Have they avoided the worst, or simply delayed the inevitable? Ten days after airing their differences publicly, Vladimir Putin and Recep Tayyip Erdogan agree to a buffer zone deal around Syria's last major rebel stronghold. Has Idlib and its nearly three million citizens been spared? Or will the deal - which includes joint patrols by the Russians and the Turks - unravel?
Syria always seems to be one wrong move away from a turn for the even worse. Take the disappearance of a Russian military transport plane off the coast. We'll see why the downing of that plane concerns not only Damascus and the rebels but also Israel, France and the United States. A reminder that any incident in Syria carries with it a domino effect.
