I wonder if the UN oil-for-food scandal has something to do with all this also. The embargo really didn't stop France, Germany, and Russia from making a profit smuggling arms to Saddam. Saddam had his public relations coup (US killing children.) UN folks and Saddam both making money hand over fist. The gravy train might end if the WMD were known to be destroyed.
I suspect Saddam had a deeper game going. He was continuing work, mostly through France. There were barrels and barrels of precursor finds with French labelling.
