Julian's response to Megan McArdle (and, by extension, Jon Chait) is a perfectly devastating rebuttal to the hawks now averring that the doves were right for the wrong reasons, or were too right to be trusted in the future. Plus, it has some great milkshake imagery.
Meanwhile, so far as Chait's odd column decrying the pernicious opinions of everyone who got the war right goes, it's worth noting that he adds, as an afterthought, (in the way we all used to have to say "Saddam is a murderous tyrant"), that "[t]here are many lessons to be absorbed from Iraq. We'd be foolish not to absorb them; only the most dense war supporter has come away from the experience unhumbled."
Funny. Jon's column doesn't seem terribly humbled. And how did that quoted bit get shunted to the end of the article? Chait is, I'm willing to believe, a quick learner, so maybe his period of study was very quick and very quiet, and he's now learned enough that the discredited teacher-cum-student can again return to the head of the classroom. But it's sort of a remarkable trick the hawks pulled off. They got Iraq wrong, now say they've learned their lessons, and have begun replaying their tapes from 2002.
Well, at least they recycle.
