Russian President Vladimir Putin announced during a meeting with Turkish President Recep Tayyip Erdogan the creation of a "buffer zone" in Syria's Idlib province. It will be a demilitarized area in between Syrian government forces and rebel forces during the looming battle for the territory.
The key challenge for Turkey is not the form of its relationship with the EU, but the fact that it crucially needs EU markets, funds, and investment to prosper. This in turn requires the rule of law, not the rule of the arbitrary. Choices will have to be made in Ankara.
