Thank you to both Tom and Susan. These are quite helpful.
One thing that struck me as I started reading Robert's book is how similar Napoleon was as a child to both Hitler and Churchill. All three were socially awkward. All three were voracious readers who seemed to prefer books to people. All three had a sense of haughtiness and self-importance and all of them felt that they were destined for greater things in life. In reading William Manchester's fantastic biography of Churchill I've been struck by how much of a warmonger Churchill was. I greatly admire the man but the jump from playing with toy soldiers to his open defiance of Hitler wasn't a great stretch to my mind. He seemed to be always fixing for a fight and relished the life and honor of being a soldier.
