This is rarely ever the problem for the military power doing the invading. The problem stems from the vacuum of legitimate governance that occurs when the invader destroys the institutions keeping order. Rogue elements emerge, the like...those we are trying to prevent the government of Iran from giving nuclear weapons in the first place.

I believe the US and its allies have a pretty good overview of where the nuclear installations are. Bombing those alone (not any other military or governmental facilities) would not create any power vacuum, and the institutions that are keeping order would be largely unharmed (unless they build their Congress and presidential residence at the site of nucelar development).
