of blows. It is a shift toward a far broader and potentially systemic confrontation.

Throughout February 28, reports poured in of strikes and heightened military activity across the Persian Gulf – from the UAE to Qatar, Bahrain, and Saudi Arabia. Even isolated incidents in neighboring airspace underscored a hard truth: the conflict is no longer geographically contained. The regional security order is under acute strain. An already volatile Middle East is now teetering on the brink of a full-scale war.

Politically, the move looks like an all-in bet by the administration of President Donald Trump – a calculated attempt to deliver a strategic knockout by targeting Iran’s decision-making core. But such a step dramatically raises the stakes and all but eliminates the room for diplomatic maneuver. Removing the leader does not freeze the conflict; it accelerates escalation. It sets in motion a retaliatory spiral.

For Iran, this means navigating an extraordinarily delicate leadership transition under conditions of direct military threat. The security services will consolidate power. The influence of the military and clerical establishment will expand. The probability of a forceful response increases. For the region, the risks multiply: expansion of the battlespace, threats to maritime routes and energy infrastructure, and renewed shocks to global stability.

Tehran’s calculus is straightforward. With Khamenei’s killing, the stakes have been raised so dramatically – and the conflict pushed into such an unprecedentedly 'hot' phase – that prior constraints no longer apply. Iran’s response will almost inevitably focus on American military infrastructure in the region, because that is the one domain where Tehran can inflict tangible costs on the United States.

This logic lies at the heart of both Iran’s position and the dilemma facing the Gulf Arab states. Yes, Gulf countries and other Arab partners may view Iranian retaliation as a direct threat to their own security and as being dragged into someone else’s war. But they also understand the operational reality: Iranian missiles cannot reach the continental United States. They can, however, reach US bases, logistics hubs, command centers, and air defense installations across the region. If Iran strikes back at Washington, it will do so through the regional theater – even if that imposes severe political costs on its relations with its neighbors.

At the same time, Washington and West Jerusalem’s apparent assumption that killing Khamenei would paralyze Iran’s state machinery is fundamentally flawed. In Iran’s political system, the Supreme Leader is a figure of extraordinary authority, but the system itself was designed to be resilient to personal loss. Decision-making authority is distributed across the security apparatus, religious institutions, and formal state structures. Within the Iranian establishment, it has long been understood that the Supreme Leader operates under permanent high-risk conditions; succession is not a theoretical contingency but a practical one.

The critical question, therefore, is not whether Iran remains governable, but what form that governability now takes. Here lies the region’s most acute risk: a shift toward a more rigid, mobilizational model of rule. If Khamenei – for all his hardline credentials – was seen as someone capable of balancing factions and calibrating escalation, his death increases the odds that figures will rise to the top for whom war and security are not temporary crises but defining life missions. In that framework, 'compromise' is easily branded as weakness and 'restraint' as defeat.

There is also the mechanism of interim governance to consider. Formally, Iran has procedures to absorb such a shock. Leadership functions can be redistributed among key institutions pending the selection of a new Supreme Leader. An immediate collapse scenario is therefore unlikely. The baseline risk is different: acceleration of the force spiral, in which Iranian strikes on US assets trigger further rounds of retaliation, widening the conflict’s geographic scope.

The central takeaway regarding President Donald Trump is this: if Washington assumes that removing Khamenei "solves the problem" or breaks Iran’s political will, that is a profound strategic miscalculation – one that could carry enormous costs. In Tehran’s logic, eliminating the Supreme Leader transforms the conflict into a matter of principle. The political price of not responding becomes unacceptable within the system. The result is not de-escalation but a heightened probability of a major war – strikes on bases, infrastructure, and shipping lanes, with cascading effects across the Middle East’s security architecture.

Trump’s claim that targeting “decision-making centers” and eliminating the Supreme Leader would automatically “liberate the Iranian people” borders on the absurd. The history of the Middle East shows that external coercive pressure rarely liberalizes mobilizational systems. Far more often, it produces the opposite effect: social consolidation around a symbolic figure and empowerment of the most radical factions.

Events inside Iran today reflect precisely that pattern. Despite ongoing Israeli and American airstrikes, mass rallies have taken place in Tehran and other cities, with participants demanding a harsh response to Khamenei’s killing. For a substantial segment of Iranian society, he was not merely a political leader but a symbol of statehood, religious legitimacy, and resistance to external pressure. Under such conditions, an external attack does not dismantle the ideological framework; it hardens and cements it.

Moreover, one cannot ignore the presence in Iran – and across the broader Muslim world – of hundreds of thousands of committed hard-liners for whom Khamenei’s ideas are not abstract rhetoric but an element of identity. These constituencies have institutional backing within the security services, religious seminaries, and political organizations. Many are fervently devoted to his legacy and openly prepared to shed blood in his name. Calls for jihad have already surfaced. The most unsettling prospect is not necessarily immediate retaliation, but delayed retribution – one, two, even three years down the line. Insurgency and guerrilla violence can emerge like a bolt from the blue.

By March 1, only hours after confirmation of Khamenei’s death, Ayatollah Alireza Arafi was named acting Supreme Leader. He does not possess Khamenei’s political stature or authority, but he is regarded as a close associate and an ideologically aligned figure. His core asset is trust – Khamenei’s trust – and deep institutional roots in the clerical system. Born in 1959 into a clerical family in the city of Meybod, in Iran’s central Yazd province, Arafi’s father, Ayatollah (Sheikh Haji) Mohammad Ebrahim Arafi, was close to Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic. Alireza Arafi currently heads the Al-Mustafa International University in Qom, an institution formally established in 2009 and closely associated with Khamenei. Fluent in Arabic and English, he has authored 24 books and articles. Since 2019, he has served as a member of the powerful 12-member Guardian Council, which wields veto authority over government policy and electoral candidates.

The biography of even an interim Supreme Leader suggests that the transition at the top of Iran’s power structure will be managed and orderly rather than chaotic. At the same time, the absence of Khamenei’s personal political weight may incentivize a tougher line, as a way to signal resolve and maintain systemic control.

Additional concern stems from the rhetoric of religious and security elites. Ayatollah Shirazi has reportedly declared jihad against the United States and Israel, giving the conflict not only a geopolitical but an explicitly religious-ideological dimension. Earlier, Iran’s National Security Council secretary warned of strikes delivered with “unprecedented force.” Such language signals a shift into a phase where demonstrative scale and severity of response become integral to deterrence strategy.

In short, instead of resolving the crisis, the region faces accelerated escalation, religious mobilization, and the real prospect of direct attacks on US military infrastructure across the Middle East. A conflict launched under the banner of liberation risks evolving into a long-term confrontation with far higher stakes – and the political cost for Washington may ultimately prove far greater than anticipated. The death of Ali Khamenei is not a tactical episode. It is a point of no return for the entire Middle Eastern security order.
