and dimitri simes, president of the center for the national interest, a foreign policy think tank. michele dunne, let me start with you. what is going on? how serious is this diplomat conflict between the u.s. and the russians? >> well, there's been a lot of tension, of course, beeen e united states and for some time now over syria, and i think that the escalating situation within syria itself, even with the past couple of weeks, we've seen the level of brutality, the brutality against women and children, and the weapons being used. i mean, we're seeing now helicopter gunships used against civilian populations, bombardment of civilian populations, accompanied by atrocities by militias. all of this, i think, is putting the united states under extreme pressure and this is one of the reasons i believe secretary clinton called out the russians and said you're contributing to this by giving the syrians these kind of weapons. >> brown: dimitri simes, i see you've joined us. thanks for getting through the traffic to us. what do you make of what's going on with the russians and the u.s.? w
