“Huh? There were plenty of WMDs in Iraq. Stocks of yellowcake, tons of chemical munitions.”
Yellowcake is hardly the scary threat that you’re pretending it is. If you have $29 you can buy yourself a gram. Just don’t eat it.

99% of it is U-238 and that’s not even radioactive enough to make a decent dirty bomb, much less an actual nuclear fission bomb.
The U-238 that makes up the vast majority of yellowcake is non-fissile and cannot sustain a chain reaction. You need something to sustain a chain reaction or you don’t have a bomb. Something like U-235.
Yellowcake is a first step in processing uranium ore before it is enriched. Nothing has been done to concentrate the tiny amount, 0.7%, of U-235 in the natural ore.
That’s a long way from even the low enriched uranium of 20% U-235 that is used as reactor fuel.
Weapons grade uranium is 85% U-235.
