I just listened to the Erik Prince interview 11-4-16 and Houston we got a Problem.
ISTANBUL, Turkey (Kurdistan24) – Turkey’s President Recep Tayyip Erdogan invoked on Monday an early 20th-century irredentist document that claimed the Iraqi city of Mosul as Turkish soil.
Includes Northern Syria and parts of Greece. This explains why Erdogan told Assad he doesn't recognize his Northern Border.
This is what Erdogan is up to, default the Treaty.
