Iran is tearing itself apart in real time after the killing of Supreme Leader Ayatollah Ali Khamenei in joint US–Israeli strikes, with the country’s streets offering dueling visions of the future.

In Tehran’s religious quarters and shrine cities like Qom and Mashhad, black‑clad mourners flood the streets, beating their chests and weeping beneath giant portraits of the fallen leader. State TV loops images of mass prayers and vows of revenge, announcing days of national mourning and promising that “the path of the Imam will not bend.”

But in Karaj, parts of south Tehran and Kurdish and Baluch towns, fireworks, car horns and clandestine dancing have erupted after dark. Videos shared on banned apps show young Iranians tearing down regime posters, chanting “No Shah, No Supreme Leader” and flashing victory signs as sirens wail in the distance.

Security forces are responding with a steel fist: armored vehicles at major squares, internet throttled, plainclothes agents grabbing suspected organizers from crowds. At the same time, hard‑line IRGC commanders are using the funerals to rally support for a wider war, urging “unity behind the missile” as US and IDF jets continue to pound military targets across the country.

Inside fortified compounds, clerics and generals are locked in a vicious succession struggle that will decide whether Iran doubles down on confrontation or risks opening the door to change. On the streets, the split is already visible: some carry Khamenei’s image as a martyr; others carry only their phones, filming — and daring the world not to look away.
