I mean the Bush administration was warned that the Niger uranium documents were forged. There was no evidence that Sadaam had acquired uranium from Niger.

Very good point.

The 1,000,000 lb of refined yellowcake found in nuclear research center of Al—Tuwaitha in Iraq came most likely from Russia.

Upon further research, I was wrong.
~260 tons of Uranium dioxide came from Portugal
~200 tons from Nigeria
~ 28 tons from Brazil
~ 12 tons from Italy

All those aquisitions were quite old. Early 80's... From the IAEA's Fact Sheet above we can see the following.

"
As of 16 December 1998, the following assessment could be made of Iraq's clandestine programme:

There were no indications to suggest that Iraq was successful in its attempt to produce nuclear weapons. Iraq's explanation of its progress towards the finalisation of a workable design for its nuclear weapons was considered to be consistent with the resources and time scale indicated by the available programme documentation.

Iraq was at, or close to, the threshold of success in such areas as the production of HEU through the EMIS process, the production and pilot cascading of single-cylinder sub-critical gas centrifuge machines, and the fabrication of the explosive package for a nuclear weapon

There were no indications to suggest that Iraq had produced more than a few grams of weapons-grade nuclear material through its indigenous processes.

There were no indications that Iraq otherwise clandestinely acquired weapons-usable material

All the safeguarded research reactor fuel was verified and fully accounted for by the IAEA and removed from Iraq.

There were no indications that there remains in Iraq any physical capability for the production of amounts of weapons-usable nuclear material of any practical significance.
