What is the future of Iran after the assassination of Khamenei?
The killing of Supreme Leader Khamenei leaves a power vacuum no airstrike can fill
Weeks of military buildup culminated in what no analyst had dared predict as recently as a year ago: a joint US-Israeli strike killing Ayatollah Ali Khamenei, the man who had not merely led the Islamic Republic for three and a half decades but had, in many ways, been it. In the hours that followed, Tehran's skies lit up with retaliatory drones and ballistic missiles. The Middle East, already a region of compounding crises, lurched into genuinely uncharted territory.
At the storm's eye are Iran's 90 million people — many of whom took to the streets last December only to be met with mass arrests and brute force crackdown. For weeks before the strike, the Trump administration had been broadcasting a message to them: help is coming. Now that the help has arrived, in the form of explosions rather than solidarity, the future facing ordinary Iranians looks more dangerous and more opaque than ever.
A Liberation Narrative With No Liberators
Speaking to the Iranian public on Saturday, President Trump struck a triumphal tone: "Your time of liberation has come. When our job is done, take your government back — it's yours. This may be your only chance in several generations." Prime Minister Netanyahu echoed the call, urging Iranians to "pour into the streets in great numbers and finish the job."
But the opposition figures and Iranian civil society analysts watching from the diaspora heard something hollow in those appeals. Military decapitation, even successful military decapitation, does not produce democracy. It produces a vacuum — and vacuums are rarely filled by the people Western leaders imagine filling them.
The most immediate problem is structural. Since the final wave of US strikes in June, real decision-making authority in Iran has migrated away from the Supreme Leader's office and toward two institutional pillars: the Supreme National Security Council and the Islamic Revolutionary Guard Corps (IRGC). The clerical face of the revolution may be gone. Its armed skeleton remains entirely intact.
"What we're likely left with," says historian Arash Azizi, author of What Iranians Want, "is a weakened, wounded, and deeply vengeful regime — one that, if pushed by Trump's provocations, could become even more brutal toward its own people simply to survive."
No Leader Waiting in the Wings
The protest movement that shook Iran last winter was real, widespread, and brave. It was also — like so many of Iran's protest cycles before it — ultimately suppressed. More critically, it produced no recognized leadership, no organizational infrastructure capable of channeling the anger of millions into a coherent political alternative.
Some demonstrators have invoked Reza Pahlavi, son of the Shah deposed in 1979's revolution, as a symbolic figurehead. Others — including Iran's Kurdish nationalist factions, who broadly support the strikes — want nothing to do with a monarchist restoration. The Kurdistan Freedom Party's Hana Yazdanpana put it plainly: "The strikes are welcome, yes. But the people have lost hope so many times before, when promises of outside support came to nothing. We need to rebuild that hope now."
That tension — between celebrating the fall of a hated regime and fearing what comes next — is not unique to Iranians. It is the perennial tragedy of externally-forced political change.
The Chaos Scenario
Azizi's most alarming concern isn't a vengeful IRGC or a power struggle among competing hardliners, though both are real risks. It is that Iran fractures entirely. "There is a genuine danger of severe internal chaos — even civil war," he says. "That would be an absolute nightmare."
Such an outcome might, from certain vantage points, be considered a success. Israel has a long-documented preference for fragmented, internally-consumed neighbors over strong, coherent ones — a dynamic visible from its management of Palestinian politics to its recent maneuvering in post-Assad Syria, where it has deliberately stoked tensions in the country's south to keep Damascus off-balance. A chaotic, permanently destabilized Iran poses less of a conventional threat than a reconstituted one — even a reconstituted Iran friendly to the West.
What Comes Next
The real question is what the Security Council and IRGC leadership do in the immediate days ahead. Khamenei's virulent anti-Americanism and anti-Zionism were partly ideological conviction, partly the legitimizing glue of the entire system. With him gone, figures like Ali Larijani — a former IRGC officer now heading the Security Council — face a choice between doubling down on confrontation and quietly exploring a deal.
"Will the Americans be satisfied with a negotiated settlement with the security establishment?" Azizi asks. "Or do they genuinely believe their own rhetoric — that Iranians will now rise up, or that power will somehow transfer to an exile figure like Pahlavi?"
The honest answer is that no one knows, perhaps not even the decision-makers in Washington and Tel Aviv. What is clear is that the hardest work — building something durable from the wreckage — cannot be done from the air, and cannot be done by outsiders.
Iran's moment of maximum danger and maximum possibility has arrived simultaneously. Whether it becomes liberation or catastrophe depends almost entirely on what Iranians themselves are able to organize, and how much genuine space the external powers are willing to give them to do it — rather than simply declaring victory and watching the rubble settle.
