As Neal promised a week and a half ago, it's time to check in on the so-called troop "surge" in Iraq. (For more on how the "troop increase" became a "troop surge," go here.) The president's plan to increase force levels in Iraq by about 30,000 troops was the subject of an emotional debate in the press, and even a marathon debate in the House of Representatives, ending in a resolution protesting the increase. Now that about half of the troops requested are now in Iraq (with the remainder to be deployed in June), it seems a good opportunity for a progress report. So far, it depends on whom you ask; the president and other proponents of the surge have cited Baghdad bloggers who claim that things are better, but it's been a bloody week in which 500 Iraqis and 6 American soldiers were killed, putting military officials on the defensive again. We'll check in with retired Army General Jack Keane: in his opinion, the troop increase was not only necessary, but the only option not doomed to failure. He's just returned from Iraq, and has a report on how it's going.
