I do not know whether you are in the mood to answer a question that is particularly dumb. But if you could, I'd appreciate it.
Why wouldn't Turkey give up the arid land in the East and let the Kurds unite with the Northern Iraqi ones?
This does not seem to be a particularly important piece of real estate, and it is so costly for the Turks to maintain. The Kurds managed to maintain identity through centuries, and are unlikely to be ever loyal, in contrast to other minorities in Turkey. Why not let go?
