policy in syria because terrorism has been exploited to them as well as a huge influx of refugees. do you agree? how could we have prevented this? >> proving that even a stop clock is twice a day. i think assad understands that the president's confusion, his inability or unwillingness to act against assad over time coupled with his unwillingness to do anything effective about isis is what is creating this vacuum, this lack of outside influence that russia is now attempting to exploit. and not just in the syria/iraq context but i think more broadly across the middle east. so it's no wonder that assad and the russians are feeling up it these days because they've taken advantage of this vacuum and they are filling it. >> and finally, what should we do? no fly zones? hillary clinton is for that. humanitarian corridors? should we bomb assad's helicopters so they can't drop the barrel bombs or is it too late? now that russian war planes are flying in the skies?
