Earlier quoted context omitted.
"Sure, it can always be worse" Yes, I would argue the islamic state was indeed worse. And so far I see nothing preventing them or a similar force taking hold again. I mean turkey is the moderating factor here and turkey under Erdogan has gone the authorian islamic way since a while.
Drawing analogies between Erdogan and the IS is wild.
Erdogan is as much pro-ISIS as one can be. Maybe just a political game during complex conflict to fight against US-supported kurds at all costs, maybe not. We don't know.
