# A US-Israeli war on Iran begins; Ali Khamenei is killed

Date: 2026

## The fact

On 28 February 2026 a US-Israeli war on Iran began; Supreme Leader [Ali Khamenei](/people/ali-khamenei) was killed in an airstrike. Iranian state media confirmed the death on 1 March. He did not write the US-Israeli opening order. He was CinC of the confrontation that ended that way.

## Context

January 2026 protests sat weeks earlier. Neighbouring 2025 US nuclear-site strikes are earlier. Mojtaba’s succession is 8 March. Do not convert victimhood into authorship of the munition.

2025 US nuclear-site strikes are neighbouring. January 2026 protests are neighbouring. Pezeshkian’s interim council is 1–8 March.

The Supreme Leader of Iran is commander-in-chief and the highest constitutional authority. He does not write a US presidential strike order, an IAEA Board resolution, or a Hamas military plan. Presidents, the IRGC, and the Guardian Council implement and share specific files.

## Evidence and sources

Office of the Supreme Leader of Iran carries the official instrument or communique. Reuters records the same dated act independently.

## Significance

Authorship of the opening munitions is US-Israeli.

## What is established and what is not

Established: 28 February 2026 war start and Khamenei’s death, independently reported and then confirmed by Iranian state media.

Not established: that he ordered the US-Israeli attack, or a unique personal body-count of the war as his tally.

What would change the picture: a contradictory original with a different date or name, a later repeal, a court that vacated the instrument, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

The US and Israel opened the war. He was killed in the opening strike. He did not write that strike order.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies A US-Israeli war on Iran begins; Ali Khamenei is killed, not a later speech about A US-Israeli war on Iran begins; Ali Khamenei is killed.

Co-authors and later implementers named in Context remain on the file. A US-Israeli war on Iran begins; Ali Khamenei is killed on 2026-02-28 is not a licence to treat every later Office of the Supreme Leader of Iran communique as this same act. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. This dossier refuses to average A US-Israeli war on Iran begins; Ali Khamenei is killed into a personality. The contribution described on this Person row is limited to He was CinC of the Iranian side. The US and Israel opened the war. He was killed in the opening strike. He did not write that strike order. That limit is the alternative to treating office-holding as authorship of every later series.
