This is one of the more obvious ones for me. Ye old Niger debacle.

Condi: "My only point is that, in retrospect, knowing that some of the documents underneath may have been--were, indeed, forgeries, and knowing that apparently there were concerns swirling around about this, had we known that at the time, we would not have put it in. . . . And had there been even a peep that the agency did not want that sentence in or that George Tenet did not want that sentence in, that the director of Central Intelligence did not want it in, it would have been gone."

Ms. Rice was responding to questions regarding how the claim that Iraq sought uranium in Africa made it into the President's January 28, 2003, State of the Union address. The statement that the Director of Central Intelligence and the CIA did not object to the claim was false. In October 2002, the CIA expressed doubts about the claim in two memos to the White House, including one addressed to Ms. Rice. Director of Central Intelligence George Tenet also warned against using the claim in a telephone call to Ms. Rice’s deputy in October 2002.


>There has also been evidence that mass shipments took place via rail from Iraq to Syria just before the U.S. invasion. No proof of what those shipments contained though without having access in Syria. Are you stating that you know for a fact that those shipments didn't contain anything related to wmd? The interviews the military held with the guys working the train was interesting. They pretty much stated that everyone knew what was on the train but no one looked and everyone walked off the job when the trains went through as instructed. There are just too many unanswered questions. I have not seen any report or documentation that proves that the leadership knowingly mislead the American public and knew or changed the intelligence reports to make the Americans believe there were wmds in Iraq when the administration knew there were not. Foreign intelligence sources that we relied on in the past stated there were. What proof or documentation can you point me to that shows that the
>leadership knew there were no wmds? Did Colin Powell know that?. Did GWB? Do you have information I do not or are you only assuming that to be the case? I think you are believing the hype once again and restating comments with no facts to back it up. Besides, it is documented and proven that Iraq used wmds in the past so it is indeed true that Iraq had wmds. The question is where did it all go.

>>There was no credible evidence of WMD in Iraq. None. Zero. The UN task force looked for close to a year and didn't find a firecracker. But the guys with itchy trigger fingers who have been bungling (apt word) this country for 6 1/2 years were determined to start a war anyway and they did.
