Bulgarian, Greece, Armenia, Georgia, the Kurds and anyone else threatened by the Turks should forge a mutual defense alliance against any such revival of the Turkish scourge. Alone they are too weak, and they sure can’t count on the US to defend them (rather the contrary). Maybe the Russians can help provide a protective shield, and maybe Trump really will pull out of NATO to give them the latitude they would need to do this.
Forgot, Cyprus would be another natural defense pact member.
