Not listening to reason
I think I have more respect for James Baker now.
Perhaps what really happened is that Bush seized on a way to get the public to pay for his oil grab in Iraq. By using our military, and some nationalistic jingoism, he was able to go in strictly from a business point of view. It didn't hurt that he had a Vice-President and several old Defense officials who owned a lot of reconstruction companies and who could be handed the contracts.
The only way we could find out for sure, is to uncover the secrets of his "energy meetings" with oil execs and others several months before the invasion.
