Iranians are not rebelling against the IRGC because why would they? Generally an outside attack makes the government more popular, not less.

They're not popular, but going outside in a flurry of missiles isn't good for your health. It's not like the US has coordinated with anyone on the ground to plan a revolt. They seem to have just imagined one will materialize.

They still don't love the regime but today they share a common enemy.
