Iran has killed approximately 900 Americans since 1979. Not many, I know. Hamas killed more Jews, including American citizens, in one day. "Crippling sanctions"? Not enough to force Iran to give up its nuclear weapons research or ballistic missiles. It armed itself to the teeth while not even able to provide water for its own people.What did Iran do to the US besides funding and arming proxies? If you condemn them for doing that then you have to condemn the US for doing the same thing and worse. The US has been waging war against Iran for nearly 50 years with crippling economic sanctions, but not vice versa
Iran is a theocracy with every intention of subjecting the world to Muslim domination. It's part of its religion. The only way to deal with it is to dismantle the regime. They will not go quietly. Anyone who hoped for that knows little of Islamic beliefs, especially the particular brand of Shia practiced by the Iranian regime.
