Actually, it looks to me like Turkey is fighting a one-and-a-half front war. Ankara might claim that it is fighting both ISIS and Kurdish "terrorist groups" but it seems like it is bombing the Kurds a whole lot more than ISIS. More and more, this looks like the Turkish anti-ISIS offensive is little more than a fig leaf to cover its real fight against the Kurds.
By attacking the Kurds, Turkey is helping ISIS. So even with the occasional Turkish strikes against ISIS, and Turkey's new willingness to let U.S. bombers use Turkish bases to attack the group, I'm still not sure if Turkey's actions are not a net gain for the Islamic State. Turkey is hurting one of the few groups on that ground in Syria and Iraq that has proven most effective at fighting ISIS.
