Well, I don't discount that the anthrax is still a threat. If we take the situation at face value -- Saddam, Uday, Qusay are all alive, at large, know where the biologicals are cached, have no fixed assets to play for, and every reason to want to revenge themselves on the United States -- then we are in deep doo-doo. Which is one of many reasons I don't take the story that we are clueless as to the whereabouts of Hussein at face value. My other reasons include that it is a priori logical for us to use the Russians to defuse the situation, and a priori logical for us to pretend we didn't know anything about it, that it is by now quite clear that the US has been lying to us about the so-called decapitation strikes, and more and more hints are surfacing that a Russian-brokered surrender is, in fact, exactly what happened. But, it is still "just a theory."
As to this "anthrax" case, I grow more convinced with each passing hour that it's a red herring. There are six billion people on this planet. Several million of them died of various causes during the Iraq campaign. How surprising is that someone, somewhere, went off half-cocked and misconstrued one of those millions of deaths as being connected with bioterrorism when it wasn't?
