Though Stalin’s murder campaigns were, in many cases, predicated on ethnic antagonism, the difference is that the Soviets did not exterminate for extermination’s own sake. Once Stalin’s discrete policies had been achieved (the collectivization of Ukrainian farms, for instance), the mass murder stopped, and the Soviet Union eventually wound down its widescale deportations and mass killings in the mid- 1950s. Had Hitler’s regime, with its animalistic understanding of human nature, lasted beyond 1945, its mass murder and terror would not have decreased. For these tactics were not just means but ends; they were the very lifeblood, the weltanschauung, of nazism itself.
