Question

350-400 words for each:

1. In what ways did the belief systems of German National Socialism and Soviet Communism differ? What difference if any did these belief systems make in practice?
2. In what ways did the belief systems of German National Socialism and Soviet Communism resemble each other? If you want to argue that they were essentially the same, how then do you account for the extraordinary hostility between them? (Remember for example that Hitler rode into power largely declaring that the German Communist Party posed a clear and imminent threat, making necessary the emergency measures by which he created the Nazi dictatorship. The Soviet regime made similar accusations against Hitlerian fascism in justifying the Great Terror of the 1930s.)
