As far as the Kurdish fighters in NE-Syria defending against the Turk-Syrian National Army forces (T-SNA), it will become a question of Syrian stability. The current Syrian Undertaker government will attempt to rein in the T-SNA forces, but not an easy chore. The T-SNA has had conflicts and battles against the Undertaker jihadis, in the past in NW-Syria. Syrian independence and Turkish expansionism are still in conflict.
