Iran isn't being attacked because it's not nice to its own people (which is a shame really, all dictators and theocrats should worry for their lives). It's being attacked because it has ballistic missiles, a nuclear weapons program, a giant sign in the middle of Tehran counting down the existence of Israel and its leaders have repeatedly called for Israel's destruction. So weapon, opportunity and motive. It's of course free to work towards the destruction of Israel but then it's hardly fair to complain that Israel may try to preempt that.

Switch "Israel" with "Iran" and you have basically the same thing, but seemingly waging war against Israel would never be an option, would it? Because we accept the country's own sovereignty, as we should do with all countries.
