"All of the weapons found, however, were produced prior to 1991 as part of a crash program started in the 1980s and meant to be used against neighboring Iran during an eight-year war between the two countries. "In five of six incidents in which troops were wounded by chemical agents, the munitions appeared to have been designed in the United States, manufactured in Europe and filled in chemical agent production lines built in Iraq by Western companies," the Times says."
So there were WMDs. Case closed.
