A "what if" question about the repercussions on this subject, what does happen when almost all the European Jews have been killed under Nazi Germany? Especially on the topics mentioned below:
Zionism. Legitimised in a gradual sense towards the Orthodox Jewish populations since the 1920s, what happens when there are so few Orthodox Jews left? There were only a few Jews living in the British Palestinian Mandate-- not enough to form the nation of Israel or some other Jewish state. Would there even be Jewish state? Would the legitimacy of zionism be able to uphold with the collapse of most of the Orthodox Jewish population? What happens to the Palestinian Mandate? Would it just be a mixed-ethnic state of Palestine once the war is over as what few remaining zionist orthodox jews be able to compromise with the Arab Palestinians? Or would the remaining Palestinian Jews just be absorbed into the majority-Arab government as a minority population? Or would it be more conflicts and incidents as the mandate moves towards independence? What does happen to the mandate once it gains independence?
Post-war Germany. Specifically the culture when the post-war Germany is denazified. During denazification, what happens to future German conditionings and mindsets when the Nazis have wiped out nearly all of the European Jewish populations? After being conditioned about the subject, would the mindset of what happened during Nazi-German regime have such a profound impact in the identity of being German or something along those lines? What would the culture, mindset, and identity of ordinary Germans after the war be like? What would ordinary Germans feel towards the subject once learning about it after denazification? And how far would denazification go between the West and East Germanies, and later, when united?
The Western/global perception of Judaism and genocide. Would there be a much more daunting effort to prevent further genocide? What is the global perception of Jews and Judaism be like after a much more thorough genocide by the Nazis in occupied Europe? What would the global response to future and past genocides be like? Would the Armenian genocide from Turkey be brought up more and cause a much wider controversy amongst Western circles?
Nazi Germany and Neo-Nazi Portrayal. After achieving such a feat, what would the Western impression of Nazi Germany, neo-nazism, and fascism be like afterwards? Would it be the same as OTL or would the perception and responses to Nazi Germany portrayal and neo-nazism be more assertively negative? What is the general perception of fascism be like? More responsive and assertive or passive?
