Yeah, but since the casus belli was ALWAYS OBVIOUSLY bogus, that's on them. Saddam held the world dicatatorship record for "number of times deterred as a rational actor after a little brinksmanship". He could have had the keys to the Russian arsenal and still not nuked anybody. Someone can say, with integrity, that they thought Iraq was a good strategic decision aside from the WMD nonsense, and can even say with integrity that they still think it was. Saying "Oh, I believed the intelligence and thought he was an imminent threat" is admitting up front that you can't read past the first 5 words of a headline.
