why superpower countries do not overthrow Islamic government of Iran?

[brewer]

If a majority of Iranians don't like the government why don't they revolt?

An outside superpower might be the easy way, but it never lasts.

People have not enough power for regime change.

Also many terrorists are in cities that easily beat and torment people even they kill women easy.

Yeah, that's what the US thought about Vietnam, what the Brits thought about the colonies.

If Iranians are not willing to take a stand, on their own, then you've got problems. Once you/they do I think there would be aid sent from the 'superpowers' that don't like/approve of the state of Iran as it currently stands. The first moves need to come from within Iran.
