You are stretching really hard to call Bush a liar.
You said, "then I think we can accept these judgements as fact, and make the deduction that the president presented information which was known to be false in order to support his case that Iraq was trying to acquire nuclear material."
We can? I don't think so. Davin would have killed me on this one had it been something had I posted something like this about something he opposed. You can make all the assumptions you want, come to all the conclusions you want, but don’t call the president a liar unless you have some real evidence.
