Timothy Noah has an excellent run-down of a dove's quandry on Iraq. But even he failed to pick up on the possibility of Saddam supplying anthrax or nerve gas to a freelance al-Qaida cell in the not-too-distant future. No love is lost between Saddam and al-Qaida today but I think it is quite plausible for them to set aside their differences briefly to strike a blow against the US.
