Yes? That was, after all, concretely the claim made by the administration before the invasion (recall the joke by Dave Chappelle about yellow cake)

There's also plenty of evidence that Iraq had (known, small) stockpiles of chemical weapons, too (last I checked those were classed as WMD), which are widely accepted to be a likely cause of gulf war syndrome and a contributing factor to congenital disease in some parts of iraq.

Mind you: I'm not claiming that it's ethical to invade a country on shoddy pretenses.

If you are thinking about the fear of contraband imports of yellowcake, well none of that has ever been found and its highly unlikely to have existed. The removed yellowcake had been stockpiled prior to the first Gulf War, and was declared to the International Atomic Energy Agency and under IAEA safeguards.

Of course at one old point Iraq had WMD programs. But you were completely misrepresenting the situation by stating for the later period that "The funny thing about that conspiracy is that the WMD were real. Hussein had them, and and its true that he didn't give them up". Even the very article you linked stated clearly: "There was no evidence of any yellowcake dating from after 1991, the official said." As for the small amount of chemical weapons or precursors, they also have not been interpreted afterwhile has having any significance regarding the willingness to comply.
