I've seen some of the Island at War series. It's interesting to see the island people having to choose between self-sacrifice and survival.
I agree with AF that the war could have gone differently if Hitler had taken England. For one thing, it might have bought him time and intellectual capital for nuclear research. He already had heavy long-range bomber designs that could reach the American east coast and return.
Also, Japan could have bought time by avoiding direct conflict with America until Britain and China were fully subjegated.
One does get the sense that America had fantastic resolve and great reserves of men and materiel. I think once we had entered the war, nuclear or not, we would have fought until we had overcome the Axis, even if it had played its cards more wisely.
I wonder if we have such depth of resolve today?
I wonder if some of the Freepers that took part to this thread are - or were - fellow wargamers ?
