there. what's very interesting about this conversation, a couple of things. for weeks now the white house had been pretty putin insisting the russians would -- president obama noted that vladmir putin that the russians thad been taking strikes against isis in jar. not really making that accusation that russia is trying to prop up assad. the other thing coming out of white house is these two leaders, president obama and putin agreed on a syrian lead transition away from asad. that's notable as well because the white house has maintained for a long time and been sharply criminal that putin is in syria to help out his buddy assad.
