At the time, Iraq's attitude was "The enemy of my enemy is my friend" and accepted our military aid. After we accidently shot down an Iraqi AirBus, we even were for a period providing Iraq with AWACS surveillance.
However, as signatory to the ban on Biological weapons, we at no time provided Iraq with Anthrax. We may indeed have supplied laboratory equipment that allowed them to grow and refine Anthrax, but this same equipment is also used in medical research.
