Turkey's actions now are giving me a wicked sense of 2003-style deja vù (sure, you can use a base here.... on second thought, no you can't). The Turks are willing to allow ISIS to destroy the Kurds all the way up to the Turkish border, and even lend a hand, as we are seeing now.
What I'm not sure about it how confident Erdogan is about ISIS stopping at the Turkish border. Does he think they'll stop with Iraq and Syria? Does he have a plan to cooperate with them if they should come into Turkey? What is his ability to hold on to his position if ISIS has a different idea regarding who's going to be in charge of Turkey? I don't know enough to make those speculations, but I'm damned sure interested in seeing how this is going to play out.
I wish I could be optimistic about the Kurd's chances, but I can't afford that much dope.
