While there are many evidences that Turkish Gov. helped ISIS, i am having hard times to believe that they actually fights against ISIS.
1. There is enough evidence to prove that the Turkish government agencies actively helped the ISIS during the bomb attack in Suruç, which killed dozens of ethnic Kurds.
2. Turkey has been actively helping the ISIS recruit to cross over to Syria through its territory.
3. Most of the suicide attackers, who targeted the Kurdish positions in the ISIS attack on Kobanî (25th June 2015) came from the Turkish side of the border.
