Another quid pro quo.
The US pullout of troops in north Syria was the quid. The Quo is what is going on now in Syria. MASS MASSACRES.
Here's the thing. What does the US get out of it exactly? Besides exceeding BAD PRESS? I think it's got everthing to do with the trump tower in ISTANBUL Turkey. Ya gotta hand it to him. He is always on the lookout for ways to enhance his net worth. Never sleeps. Never hesitates. Give him an inch and a mile later he's wanting more. Inexhaustible energy. Source? I have no idea.
