P.S.
Iraq has a known and proven history of enthusiastically attempting to construct nuclear, biological, and chemical weapons. After their first attempt at nuclear warheads was flattened by Israel, they started another, more secretive program. That one was disassembled by the U.N. after the Gulf War flattened Iraqi resistance to the process.
I see absolutely no reason to believe that Saddam would suddenly change his ambitions after two attempts in the face of massive world resistance. And that's just the nuclear stuff.
Remember, whatever current WMD program they had would have been designed to avoid years of U.N. inspectors. They can't be easy to find.
