It’s possible. My first thought was that it was the Russians. I’m more inclined to think it was Benghazi thugs freeing some of their own. Either way, it’s been completely botched by the Democrats.
Probably free lancers or advisor Russians. Could have been some hard core Iranian military. Definitely hard core Syrian military. And of course, some local Al Qeada paid some cash. They can attack US forces anywhere in the world now with that MO and get off scot-free. That is what happens when you make a deal with the devil. And DC has made that deal.
