Why this much love for the Marxist PKK? Let ISIS (Turkey) take care of commies (PKK), and vice versa.
I know, right.
PKK is harder to dismiss as just a group of Marxists/terrorists ....it’s become more complicated - they helped the Yazidis who fled to Mount Sinjar in Iraq to escape ISIS and have been fighting against ISIS in Syria.
An imperfect analogy. ISIS are the Nazis. The PKK are the Soviets. You could say let them destroy each other, but there is a real risk that the stronger one will crush the weaker one. Bad news if the stronger one is the worser one.
In 1941 the Nazis were stronger than the Soviets. Today ISIS is stronger than the PKK.
