Turkey wants a buffer zone with the Kurds to keep the Kurds from attacking Turkish border towns. This is not new. It has been ongoing for hundreds of years. The Kurds are squatters here and there hoping to get a new "Kurdistan" somewhere. Saddam gassed them, killing thousands. If the "final solution" means that some Kurds relocate out of the buffer zone, and that creates peace, no big deal.
You seem to be implying that the Erdogan "final solution" is the extermination of the Kurds ala Hitler's "final solution", and its not. So stop with the dramatics already. Trump got out with no US lives lost, and a "solution" to the Kurd-Turk problem. A win-win-win.
