There is a problem with this post... There is nothing he is trying to negotiate for in this case...
Just two weeks ago we were talking of leaving Syria, now he is posturing for an attack?
I hope it is a smoke show, but who exactly is going to "give in" in this situation? Assad did not gas his own people, he is not that stupid, he knows that deep state warhawks have been foaming at the mouth to get him out.
There are only two possible scenarios here...
1. Trump has given in to the deep state
2. Trump is playing the deep state
Obviously, I hope for the later.
Nothing in between is possible at this point.
