Here's a salient paragraph, among many:
The habit of viewing Iraq as a crisis that only began in 2003--a lazy habit that is conditioned by the needs of the impending 2008 election--is an obstacle to understanding. Everybody has their own favorite alternative scenario of how things might have evolved differently or better. In some weak moments, I can picture taking the alternative advice from the European Union and the United Nations in 2003--let's just see how Iraq develops if left alone as a private fiefdom of the Saddam Hussein dynasty--and only then deciding that things have deteriorated to the point where an international intervention is necessitated. That would have been much less upsetting and demanding than the direct assumption of responsibility, and could have been triggered by the more familiar images of unbearable suffering and carnage, and could have summoned the Darfur-like emotions of guilt and shame, but it would perforce have been begun very much later--and perhaps too late altogether.
Or to remind all of the logical problem: asserting that the United States created the current mess with its invasion assumes the unlikely postulate that an equal or worse mess wouldn't have occurred had the US done nothing.
Mind your logic, all ye who blame Bush and the neocons and head for home.
