ISIS's drive to Empire is a Weakness

"Slaughter is Feared as ISIS Nears Turkish Border"  is a depressing headline in today's paper but ISIS is biting off more than it can chew when it conquers a people who do not have even a remote affinity for their vision. They will need police power and counter insurgency defenses if they were to over run the Syrian Kurdish town of Kaboni.  They don't have the manpower.  Thanks to ISIS the Kurdish refugees in Turkey just to the north will form the political means to reconquer, police and govern the area despite Turkey's resistance to Kurdish independence.
