] Any actual WMD weapons or material is likely to be small in

] difficult to near impossible to identify with normal search

] We have discovered dozens of WMD-related program
] activities and significant amounts of equipment that Iraq
] concealed from the United Nations during the inspections

] deliberate concealment efforts have come about both
] through the admissions of Iraqi scientists and officials
] concerning information they deliberately withheld and
] through physical evidence of equipment and activities
] that ISG has discovered that should have been declared to
] the UN. Let me just give you a few examples of these
] concealment efforts . . .

There's an extensive list here of specific things found as of October 2003. Many many items which clearly should have been declared to the U.N. inspectors, which were not.

Iraq was systematically and provably hiding things, and any Democratic candidates who try to say that this all was just "made up" by Bush are being hypocrites.
