Hitler dies in 1938, just after Munich; Göring takes over. As a pragmatic (if corrupt) leader, he takes a dim view of the SS and other fanatics and runs Germany as a traditional dictatorship. When the Soviets attack Poland in 1942, Germany allies with the free world to defend it, defeating the Soviet armies and liberating Russia in the process. With international supervision and without the racial fanatics at the top, Germany doesn't treat the Russians as badly and are genuine liberators. After the war, a partitioned Russia of independent capitalist nations is set up; Germany regains Danzig and the Corridor. It then exists till Göring dies in the late '50s/early '60s, after which it becomes a democracy again.
The Jews in Poland are resettled to Palestine due to native and Nazi anti-Semitism.
In the Pacific, the US goes to war over Panay, never allowing the Japanese to get as far as they did IOTL. Japan negotiates a peace which leaves the Home Isles untouched while still evacuating China and giving up its Imperial ambitions.
Thus, both the worst of Nazism, Communism and Japanism are avoided. THere is still a major war, but that is more or less unavoidable.
