US are pushing hard to make Turks join their so called coalition against ISIS. It's too bad for them that time is changing and old Turkiye which was a forward hq against USSR is no more. One of the main reasons of Turks not joining the alliance was 49 Turkish hostages in hands of Isis. Since they are freed, US will try it again.
Now there are talks about it was cia made isis freed the hostages to convince Turks to jump in.

They are using it to harm just cause of Palestinians, Egyptians, Syrians, Iraqi and other Muslims who are vicitimized by puppet leaders of theirs. They have created a boogeyman to stop advance of Muslims in their colonies.
