Kevin Drum is setting his standard for the war as swimming pools of anthrax. As I mentioned previously, I could care less about most chemical and biological weapons. The level of danger simply isn’t that great and other regimes were more likely to supply them to terrorists.
The exception being smallpox. If we don’t turn up evidence of a nuclear program and/or smallpox, this war was pointless. Nukes are the only real WMD and if he didn’t have an active program (and I believe he did), containment would have worked just fine, thank you.
