Iranians are not rebelling against the IRGC because why would they? Generally an outside attack makes the government more popular, not less.
They still don't love the regime but today they share a common enemy.
Two full decades in Afghanistan "liberating" the Afghani people from the Taliban, when you left it took less than a day to undo with zero resistance, that's how much the population appreciated your efforts to "bring them liberal democracy".
I suppose it's because the US public never had to reconcile their fantasies with reality in quite the same way as them.
Obviously it's not up to me to decide for them. It's not like we gave Aghanis the option to move out if they didn't like it. Still...
I wonder what you think that means and why they rejected it?
