NO! Actually, the instability has been in our interest. We "owned" a lot of the problems in the Middle East because of our past actions. The problem of Syria enabled us to get it of our hands, and it sucked all the energy out of the rest of the Middle East. It's a tragedy for the people there, but it's out chance to divest ourselves.
The U.S. has no interest in removing or supporting Assad. Our interest is in letting it now be our problem.
Why you think being Iran's tool and protecting their asset, and indirectly attacking Israel makes no sense to me.
By either supporting or opposing Assad, we are just making it worse for ourselves.
I’m not sure I understand what you said.
Would you take another run at it?
