little more info please.... if you are saying that the US and UK sold chemical and biological weapons to Saddam, I think you are going to have to come up with a bit more.
I know the Germans, French and Russians sold them equiptment to make the gas. I think an American company sold (illegally) a chemical that is nessasary to make the gas but they were a very minor participant.
It's old tech and fairly simple to make...
Let me know your opinion.....
