Back in February, Justin Logan pointed out that predictions of DOOM following an American departure from Iraq echo essentially similar predictions being made about Vietnam in the late 1960s. Now via Justin I see that Kurt Campbell and Shawn Brimley have a Foreign Policy article making the same point.
The difference, however, is that as best I can tell Campbell and Brimley read the lesson in the opposite direction. Brimley's one of the coathors, for Campbell's new think tank, of a memo (PDF) arguing we can't afford to leave Iraq. These guys are part of the "residual force" consensus to which the Democratic Party seems weirdly hostage.
