There is activity on two fronts. We have stated that we are pulling our troops from Syria, to wit, the Middle Euphrates River valley and the Deir Ez-Zor borderland with Iraq. Second, the Turks are threatening Kurdish occupation of the far northeasternmost province of Syria. This salient (it is like a finger sticking out on land west of the Tigris River) is home to a predominant Kurdish population. It is protected by the US whose presence in Iraqi Kurdistan has passed without notice. In this region, Turkish threats not only threaten Kurdish occupation (a fait accompli), but direct conflict with US forces.
Sooner or later Turkey and the US will come to blows. Count on it.
There's at least half a dozen fronts right now in Syria.
Turkey and the US may indeed come to blow.
As in one.
And that will be it for the Turks.
