Bob's Blog: Syria takes the center stage

This situation in Syria just has so many moving parts. Last weekend, the president was gearing up to urge Congress to give him the authority for a strike. Then, he backed away from that and said the Russians wanted to work with us to find a diplomatic solution to all this.

I think it would have a been a blow to the U.S.'s credibility for the President to draw a red line and then have military action voted down in Congress. That move would have left the United States in a very vulnerable position. If Congress were to cut the President's legs out from under him like that, I think that would have undermined the United States among friends and foes alike.

But what's important here is that this is the first time Russia or Syria has even admitted that Syria has these chemical weapons. I think that's a step in the right direction.

Sunday on "Face the Nation" we'll be talking about all of these moving parts in Syria. We have the Senate Armed Services Committee Chairman Carl Levin, D-Mich., plus the ranking Republican on the Foreign Relations Committee, Bob Corker, R-Tenn. We'll also hear from former Secretary of State Madeleine Albright. I'm interested to hear where these three think about where this thing is going, because right now it seems to me that it go anyplace.

We'll also have analysis from Harvard University's David Gergen, The Washington Post's Michael Gerson, The Wall Street Journal's Peggy Noonan, and Susan Page of USA Today. Plus, we'll have a special preview of John Miller's "60 Minutes" interview with former CIA Deputy Director Michael Morell. Hope you'll tune in. Check your local listings.
