In June 2006, Santorum declared that weapons of mass destruction (WMDs) had been found in Iraq. Santorum's declaration was based, in part, on declassified portions of the U.S. Army Intelligence and Security Command. The report stated that coalition forces had recovered approximately 500 weapons munitions that contain degraded or vacant mustard or sarin nerve agent casings. The specific weapons he referred to were chemical munitions dating back to the Iran–Iraq War that were buried in the early 1990s. The report stated that while agents had degraded to an unknown degree, they remained dangerous and possibly lethal. However, officials of the Department of Defense, CIA intelligence analysts, and the White House have all explicitly stated that these expired casings were not part of the WMDs threat that the Iraq War was launched to contain.

Those two words go together like Oil & Water.
