Excellent explanations...
I read this one years ago: http://bevinalexander.com/books/hitler-world-war-ii.htm
Not a bad book and I certainly wanted to try out the "master plan" in a game of Third Reich or something but haven't yet done so.
I'll give this video a look later tonight. I started the first 10 minutes of it and it sounded like it was going to be very interesting!
