What do you think would have happened if the Axis Powers won World War II?
I think if the Axis Powers won World War II, there would be a power struggle between the victors, just as what happened in our reality. I think the difference would be that Nazi Germany and the Empire of Japan would be fighting a more "active" war than the Cold War that happened between NATO and the Warsaw Pact. There would be more direct fighting between the two as they try to conquer the world.
Also, territory would be more tightly controlled by the two world powers. The world would have been polarized much more than if the Allies were the victors.
I think Japan would slowly progress to a quasi-constitutional monarchy in the Prussian sense - the Emperor would still retain a lot of power but the Imperial Diet and the Prime Minister would serve as an effective legislature too. Voting rights would only be limited to Japanese Males over 18 or something. Their territory would make up most of Asia and the Americas.
I think Germany would be a totalitarian empire with no human rights whatsoever (except for certain "Aryan" people.) The Fuhrer Adolf Hitler would be the supreme leader, as well as his descendants or appointed successors. Their territory would be all of Europe, Africa, and some of Asia and the Americas.
There may still be some rebel groups in far reaches of the world who would want to restore freedoms before World War II...but they would have to work covertly.
