To this day we keep hearing that supposedly "everybody" or "virtually everbody" agreed with Bush and Cheney's statements regarding Iraq's "vast stockpile" of WMD.
The claim is bunk. There was considerable disagreement.
During the same time period in which Cheney and Rumsfeld were running around claiming that there was "no doubt" that "Saddam Hussein now has weapons of mass destruction"* and "chemical and biological weapons,"** their own intelligence experts were telling them something different.
U.S. News & World Report in its June 9, 2003 edition revealed the existence of a September 2002 intelligence analysis by the US Defense Intelligence Agency (DIA) titled "Iraq: Key Weapons Facilities -- An Operational Support Study." This DIA report stated that "there is no reliable information on whether Iraq is producing and stockpiling chemical weapons, or whether Iraq has -- or will -- establish its chemical warfare agent production facilities."
This DIA assesssment noted that "a substantial amount of Iraq's chemical warfare agents, precursors, munitions, and production equipment were destroyed between 1991 and 1998 as a result of Operation Desert Storm and UNSCOM actions."
The report speculated that Iraq "probably possesses [chemical weapons] in chemical munitions, but that "we lack any direct information" on thsi subject.
That's a far cry from Cheney's claim that "there is no doubt."
