Erdogan wants Syria and Obama wants him to have it. Its that simple. Obama is one spoiled brat who will do anything at all to get whatever he wants. I’m being polite and restrained here.
We talk as if Obama were the source of the desires and will behind this, but that probably isn’t the case. He’s probably just a puppet doing what he has been told to do as a good little figurehead, and not giving a care as long as his own hide gets sufficiently celebrated and guarded.
