ISIS is Turkey.
Yes but why are they seemingly calling on our help to eliminate ISIS?
No matter who gets the upper hand, they’ll be against the USA, of that there can be no doubt.
Are we really this stupid?
I disagree. They may have backed ISIS originally, but when ISIS declared a caliphate, ISIS effectively declared war on every other Muslim government. They no doubt are happy to see ISIS killing Kurds and Shiites, but Erdogan isn't about to kowtow to them. So he has his own Jihadis he is backing to take over Syria.
