I never thought I'd so vehemently agree with an entry on Huffington Post but, here it is.

 I lived in Baghdad from April 2003 through September 2004, when I left without, of course, really leaving...

Those who opposed the war seem to feel that they are the perfect opposite of those who sold the war - and of course, in the important sense of the invade-or-not-to-invade question, they are. But in their collective allergy to any fact that may complicate their position; their proud blindness to the color gray, and their fervent faith in their own infallibility, the two sides have always struck me as very much the same.

...what depresses me, and makes me despise so much war criticism even when I agree with it, is that so many of those positing it seem so happy about what's gone wrong. They seem to relish the probability that Iraq will get worse and worse so that they can be righter and righter.

and it gets better from there.
