I've seen some of it now (before it jammed up on my computer).
I used to think that the world was the way it is because of a conspiracy the politicians were all in cahoots about.
But people do disagree. They take all kinds of crazy positions and opinions. And they get together to promote what they believe. It only looks like a conspiracy when you disagree with them.
Politicians of the same era in the same country who deal with the same issues and problems and institutions (and the same contributors) are bound to look more similar than different if you look at them from far enough away.
So I doubt it's all Cecil Rhodes's fault. The man loved the British Empire. And now it's gone. If the conspiracy were that effective, how did Rhodesia become Zimbabwe or Mugabia or whatever it is today?
