But yes, he did some damned good work at Ford. He was one of their wiz kids. He sure crapped the bed with Vietnam though.
I don't think he was in any way trying to be an apologist for RSM, but it kind of seems that way if its his only movie you've seen. For example, Morris is a Jew who once dedicated an entire movie to a hero of the Holocaust denier movement, Fred Leuchter (Titled Mr. Death: The Rise and Fall of Fred A. Leuchter, Jr., its an amazing film, also). The style is the same (as it is with most of his movies); let the guy talk, and let the audience decide what the real meaning of his words are.
Unfortunately, we didn't learn the lesson we all thought we did. I think that's one of the reasons Morris made the movie. It was a direct finger wagging at the Iraq War.
They really don't need understand it either. It made little to no sense. Generals rationally wage irrational wars, and I think they sometimes confuse strategy with the rationale.
Has anyone seen Path to War? It's about the Lyndon Johnson Administration, and much of it concerns the Vietnam War. It has Alec Baldwin as McNamara. Good movie.
