Reply #177: The most damning logic imo is this (and it supports this theory):

1) The administration knew that the WMD intel wasn't fully accurate. (Info taken out of Fall '04 speech)

2) Yet, somehow, they appeared completely convinced they would find WMD evidence. Quotes like "We know they've got them", "We know where they are", and "We found them" all show a complete lack of acknowledgement of the known doubts of the intel.

Yes, the WH has a grand history of lies. But, our country is not yet to the point where this is tolerated. Some "proof" of the lie must be uncovered or spun the right way in order for it to be accepted. Obviously, the best follow-up to a national lie such as this is to make sure it could be backed up, at all costs. If they knew the WMD intel was doubtful, the only reason they could be so confident of evidence being found was that they would have a hand in creating it.

Now, this is speculation, but it makes complete sense:
They tried to create the WMD evidence, but they failed. They had to fall back on the spin angle, and re-adjust their "true" motives for war, i.e. a free and democratic Iraq, Iraq-Al Qaeda connection, "fight 'em there, so we don't have to fight 'em here", etc....
