So, following up on the two previous posts, we the readers also have to work harder at the questions. Here is a background article by Barlow on Cheney.
With the possible exception of Bill Gates, Dick Cheney is the smartest man I've ever met. If you get into a dispute with him, he will take you on a devastatingly brief tour of all the weak points in your argument. But he is a careful listener and not at all the ideologue he appears at this distance. I believe he is personally indifferent to greed. In the final analysis, this may simply be about oil, but I doubt that Dick sees it that way. I am relatively certain that he is acting in the service of principles to which he has devoted megawatts of a kind of thought that is unimpeded by sentiment or other emotional overhead.
Here is the problem I think Dick Cheney is trying to address at the moment: How does one assure global stability in a world where there is only one strong power? This is a question that his opposition, myself included, has not asked out loud. It's not an easy question to answer, but neither is it a question to ignore.
