Bombing the crap out of their country doesn't help normal Irianians though. It only helps Isreal. The Isrealies want a broken Iran in chaos, and the nasty Islamic Theocracy would prefer a bit of destruction to being overthrown by organized internal resistance.
The Iranian regime was on it's way out. A government can't survive killing that many of its own people. But as has been shown many times, the average person will choose opressive order over chaos.
The Iranian people were dangerously close to taking their country back, Isreal made sure that won't happen.
