Israel would have been obliterated decades ago if the US hadn't supported them, and Iran wouldn't be ruled by crazy religious nutjobs today if the US hadn't instigated the 1953 coup.
So the kindest thing you can say is that the US isn't helping in the middle-east.
The more realistic thing you can say about the middle-east is that most of the shit going on there is a direct result of the US not minding their fucking business on the other side of the planet.
