Well bro, as i said before, Turkey will obviously rather have ISIS in control of north Syria than the Kurds, as it perceive the Kurds to be a far bigger threat to it than ISIS. As I said before, I don't blame them at all since they are not alone, each and every power in this conflict is only looking after their own selfish interests first and foremost (which is normal) be it Iran, Turkey, U. S, Russia, Europe, KSA and it's gulf subordinates etc. it's a huge mess the Syrian people got themselves into thinking they were starting a revolution (some of them even still believe in this after their country has been totally destroyed, filled with terror groups from all over the world, and reduced to a fail state. Lool) .
Hope this will serve as a lesson /case study for other desolutional clueless people in the developing world about learning how geo politics works before attempting any so called 'democratic revolution ' a la Libya.
