In last night's speech to the American people, President Obama laid out his case for punishing Syria's alleged use of chemical weapons to kill its own civilians. He asked every member of Congress, and those watching at home, to view shocking pictures of children writhing and dying, alleged evidence of Syria's use of chemical weapons. In addition to the moral argument, the President said there's a real risk to national security. But he asked Congress to postpone approval for limited military action -- a vote he was almost certain to lose. Instead, he said there's a chance of accomplishing his objectives without force, by negotiating a deal proposed by Russia. Did the President make the alternatives clear? If diplomacy fails, will the President renew the threat? What about Congress?
