As Hitler lost the World War II, US & Soviet armies saved the Jews from concentration camps and rehabilitated them in the USA & Soviet Russia.
The Allied Powers demilitarized Germany to weaken its power. The War Guilt Clause held Germany responsible for the war and damages the Allied countries suffered. Germany was forced to pay compensation amounting to £6 billion.
The Allied armies also occupied the resource-rich Rhineland for much of the 1920s. Many Germans held the new Weimar Republic responsible for not only the defeat in the war but the disgrace at Versailles.
