I doubt there will be a ground invasion this time. The current US administration cannot build a coalition (and logistics without a coalition is hard), not will the US public go for it.

And is there really much you can do from the air that wasn't done already?

Either the Iranians do it themselves or it doesn't happen. Sadly, I don't see any good outcomes for the protestors. But you never know, oppressive regimes appear stable, until they are not.
