From the article:
He added, “We have made progress in al-Dolab area, in which ISIS has withdrawn from to the villages beyond, after the battles which involved a private American force , and provided a great impetus firearm, and opened hubs around the region enabled them to storm and surprise ISIS fighters”
What, exactly, is a “private American force”? Blackwater or somebody?
I am much inclined to think a concerted, on the ground, military effort by the U.S. and perhaps a few allies with real capacity like the Brits, Aussies or Canadians, could crush ISIS pretty readily. It would be a mess in cities like Mosul, but there are probably plenty of people in Mosul who would rat them out or even join against ISIS.
The Turks would be very useful, but the price of their cooperation seems to be overthrowing Assad in the process, which the U.S. is not inclined to do.
