The killing of Soulemani is a show of force, a deterrent. It is nothing more than that. The head of the snake was killed. If the Iranians want peace, they should not support terrorists.
Iran has been killing Americans indirectly for many years. That is what they do. No amount of appeasement will change that. I don't believe they want war and don't think we will start a war. The Iranians are big talkers. They can't possible match the US in military might.
* The only thing they can do is terrorist actions via proxies. *
If they do anything like Saddam did, it will be the end of that regime.
Iraq did not tell us to GTFO. There was a non-binding resolution.
The only nation with a say in the ME is the US. We are the only ones with troops there. What nonsense are you talking about?
