These were all acts of agression justified by the logic of the individuals that committed them. When the logic is rationalized by misleading the public to approve the actions, this is when the problem gets out of hand. This is where the Bush administration made its mistake. If you cannot make a reasoned argument for your actions and have to rely on mistruths to make your case, you are treading on pretty thin ice.
It is going to take a pretty good period of time for Bush and his entourage, plus some honesty, to regain the trust of the public, here and overseas. Trying to weasel out of it by blaming the intelligence community will not do it. A direct apology to the American people and the families who lost love ones in a cooked up war would be a good start.
