Since, atypically, this appears not yet to have been mentioned by any of my on-the-news Atlantic.com colleagues, let me refer anyone who has not seen it to the full text of Col. Timothy Reese's memo urging a rapid exit from Iraq, "It's Time for the U.S. to Declare Victory and Go Home." I first saw it this morning at the Washington Independent site, here, and recommend the full thing to anyone who has read only news summaries.
Opinion has always varied widely within the professional military about the prospects and best options for America's presence in Iraq. So this obviously does not represent a new military "consensus." But it makes a big difference to have this case argued by a senior U.S. military officer on the scene. Well worth reading.
