Spencer Ackerman makes an interesting point:
Let's say Maliki did, at the stroke of a pen, "disband" [the militias], and let's also say that the militias comply. What happens? Exactly what happened in 2003 when Jerry Bremer abolished the Iraqi Army: thousands -- possibly tens of thousands -- of ruthless men with guns are out on the streets. Think they'll act with malice toward none and charity toward all?
Maliki doesn't have the power to do it anyway, says Ackerman, whose reports on subject like this used to be among The New Republic's few bright spots. But Ackerman's right -- if Maliki could do it, could it possibly make any difference? Where would these guys go? What would they do all day?
