@briansol,
Well, the report said that bin Laden was angry with the U.S. presence in the Middle East and that was why they said 9-11 was because of U.S. presence in the, but IMO, that doesn't mean it wouldn't have happened without it. bin Laden is a religious fighter and objects to infidels as a whole, being angry, of course, if they are in the Middle East.
And Giuliani was angry that Ron Paul supposedly said something about Iraq, if Ron Paul didn't, why would you attack Giuliani for misunderstanding him?
