Corker says he'd wait on making a decision about Afghanistan troop withdrawal CORKER: I would wait, and I don't know of any reason why we would make that decision today. Haass doubts Afghanistan will be "self-sustaining" once U.S. troops leave HAASS: The idea that we're going to be able to leave behind a self-sustaining, capable Afghanistan able to - or a government that's able to keep control of its territory, we are not going to be able to do it. Haass calls Hagel anti-Semitism accusations "preposterous" HAASS: Where I think people are going over the line is with ad hominem attacks - questioning for example whether he's an anti-Semite. Corker wants to look deeper into the "one-liners" that have been said about Hagel CORKER: One of the reasons I want to spend time with Chuck Hagel is I think...there's been a lot of one-liners, if you will, that have been looked at, and I want to dig in and find out whether that really is Chuck Hagel's view of the world, or whether we're taking these things out of context. Reed defends Hagel, citing his "ability to speak truth to power" REED: I also understand that Chuck has the wherewithal and the ability to speak truth to power. Walker says GOP needs to "wake up and get real" on debt ceiling debate WALKER: Look, the Republicans need to wake up and get real. Ultimately as part of a grand bargain we ought to get rid of it....But in the interim, if the Republicans want to use leverage, they ought to use it on the sequester and the continuing resolution. 7.Krugman likens debt ceiling to "hostage taking" KRUGMAN: We should not allow this to become thought of as a legitimate or normal budget strategy. This is saying walk into a room saying I've got a bomb give me what I want or I'll blow up this room...You can negotiate on the sequester, you can negotiate on taxes, but not on someone who is threatening to blow up the world economy if he doesn't get his way. Noonan tells Republican party to take "daring and surprising" positions NOONAN: The Republicans are in a bad position right now...this is a wonderful time to be daring and surprising. Woodruff suggests Obama "take a line from Mitt Romney" to increase cabinet diversity WOODRUFF: Maybe they ought to take a line from Mitt Romney, binders full of women. Krugman says White House lacks "serious representation" of progressive economists KRUGMAN: I think it's frightening that at no point in this administration have there been any serious representation of what you might call the progressive economist wing which is a pretty big part of Obama's support.
