Phase 2 of this war once most of the launchers are buried will likely involve funding various groups. Azeris in the north, Kurds in the northwest. Whatever is left of IRGC will basically constantly get bombed from the sky while you have these other groups keeping them busy internally and on their borders. By then, Iran's ability to project outward is going to be so severely degraded. In all of this it's likely many civilians will die as collateral damage and/or starve as food, water deliveries break.
IRGC would love for a real detente that's lasting to be announced, but they're not dumb. They know if there is a deal it will be broken again and their leadership will continuously and endlessly be taken out. This is absolutely an existential threat for them.
with a population double that of Iraq, where 1 million died in the 2nd war, i'd expect at least a million die in Iran too. especially if all we do is bomb for the first phase and continue bombing for the second phase too.
all that talk about the pre-revolution Iran which was almost western and a progressive state for Islam. gone. its gonna be a rubble heap of future terrorists.
