A Germany-dominated Europe and Russia and a Japan ruled Asia. Assuming they had won, I don't think the Axis powers would have begun fighting among each other: Italy was already nothing more than an extension of Germany (albeit a much less capable one), and Japan would have had an incredibly powerful navy with aircraft carriers; the Germans would not realistically have the capability of deploying large fleets to the other side of Asia. Further, Britain would almost certainly be a problem (either as a revolutionary zone, or as one independant of German rule), and a free America would be a threat to both Japan and Germany, especially considering the oceanic divide and the fact that a conflict on U.S. soil would probably come to involve every other country in North and South America as well.
For the Japanese, maintaining control of China would have also been difficult- with its huge population, racial tensions and strict Japanese rule (the Rape of Nanking), a revolution would almost certainly develop.
I believe that Hitler demonstrated very thoroughly that his entering into treaties were good for only as they served his immediate purpose. Both the Germans and the Japanese had the intent of global domination that would have rendered their own treaties null and void as soon as one side figured it had a decisive advantage over the other.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
