My rough ideas for this were Hitler dying around 1938, followed by a stepping down (though not a total cessation) of Nazi racial policies, coupled with increased Soviet aggression towards in the East. By 1965 or thereabouts, the world looks like this, with Britain facing off against the Soviet Union, supported by France, the E.U (dominated by Facists), and the German Reich, which is a shelter for many Eastern European countries from the Soviet menace. There has never been a Holocaust, though Jews in Nazi Germany remain second class citizens, and gyspies are reguarly expelled from the Reich. The USA is fairly isolationist, as it only began to emerge from the Depression around 1948, owing to the lack of a real Second World War to kick start manufacturing, but nevertheless dominates Central America and the Caribbean, blocking Soviet attempts at expansion here.
So, your challenge is to elaborate, pick apart my mini alt-history, and have a think about what could happen next. Enjoy!
