Nope you are wrong Bro. Imperial Japan and Nazi Germany could have technically won the war if not for their own leaders foolish/wrong decisions they took few years later after they were winning the war and bad luck. For one Hitler made the mistake of not focusing on defeating/invading Britain first before having any thoughts if invading Russia. Second the German invasion of soviet union was done at the wrong time (something Hitler's own generals like Goering were against at that period of time). Contrary to what many think, soviet union was farrrrt inferior to Nazi Germany in all fields(similar to China vs imperial Japan), the only saving grace that save Russia from total invasion/defeat was .......yes the Russian winter, which bugged down/slowed the Nazis from taking Moscow. If not for this Russia would have obviously fallen(it came very close to it). Furthermore
Furthermore, Japan also made a huge blunder when deciding to invade China(similar to Germany's foolish decision to invade Russia) which made them lose previous resources/manpower and suffer huge casualties (50% of their cssualties during the war was against the KMT china) for no real gain which also bogged them down. Japan could have just be contented with ruling all the Asian countries it had already invaded/controlled.It should have also cone into an understanding with great powers like the U.S to not touch the Philippines and share the Asian bounty with western powers.Instead it foolishly attacked the U.S itself(whom until then was neutral/didn't want to enter the war). By then it was doomed.
So in short, Nazi Germany and Japan could have technically won the war. It was possible if they had made some rational decisions or better still if I was their policy maker.
