maybe what we have found so far is the component parts of binary chemical weapons
They need to be mixed with other components before they are "weaponized".
I am surprized that we haven't found biologicals yet...But remember, Sadam located most of his WMD facilities near Tikrit where the locals were not likely to rise up against his regime.
My fear is that just when we thought the war was winding down, that the last surviving elements of the Baath Party will decide to go out with a chem/bio bang.
