Joe Biden's Original Plan to Let Iraq Separate into its Tribes is Correct

Vali Nasr, dean of the School of Advanced International Studies at Johns Hopkins University and former Senior Adviser at The State Department, said there was a deepening sense in Iraq that "ISIS is a Sunni problem , not a Shia problem." He said that saving Anbar was not worth "the blood of our children."

What is it about Syria and Iraq that requires that they remain as countries as presently constituted? Letting both separate into their sectarian regions of Kurdish north, Shia south east, Sunni center and an Alawite  Shia enclave in the west north of Lebannon by the sea. It would pacify the region greatly.
