The major problem—one of the major problems, for there are several—one of the many major problems with governing people is that of whom you get to do it; or rather of who manages to get people to let them do it to them. To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it. To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.
Douglas Adams, The Restaurant at the End of the Universe (Hitchhiker's Guide to the Galaxy, #2)
I didn't mean that it should have been in the movie. There has to be scope, especially in movies. But it is important to learn about these things. Oppenheimer just gives an opportunity to revisit these untold stories. It was the article itself that brought up the link between the marbles indicating how much refined (I believe it was actually enriched but the article just talked about refined ore) and what was going on in the Congo behind the scenes. For every great man/woman/story, there are thousands of others that prop them up for greatness, often being forced to do so.
So my intent in posting was not a criticism of the movie, but simply to share this story that I had just learned.
