Sure they have. We ran these turds out years ago back when they were calling themselves `al Quaeda in Iraq.’
See, I disagree. I think we (US and tribal allies in Anbar province) killed the hell out of the former AQII. These ISIS guys are all imported from the ISIS stronghold in northern Syria which adjoins both Turkey and Iraq. It includes a large amount of international jihadists from all over the world who fly to Turkey and cross the border into Syria.
The first time an American is killed by one of these ISIS guys, Turkey must suffer.
