This whole thing stinks. The IAEA supposedly tagged 500 tons of uranium, 1.8 tons were enriched to a low level. This uranium was stolen from Tuwaitha, the uranium dumped out and the barrels sold and used for drinking water? And we only found at the time of the report 100 of 3000 barrels? How do we know this was all tagged uranium? And again, why didn't the IAEA take out the uranium when we had inspectors in there before the war? So many questions.
If nothing else, it shows sloppy work with little oversight and provides evidence for an organization which really doesn't care so much about who has what.
According to Richard Miniter in his book Disinformation, on June 23,2004 U.S. forces seized 1.77 metric tons of enriched uranium(partially enriched). U.S.Dept. of Energy experts also removed 1,000 radioactive materials in "powdered form" which is easily dispersed. The material would have been ideal for a radioactive dirty bomb.
Miniter has other WMD discoveries in his book.
