NOAH SHACHTMAN IS BLOGGING FROM IRAQ: “Meet the new defenders of the city of Fallujah. For years, the Marines have been trying to behead the insurgent hydra that’s been terrorizing the people here. Now, they’ve got a plan that, for the moment, seems to be working. Attacks on American troops are way down; the streets are relatively clean; men are sitting around in outdoor cafes.” Let’s hope it lasts.
