I'm not understanding here.

First, Iran needs to be eliminated. It's a Chinese ally and a piece of shit regime that is holding the world hostage.

Second, why is he constantly hawkish and then backing off? I'm really hoping we can get a better understanding of this situation.

The problem isn't ME. It's that this war is HUGELY unpopular and affecting his support. If this continues, we are going to lose the mid-terms.
