Disregarding your ignorant trollish comments, France, China, and the Soviet Union would be the ones that supplied Saddam with the majority of his weaponry, as noted by his majority soviet arsenal.
It gets more interesting when we see who supplied Saddam with chemical weapons. It turns out
Iraq got its start from German firms, The UK paid for a chlorine plant which provided him mustard gas, Brazil provided mustard gas before that plant was running, Singapore and India provided the ingredients for VX nerve gas, Egypt and Spain provided much of the means to disperse the chemical weapons,
and the US center for disease control,
in its naivette, provided Iraq with samples of diseases for Medical research and other similar purposes.
Here you go for conventional purchases
