I think it's quite clear now that if Iraq has WMDs, they are far more dangerous now than they were before the war. Weaponized anthrax, for example, is worth a lot more money than that art that disappeared, and I doubt that the military/secret police goons in charge of that stuff had many scruples keeping them from grabbing some and running off.

The best arguments for invading Iraq were that the Iraqi people, maybe, support the invasion, even from us infidels. WMDs weren't ever a good argument for invasion, as being something used on us. They were a marginal argument in the strategic game of asserting influence in the Middle East, which is a much trickier and more ethically opaque issue.

My opinion, FWIW, is Iraq's 90 percent likely to have some chem/bio weapons.
