I have to agree with Matthew Yglesias here on the recent spate of (formerly) highly placed Republicans—Scowcroft, Wilkerson, etc.—coming down hard on the Bush administration. It's certainly nice to hear, but where the hell were these guys last year? Protecting their asses, that's where.
As Matt points out, they saw what happened to Richard Clarke, and they were scared. But if they had some balls, they might have made a difference in the things they're now complaining about, instead of just becoming best-selling authors.
