February 28, US and Israeli forces struck Iran. The War Powers clock started at midnight. Day 60 is April 29. If Trump doesn't obtain Congressional authorization by then, he must begin withdrawing forces from the operational theater.
Standard analysis: this constrains Trump. He needs Congressional votes he may not have. The antiwar faction of his own party is small but real. The authorization vote is uncertain. Therefore the military operation has a structural time limit.
Correct. But here is what follows from it that the standard analysis misses: the War Powers deadline also constrains Mojtaba Khamenei — and more acutely.
When the US military operation ends, it ends one of two ways:
Version A: Mojtaba installs. He opens a back-channel — Oman, Qatar, some intermediary. The US and Iran reach a mutual understanding: Iran reopens Hormuz, pulls back Hezbollah support, US suspends active strikes, talks begin on nuclear architecture and sanctions. The US military posture changes because Iran and the US reached an arrangement. Mojtaba can claim he managed the crisis. His first act in office was to stop the war on terms he negotiated.
Version B: Congress acts. The authorization vote fails, or the clock runs out without a vote. US forces begin drawing down. Iran gets the withdrawal it wanted. But the withdrawal happens because American domestic politics required it — not because Mojtaba did anything. The new Supreme Leader watches his primary adversary leave for reasons that have nothing to do with him.
Version B is catastrophic for Mojtaba's founding story. He "won" because an American law said Trump had to stop. That's not a story. That's a footnote.
Every supreme leader needs a founding narrative. Khomeini had the revolution. Khamenei had the war with Iraq — he survived Saddam's invasion and positioned himself as the guardian of the Islamic Republic's integrity through eight years of conflict. The story is: this is the man who held it together when it mattered.
Mojtaba is inheriting a hot war. The IRGC generals who elected him want a leader who can be strong. The Iranian public — under sanctions, with exports at 10% of normal capacity, watching $200 million per day flow out through the closed strait — wants someone who can navigate this without collapse. These are not contradictory demands, but they require careful management.
The founding story Mojtaba needs is: I stabilized the regime under maximum pressure, and I got terms that preserved Iranian dignity. That story requires a negotiated outcome. It requires him to have been the agent of de-escalation, not a passive recipient of American domestic politics.
If Version B happens, his story is broken before it begins.
The Congressional authorization debate doesn't heat up on Day 60. It heats up around Day 30 to Day 45 — when the vote becomes imminent, when whip counts start circulating, when the administration has to publicly lobby. That window is approximately late March through mid-April.
Before that debate locks in, there is a diplomatic track available. The US administration almost certainly prefers Version A to Version B — a negotiated outcome that lets them claim strategic success rather than a Congressional retreat. If Mojtaba installs and signals willingness to talk through back channels, the administration has every reason to engage. Both sides want the deal track, not the clock track.
After the authorization debate is fully engaged — after the vote starts to look close or failed — the diplomatic track gets crowded out. The story becomes about domestic politics. Congressional opponents own the narrative. The administration is playing defense. Mojtaba can't open negotiations in that environment without looking like he's doing it because he has to.
His window: install before Day 30 (March 30), begin signaling before Day 45 (April 14). After that, Congress consumes the oxygen regardless.
This is why the current delay — Day 5 as of this writing, March 5 — is expected to be brief. The regime is not deliberating about whether to install Mojtaba. That was decided March 3, confirmed through the Assembly of Experts vote. The delay is about managing the announcement: timing it with burial rites, ensuring internal messaging is coordinated, avoiding the appearance that Khamenei's replacement was rushed.
These are legitimate institutional concerns. They don't require weeks. They require days. Mojtaba himself has every incentive to push for a fast announcement — because every day of delay is a day of leverage lost.
My 80% probability that Iran formally names a new Supreme Leader by March 10 is not based primarily on Polymarket pressure or historical succession speed. It's based on this: Mojtaba's interest in installing quickly is more urgent than any other factor pushing for delay. Day 5 of delay is normal. Day 15 would mean something changed in the internal dynamics we can't see.
If this logic is correct: Mojtaba installs before March 30 (Day 31). The back-channel signal — through Oman or Qatar, a "willingness to discuss" phrasing in some official statement — comes within two weeks of installation. And when the War Powers clock debate begins in earnest, the diplomatic track is already open.
If Mojtaba is still not installed by March 25 (Day 26), update toward: internal Iranian dynamics are more constrained than the strategic logic suggests. The IRGC hardliners may be extracting concessions from Mojtaba about policy commitments before allowing the announcement. The delay would then reflect negotiating leverage flowing the other direction — inside Iran, not toward the US.
And if Mojtaba installs but makes no diplomatic move before April 14 (Day 45): the autopilot model remains correct. The cold switch is available but hasn't been used. Either the inaugural risk model holds (he can't de-escalate without something from the other side first), or the IRGC is the constraint, or the hot default has more institutional momentum than any new leader can interrupt quickly.
