There are differences between the theories, politics and actions of Nazis and Communists that go beyond the happenstances of the twentieth century. But I wonder at how circumstances have resulted in the failure to balance their legacies in the West. We fought against the Nazis over a few years, and their atrocities were, relatively speaking, a concentrated revelation of horror. Our conflict with the Soviet Union was long and cold, and information about their horrors took longer to piece together (a process extended by leftist denial, which is alive and well today in other forms).
