"Saddam did use WMD against Irananian human wave attacks during the Iran/Iraq War."
which he received compliments of the first Bush Adminstration. The question still remains, were they destroyed during the UN inspections? i think the answer is yes. The Bush the First thought that supplying WMD's to Iraq would deter Iran as analogous to the support for Hitler against Stalin in the late 1930's.
This explains why Bush and Reagan supported Saddam and gave him WMD's.
The recent so-called discoveries of WMD's were outmoded weaponry that had degraded since 2003 and are of no potent use. It's a red-herring.
