The power struggle in Raqqa among Sunni rebels will mutate into another ISIS

Inside Raqqa With Fighters Who Faced ISIS shows the defeat of the Sunni Arab Caliphate by a coalition of Syrian Kurdish pesh merga and Sunni rebels to the Bashar al Assad Shiite regime. It's a conquest that has no hand off toward a moderate politic.  The Kurdish retrieval of the Kurdish city of Kobani East of Raqqa from the Caliphate was sustainable because of the Kurd's moderate politic, but Raqqa is not Kurdish nor are they welcome to govern the city.  The political power struggle among the various Sunni rebels to govern Raqqa is sure to mutate into another terrorist group.
