Don’t get too excited over the 500 tons of yellowcake - Iraq admitted to having it years before the war - it acquired in in the late 1980s- and the IAEA put it under seal when they began inspections after the Gulf War.
While a lot of people pointed to it and said “aHA!” it was not a “See, I told you so” find.
Of more import was Iraq’s reconstruction of old facilities, construction of new facilities, inquiries into purchasing additional unsealed uranium, purchase of tubing for centrifuges, mobile labs, preservation of pathogen strains, retention of documents, blueprints and prototypes for centrifuges, the activities of its scientists in Libya, the fact that its long range missile development program was well ahead of what our intel suspected, its drones and spraying devices, and so on.
