The Butler report said British intelligence had "credible" information -- from several sources -- that a 1999 visit by Iraqi officials to Niger was for the purpose of buying uranium:
Butler Report: It is accepted by all parties that Iraqi officials visited Niger in 1999. The British Government had intelligence from several different sources indicating that this visit was for the purpose of acquiring uranium. Since uranium constitutes almost three-quarters of Niger’s exports, the intelligence was credible.
The Butler Report affirmed what the British government had said about the Niger uranium story back in 2003, and specifically endorsed what Bush said as well.
Butler Report: By extension, we conclude also that the statement in President Bush’s State of the Union Address of 28 January 2003 that “The British Government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa” was well-founded.
The U.S. Senate Select Committee on Intelligence reported July 7, 2004 that the CIA had received reports from a foreign government (not named, but probably Britain) that Iraq had actually concluded a deal with Niger to supply 500 tons a year of partially processed uranium ore, or "yellowcake." That is potentially enough to produce 50 nuclear warheads.
The Senate report said the CIA then asked a "former ambassador" to go to Niger and report. That is a reference to Joseph Wilson -- who later became a vocal critic of the President's 16 words. The Senate report said Wilson brought back denials of any Niger-Iraq uranium sale, and argued that such a sale wasn't likely to happen. But the Intelligence Committee report also reveals that Wilson brought back something else as well -- evidence that Iraq may well have wanted to buy uranium.
Wilson reported that he had met with Niger's former Prime Minister Ibrahim Mayaki, who said that in June 1999 he was asked to meet with a delegation from Iraq to discuss "expanding commercial relations" between the two countries.
Based on what Wilson told them, CIA analysts wrote an intelligence report saying former Prime Minister Mayki "interpreted 'expanding commercial relations' to mean that the (Iraqi) delegation wanted to discuss uranium yellowcake sales." In fact, the Intelligence Committee report said that "for most analysts" Wilson's trip to Niger "lent more credibility to the original Central Intelligence Agency (CIA) reports on the uranium deal."
Committee Report: He (the intelligence officer) said he judged that the most important fact in the report was that the Nigerian officials admitted that the Iraqi delegation had traveled there in 1999, and that the Nigerian Prime Minister believed the Iraqis were interested in purchasing uranium, because this provided some confirmation of foreign government service reporting.
I said: the report from her husband, Joe Wilson, that the administration's claim that Saddam Hussein's Iraq had sought to purchase uranium from Niger was a bunch of hooey....
Was Wilson's claim that the Bush administration lied about Hussein trying to buy uranium false or not? Everything I heard (outside of the MSM) was that Wilson is a lying sack of crap.
