I believed that Iraq had probably tried to obtain weaponsgrade plutonium, and I knew that it had actually obtained centrifuges from Germany, as well as the means to manufacture chemical and biological weapons from Germany and the US. I surmised, from a position of total scientific ignorance, that Iraq probably possessed most of the ingredients necessary to manufacture weapons of mass destruction, but that it was some way off from actually doing so.
