Regarding "Nazi Germany", it's complicated: https://en.wikipedia.org/wiki/German_Reich#Divided_Germany https://en.wikipedia.org/wiki/German_Reich#Divided_Germany The Third Reich was legally the continuation of the Weimar Republic (both of which are just colloquial names, not formal identities of Germany at the time). Neither part of post-WW2 Germany was a full successor to the Third Reich until the Reunification (in which the Allies effectively ceded most of their control to what was formerly West Germany and East Germany ceased to exist). I'm not really sure under what basis "Nazi Germany" can be considered a separate legal entity from the pre-existing Weimar Republic without also considering the Weimar Republic a separate legal entity from the pre-existing German Empire of 1871.
