I remember a political cartoon from the '80s that had a boardgame-style spinner with "Send Troops to" written across the top and in the pie wedges, "Grenada" "Beirut" "El Salvador" and a few other countries. It was captioned "Reagan's Policy Distraction Device" or something like that.
Putin is in Syria because ISIS is a great distraction for the west, and because he can look tough without having to do much, and because he's got a policy spinner of his own to deal with his domestic economy issues. I'm skeptical that the Russians have any long-term intentions in Syria; other than getting the West bogged down in the Middle East and a short-term distraction from domestic affairs, there's little upside to their presence.
I guess Lindsay Graham is ready to march. Not personally, of course. Other people's kids, as per usual.
