The tide has shifted, and American public opinion agree it's better to keep Assad and go after ISIS only.
I just don't trust him that he won't still covertly continue with trying to get rid of Assad, think he's been fooling Americans lately, so many opposing forces in Syria, hard to tell which is which.
And how will Americans know for certain what we are really going to do there? We don't. Maybe even the troops don't or will know and can't tell.
Brilliant.
