British historian Burleigh (Blood Rage: A Cultural History of Terrorism) delivers a long, riveting account of the awful atrocities of WWII and the perverted reasoning behind them. Burleigh explains that Communist, Nazi, Fascist, and Japanese systems claimed to be regimes of public virtue carrying out inexorable historical processes. Proclaiming that the only evil was obstructing this march to utopia, they discarded the rule of law and alternative moral authority (religion, ethics).
