The Syrian Kurd scenario is quite complex. They straddle both sides of the fence and have often been their own worst enemy and a great ally (situationally driven). Their conditions didn't spiral out of control as badly as most western, hysterical media and pundits predicted. We still enjoy a healthy relationship with them on the ground. Strategically, it's likely easier for them to leverage their influence without having us right there. They prefer to leverage our existence in the form of bombs, missiles, and the occasional SOF raid. They like us over the border in Iraq, keeping the Turks in check. They are a savvy bunch.
Kurds in general are complex, spread across 4 countries. Even with their abandonment in 1991, the Iraqi Kurds enjoy the most power and stability in the region, insulated from much of the general drama that is a characteristics of their people.
The complexity of the entire situation exceeds MSM's ability to explain. It certainly exceeds the capacity and capability of your average congressmen and senator.
