The chance of Iran having regime replaced dropped to, like, zero.

Besides, Israel wont allow democratic or other functional regime change. Their goal is failed state with forever civil war in it. Something they can regularly bomb whenever it will seem functional. This can still happen, so everyone around should be ready for refugees waves.

Trumps idea of regime change is replacing head for someone who pays him personally - while keeping regime in place. This wont happen now.

Iranian monarchists want own dictatorship, but wont be getting it either.

Iranians who protested were just fucked and that is all about it.
