"We have not yet been able to corroborate the existence of a mobile BW production effort. Investigation into the origin of and intended use for the two trailers found in northern Iraq in April has yielded a number of explanations, including hydrogen, missile propellant, and BW production, but technical limitations would prevent any of these processes from being ideally suited to these trailers."

In other words, they haven't concluded that the trailers were used for BW (biological warfare) production. Indeed, they state that "technical limitations" would prevent the trailers from being "ideally suited" for BW production.

And then there's this little gem about chemical weapons production:

"Multiple sources with varied access and reliability have told ISG that Iraq did not have a large, ongoing, centrally controlled CW program after 1991. Information found to date suggests that Iraq's large-scale capability to develop, produce, and fill new CW munitions was reduced - if not entirely destroyed - during Operations Desert Storm and Desert Fox, 13 years of UN sanctions and UN inspections."

In other words, Hans Blix was right on target.
