I am aware of Kurd vs Tukey situation and Kurd's feeling of being abandoned after the gulf war. But Kurd have to be in the equation, I think. So U.S. will push all buttons to enlist Kurds. Turkey was bought last fall by U.S. There was a state visit by Turkish President which brought hundreds of businessmen as entourage. Apparently they all got their wish. I know this is not an easy problem. But it has to be worked out. Politically, it is always much better to have inside help rather than outright invasion.
