One of the more under-reported aspects of the ISIS crisis has been the role of Turkey in facilitating the psychos' success. Not only is Turkey allowing black market sale of oil - a huge benefit to the terrorists, but the group actively recruits in Turkish cities without apparent fear of arrest.
Turkey is a member of NATO. Lying half in Europe and half in Asia, it has striven for acceptance by the West since the breakup of the Ottoman Empire. But over the past decade its responses to backward-looking radical movements in the Middle East have greatly complicated not only its position vis a vis the West but also perceptions of it.
Turkey's way is not necessarily Europe's or even America's; it has its own future to determine. But sleeping with rabid dogs is never a good idea; they tend eventually to bite.
