But didn't the IAEA inspectors allow that? If Bush used that for a reason for war, it's pretty bad, since it was known for a decade and his father would have been to blame.
If they can't show overwhelming evidence of post Gulf War '91 WMD weapons, materials, programs, research, etc. then they just quietly ignore these things as they are found.
Never mind whether it was illegal or had been hidden but people just see it was obtained in the 80's or what have you and laugh it off.
