Of course just because people think that Blair and Bush were telling porkies, that wouldn't necessarily mean they oppose the war. And there could well be some people who don't think they were lying who were and are against the war.

They are different questions.

I get irritated at the assumption that it's ok to adjust our beliefs about matters of truth and falsity to match the way we'd like the facts to turn out. It seems to happen in issue after issue - for a classic example, the vote-counting issue in the US Presidential election.

True enough human beings have a tendency to do that kind of thing, but it shouldn't be shrugged off as inevitable. Honest people try to resist that kind of temptation.
