Tacitus is writing about Rwanda, and trying to explain the 1994 massacres. It's a different perspective from the ones I remember in the papers when it happened. He calls Rwanda "the Prussia of Africa", and suggests that this explains the orderly fashion in which an entire section of society acquiesced in their own destruction, that they were betrayed by their own respect for authority and order. I don't know if I agree, but it's a very compelling post.
