I still wish someone would explain to me what the difference is between the not-so-dangerous sort of Uranium oxide that we already knew about Saddam having and the kind that can be made into a nuke.

Uranium enrichment is a complicated, expensive, and fucking LENGTHY process and there's a damn good reason the nuclear club has been so limited thus far. (Libya? Not until you're dead.) Because U-238 (which makes up 99.3 percent of Uranium ore in the form of yellowcake) and U-235 share identical chemical properties, our only hopes of separation are through mechanical means.
Uranium oxide is converted to a flouride gas, then passed through a series of extremely fine porous barriers at high speeds several hundred thousand times. Uranium tetrachloride is then passed through a magnetic field wherein U-235 is gradually separated. A gas centrifuge is then employed to separate the lighter from the heavier isotopes.
(It's known that Iraq procured some 300 tons of yellowcake from Nigeria in the 80's, which was subsequently accounted for by the UN following the First Gulf War. This is not the pretend yellowcake Iraq allegedly attempted to purchase in 2001.)
