One thing that I think people ignore when they say, if Germany took Britain, we would have eventually won anyway. I'm not so sure. First of all, would the US have even bothered? It would have been a lot easier to make a peace with the new Nazi superstate. Also, remember, if Britain went down, you could count on Egypt going down also. Hitler would have been unchallenged in North Africa and the Middle East, once he turned his attention that way. India would also be in a very perilous position. I really think the defeat of Britain would have allowed the Nazi's a good chance of taking Russia down, at least the Ukraine. Think of the resources that would have been at Hitler's disposal!
