STRATEGYPAGE lists the top ten myths of the Iraq war:

4-The United States armed Saddam. This one grew over time, but when Iraq was on its weapons spending spree from 1972 (when its oil revenue quadrupled) to 1990, the purchases were quite public and listed over $40 billion worth of arms sales. Russia was the largest supplier, with $25 billion. The US was the smallest, with $200,000. A similar myth, that the U.S. provided Iraq with chemical and biological weapons is equally off base. Iraq requested Anthrax samples from the US government, as do nations the world over, for the purpose of developing animal and human vaccines for local versions of Anthrax. Nerve gas doesn’t require technical help, it’s a variant of common insecticides. European nations sold Iraq the equipment to make poison gas.

You’ll have to go there for the other nine.
