History is just tough stuff, the true story often gets hidden in revisionist nonsense that goes for history today. Everyone knew he had chemical weapons, one could make them in the kitchen.
"The Ties That Blind - How Reagan Armed Saddam with Chemical Weapons" By Norm Dixon
"On August 18, 2002, the New York Times carried a front-page story headlined, "Officers say U.S. aided Iraq despite the use of gas". Quoting anonymous US "senior military officers", the NYT "revealed" that in the 1980s, the administration of US President Ronald Reagan covertly provided "critical battle planning assistance at a time when American intelligence knew that Iraqi commanders would employ chemical weapons in waging the decisive battles of the Iran-Iraq war". The story made a brief splash in the international media, then died."
Norm Dixon: How Reagan Armed Saddam with Chemical Weapons
"On March 18, 2009, Attorneys Kenneth J. McCallion of McCallion & Associates, Jeffrey D. Katz of JDKatz, P.C., and Stanley Todman of OffutKurman, P.A., filed suit against the Government of Iraq,
and four US chemical companies as a class action on behalf of the the victims of the Gas Attack. The case was filed in the US District Court for Maryland, and is styled as Aziz v. Iraq. This was the first and only known action brought against the Government of Iraq and the manufacturers of the chemicals involved in the poison gas attacks. The case was subsequently dismissed by the US District Court, and is presently on appeal in the Fourth Circuit. A ruling is expected in February, 2011."
