I think in response to the Mistakes question, Bush should have said:
"My worst mistake was to have any faith that the UN would do anything, and I should have known that members of the Security Council were being paid under the table by Saddam in return for stonewalling, and that Kofi Annan and his UN culture of corruption was making billions of illegal gains from oil-for-food, which was money that was supposed to be used to help the children and families of Iraq,
and that the delays caused by the UN resolutions enabled the Russians to assist Saddam in hiding his WMD in Syria and elsewhere where they remain a threat to the developed world today.
Other than that, I'm fine with what happened after we decided to ignore the pansies in the UN and Tony and I with the help of some other brave countries took that assh@le Saddam out and whipped his butt, and his sadistic vermin kids too.
Would you like a followup question?"
Hehehehe. I would literally pay money to have heard that, Rob.
