“I will say that the decision to go in, in retrospect, almost all of us think that was a horrible mistake. …Now that we know that it cost a trillion dollars, and all of these years, and all of these lives, and all of this blood… all I can say is everyone I know thinks it was a mistake to go in now.”Fuller transcript at ThinkProgress, with two other GOP congressmen agreeing -- not only that the war was a mistake, but that Republicans generally agree about that.
It hasn't properly been appreciated in American politics that it's possible for us to start a really stupid war. The clearest way to rectify this is for people across the political spectrum to come to the consensus that we did.
I'm a little surprised by these guys' claims of consensus, and anyway I'd expect Republicans at a Cato foreign policy event to be unusually appreciative of the consistent antiwar libertarian position where you recognize that if our government really can't fix things at home, it's not going to be able to fix things in a strange country on the other side of the planet. (Chris Preble runs foreign policy studies at Cato, and the little I can see of his stuff is good.)
But however much it means, it's a good sign.
