once assad crossed a line that the administration properly felt the world had to respond to, i think it illuminated how big a gulf separated the two sides. now you are seeing the dashed expectations of president trump and president putin of what is possible in the harsh light of how much our interests diverge in syria. it is not just the interests. carol, you have the white house struggling with the message and line they will tolerate in syria. certainly believing they had actual intelligence of the chemical weapons attack. the russian president says he has two theories for what happened. one, a near miss of rebel munitions and the other is it is completely fake. how do you bridge that gap? it will be difficult to bridge that gap.
