Of course it had a history. That history is what you are trying to rewrite. It reads very much like a lot of ugly history: the arrogance of power misleads someone into thinking they could come off as a conquering hero.
Bush was easily swayed by neo-con advisors into thinking it would be easy, easier than GW I. He could clean up his dad's mistake. He could get some revenge for 9-11. It all plays a part.
