I will tell you why I believe Bush lied. I followed the debate fairly closely in the press and on TV. Unfortunately, I failed to keep notes of every day's events, particularly who said what on a day-to-day basis. And unless I'm going to write a book on the subject, I don't intend to go back now and research the day-to-day pronouncements of the Bush administration. So quite frankly my conclusions that Bush lied are based on my own recollection of the events preceding the war and certain facts that came to light after the event (the PNAC story primarily, some analyses of the event, particularly the one that pointed out Saddam's declared intention to price crude oil sales in euros and revelations of the immediate aftermath of 9-11 when Bush and some of his Cabinet members were particularly eager to implicate Iraq.)
What's my recollection? Very simple: Intelligence reports were accusing Iraq of possessing and/or developing WMD. There was a U.N. inspection program meant to detect such efforts, but Saddam was frustrating the inspectors. A UN resolution was passed requiring Saddam to "account for" all his WMD by a certain deadline. Saddam complied, a few days short of the deadline. The accounting was fairly massive, IIRC about 75 spiral-bound volumes of print and I believe 12 CDs of data. The general consensus of most UN members, except for the U.S. and the U.K. was that, given the number of years that Saddam had had a WMD program and the number of weapons involved, the accounting given by Saddam was about as complete as could humanly be expected. The U.S. and U.K. were not satisfied with the accounting and claimed Saddam was non-compliant. The U.S. drafted a Security Council resolution authorizing use of force but failed to put it to a vote when it realized that the other Security Council members (Britain only excepted) would not vote for it. Then they invaded anyway.
In the argument leading up to the invasion, I recall the following statements being made, either by the Bush administration or by administration-friendly columnists (Judith Miller of the New York Times standing out particularly in my mind) presented as coming from administration sources and allowed to stand uncontradicted by the administration: -
1. That the urgency of the situation would not permit giving the UN inspectors more time to finish the job
2. That the evidence of Saddam having the WMD was clear and unequivocal
3. That Saddam had a nuclear weapons program
4. That Saddam was crazy enough to either use the WMD against the U.S.A. or hand them off to unspecified "terrorists" to use on the USA
5. (Specifically, by Condoleeza Rice): That the search for the evidence could not be allowed to continue until the smoking gun turned into a mushroom cloud.
Those are my recollections of the public debate. No, I'm not going to go back and research a source for each one of them. If I'm wrong, I'm wrong but it's impossible for me to be wrong on each and every memory I have of the public debate. I got most of it and I got the gist of it: there was a terrible danger to the USA presented by Iraq and only swift and drastic action could remove it.
I did not separate out (except in the case of the mushroom cloud remark) who in the administration said what. I don't even separate out what was said by the administration and what was said in the press - - to do so would be very naive and foolish, simply because today the administration has many ways to get its message out, and press leaks to friendly journalists are just one of them. When a public debate is in process edging towards war and important journalists, claiming to have heard the story through administration or intelligence sources add to the debate by circulating powerful pro-war stories, the administration can choose to deny such material or let it stand uncontradicted. Whatever action the government takes with regard to such stories (and silently standing by is an available option, it's also an action) is a contribution to the overall message, either for or against.
I regard most of the above statements made not only as lies, but as obvious, plain-faced and bald lies. It was apparent to any thinking observer that there was no way in hell that the Iraqi government and all its weapons could pose any threat at all to the U.S.A. that wouldn't have involved minimal damage to the U.S. and total anihilation for the Iraqis. So the issue of what weapons the Iraqis actually had was a non-issue, a distraction and a farce.
Further, the evidence at the time was far from clear and a close examination of it would have revealed, for example, that some of it - - the yellowcake purchase letters for example - - were crude forgeries. The failure to detect crude and obvious forgeries, particularly on documents which were referred to in a State of the Union speech on the issue, is a glaring example of a carelessness which is absolutely incompatible with a genuine search for truth in intelligence. In other words, this information was received with other information without critical examination of any kind, which indicates not carelessness - - it's inconceivable that any administration interested in getting to the bottom of the WMD story would accept unscreened and unexamined evidence - - but a predetermined conclusion that Iraq was to be invaded. If anything came up that said "WMD present" they just did not want to examine it any further. Otherwise, had they examined it further, the forgery was easily detected. Similarly the "failure" to trace back most of the "intelligence" relied on by Bush to its single source - - the Iraqi National Congress, the one organization (apart from the big oil and contracting companies) with the most to gain from an invasion. Source is a key component, obviously, in evaluating intelligence - - it's just unbelievable that "carelessness" was the reason why no such analysis was conducted prior to the invasion. The scale of "carelessness" required for this massive "failure of intelligence" is compatible only with a desire not to know, a desire to use any superficially plausible piece of "intelligence" as a tool to justify a predetermined policy.
As in any other crime, we also have motive - - the PNAC policy papers, originally shown to the Clinton administration in the hopes of convincing them to invade Iraq. PNAC, a creation of Cheney, Wolfowicz, Perle and Rumsfeld, the people closest to the "President" in his policy deliberations, had already determined BEFORE Sept. 11 to invade Iraq.
So I say connect the dots. If any of you recall something much different than I do concerning the run-up to the Iraqi war, then by all means find a different conclusion. To anyone who remembers the events more or less as I do, I say: add in what is now known of PNAC, the names of its members and founders, their relationship to the "President," their early attempts to sell the Clinton adminstration on an invasion of Iraq) and - - forgetting completely about Saddam wanting to price oil in euros, forgetting completely about the post-911 Cabinet meetings, that's just the icing on the cake - - Just. Connect. The dots.
