The WMD aspect of the argument in 2002 was not whether Sadaam would use it on us, but that he would give WMDs to terrorist organizations to use on us.
That was how you and I saw it, and how some conservative pundits saw it, but the media has always searched for stockpiles of WMDs to be used on the US. If they were to truly focus on very small quantities in aerosol delivery, they scare Americans to their core.
