We are betraying the Kurds for Erdogan and will almost certainly come to regret this.
Unlikely while I despise Erdogan and think the Kurds are the best faction in the entire region (including Israel). The Kurds are used to be betrayed, and doesn't have a tradition of terror outside the region. Also USA seem (to for once) smart enough that they keep supporting the Kurds, they just limit the Kurdish influence, until they have a excuse to nsupport YPG again. Also the Germans seem to have decided to simply throw their vallet after the Kurds.
That's probably because Erdogan hasn't done much to endear Germany.
