Exactly, or something happens in the meantime.
There are scenarios where a POTUS can act unilaterally and legally. At least for now, President Obama has acted cautiously, yet forcefully. He is using every means short of raining annihilation from the sky on Syria and risking a large scale war for no real good reason.
I'm pretty sure he has a bit more insight into things that you or that weasel thing have. So far he has been rational. That's about all I can hope for these days.
Did you support the poorly chosen war in Iraq, and the poorly planned war in Afghanistan when they were started?
Yes, you did.
