America by all intents and purposes is built like a fortress, the Nazi trying to do a land invasion of America would be close to impossible. The country is surrounded by 2 separate oceans and ive you invade via the west coast you would have to then trudge through mountains and a giant desert filled with nothing, if you invade via east coast you have to deal with more mountains. Not to mention that weather can be a factor depending on when you invade you will have to contend with snowstorms, tornadoes, hurricanes, dust storms or extreme heat. America also has enough resources to manufacture weapons and equipment by itself. At best if we lived in a future were the Nazis won, we probably would still have fought the Japanese for a few more years before ultimately signing a cease fire agreement. This is not me defend ing the Nazis by the way Im just showing how this dumbass misconception is a dumbass misconception
