Iran sent missiles to countries hosting US military assets. I think that it's quite clear why they do it, unlike the US. They had also warned before hand that it would happen in the case of a US unprovoked aggression.

I'm glad warning before hand is all you need to do. Sounds like you full support the US then. Welcome aboard!

Iran didn't start the war. The countries bring struck are US allies that provide the infrastructure for the strikes against Iran.

"provide the infrastructure for the strikes" -- Put your hate for the Jews aside for a few minutes to realize how hypocritical that statement is
