Karsai is just looking for a way out so he doesn’t get Najibullah’d when the US pulls out.
I guess he is smart seeking support from Turkey rather than neighbor Pakistan. I can remember when Vietnam sought far away Soviet aid and Albania sought far away Chinese aid. New saying, “Hold your friends close, but get big friends from far away places.”
As if that will help. The last US personnel leaving his office should set a pistol and one live round on the desk.
