CarolC, My point was that sometimes Experts find what they are supposed to find, and make their assesments from flawed information. As for purchasing chemicals, it would be too simplistict to say that the USA is/was the only source of chemicals. Far more dangerous substances can be purchased from mercenary suppliers worldwide, and we know Iraqs former leader had no scruples in using illegal weapons. Quite frankly the military surplus store formerly known as the Soviet Union scares the hell out of me even today.
