the smoking gun?

The United States has found 500 chemical weapons in Iraq since 2003, and more weapons of mass destruction are likely to be uncovered, two Republican lawmakers said Wednesday.

"We have found weapons of mass destruction in Iraq, chemical weapons," Sen. Rick Santorum, R-Pa., said in a quickly called press conference late Wednesday afternoon.

Reading from a declassified portion of a report by the National Ground Intelligence Center, a Defense Department intelligence unit, Santorum said: "Since 2003, coalition forces have recovered approximately 500 weapons munitions which contain degraded mustard or sarin nerve agent. Despite many efforts to locate and destroy Iraq's pre-Gulf War chemical munitions, filled and unfilled pre-Gulf War chemical munitions are assessed to still exist."

... a senior Defense Department official pointed out that the chemical weapons were not in useable conditions.

"This does not reflect a capacity that was built up after 1991," the official said, adding the munitions "are not the WMDs this country and the rest of the world believed Iraq had, and not the WMDs for which this country went to war."The official said the findings did raise questions about the years of weapons inspections that had not resulted in locating the fairly sizeable stash of chemical weapons. And he noted that it may say something about Hussein's intent and desire. The report does suggest that some of the weapons were likely put on the black market and may have been used outside Iraq.
