Lets say that, after passing a lot of its OTL anti-Semetic legislation, Nazi Germany stops short of actually launching a genocide against the Jews (maybe Rienhard Hydrich has a car accident, maybe Hitler's generals convince him that a project like the Holocaust would suck up a lot of resources that the war effort needs, doesn't really matter what the exact POD is). Now, lets say that, in this TL, World War II follows its OTL course, but when the Nazis surrender in May 1945, Europe's Jewish population, while having endured a very rough decade, is still mostly alive.
So, how does this affect the postwar world? From my readings into Israeli history, I understand Zionism wasn't a majority opinion among Jews until the shock of Auschwitz convinced them they weren't safe in Western society-so does Israel get established in this TL? If not, what would be the effects of Poland, Belarus, and Hungary (not to mention Germany) continuing to be large centers of Jewish population and culture after the war? How would the Jewish populations of these countries react to the gradual Communist-ization after 1945, and what knock-on effects might we see on say, Polish or Hungarian culture?
Also, what effect does this have politically? I can actually see some very negative consequinces-without anti-Semetism being graphically shown for the evil it is, it might remain socially acceptable for longer

. Without the Holocaust, would the concept of "genocide" exist in political theory? If not, what would TTL's politicians and academics call things like the Yugoslav wars, Darfur, Rwanda, etc?
