Turkey has gone so far as to outlaw Kurdish language. They recently leveled most of a Kurdish city that had become restive. Turkey correctly views Kurds as a threat to their power in the hinterlands of Anatolia. In fact all of the states with large Kurdish populations - Iraq, Syria, Turkey & Iran - have fought against them, and all (but perhaps Iran) actually got paid by the US to do it. Turkey was the largest recipient of US aid under Clinton when they were taking their shot at them.
