where is the proof that the US supplied chemical weapons to Hussein? unless you can back that argument up, you fall in line with all of the others that have jumped on the unfounded conclusions bandwagon on this or any other issue.
Back in the 80's we sold different samples of chemical and biological agents to Iraq for research purposes only. At the time this was lawfull for the US to do and the samples sent were small and not weaponized. Saddam then had them reproduced into large quantities and weaponized using equipment and processes showed to Iraq by the Soviet Union. The Soviet Union also supplied many weaponized versions of chemical and biological agents they had produced. The Soviet Union was the largest producer of chemical and biological weapons in the world and to this day still maintains the largest known stockpile of such weapons.
