Just listened to ABC news at 9 pm on the radio.This is what they said.Martha Radditz(sp?) said that there was a big discrepancy between what the Iraqi said was there in March 2002 140 tons and what the IAEA say was there in Jan 2003 3 tons. They were talking about RDX.
This is from the NY times article : http://www.nytimes.com/2004/10/25/international/middleeast/25bomb.html?ex=1099368000&en=9ce7b708a2986170&ei=5065&partner=MYWAY
and shows the 141 metric tons of RD and 194 metric tons of HMX in 2002, along with 6 tons of other (totaling 341 metric tons or roughly 376 "normal" tons)
