We’re just a few weeks away from a milestone I suspect most of Washington would like to forget: the start of the Iraq war. What I remember from that time is the utter impenetrability of the elite prowar consensus. If you tried to point out that the Bush administration was obviously cooking up a bogus case for war, one that didn’t bear even casual scrutiny; if you pointed out that the risks and likely costs of war were huge; well, you were dismissed as ignorant and irresponsible.
