The World Post quotes Rafik Hariri Center Nonresident Senior Fellow Aaron Stein on US-Turkish cooperation in Syria given the increasingly supportive stance of the United States toward Syrian Kurds:
The U.S. appears to be managing Turkey’s concerns by tacitly agreeing that Syrian Kurdish forces will not be allowed to pass into areas west of the Euphrates river, according to Aaron Stein, a Turkey expert at the Atlantic Council.
…
“In any case, Turkey is certainly indirectly aiding the YPG’s advance east of the Euphrates,” Stein told The WorldPost, using the acronym for the Syrian Kurds’ fighting force. “American drones provide intelligence, surveillance and reconnaissance for these missions, and tankers based at Incirlik most certainly refuel U.S. bombers flying from Qatar.”
