How could Isis be eliminated? In the region, everyone knows. All it would really take would be to unleash the largely Kurdish forces of the YPG (Democratic Union party) in Syria, and PKK (Kurdistan Workers’ party) guerillas in Iraq and Turkey. These are, currently, the main forces actually fighting Isis on the ground. They have proved extraordinarily militarily effective and oppose every aspect of Isis’s reactionary ideology.
But instead, YPG-controlled territory in Syria finds itself placed under a total embargo by Turkey, and PKK forces are under continual bombardment by the Turkish air force. Not only has Erdoğan done almost everything he can to cripple the forces actually fighting Isis; there is considerable evidence that his government has been at least tacitly aiding Isis itself.
