On the Recurrence of Genocide
Hannah Arendt:
Whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been. The particular reasons that speak for the possibility of a repetition of the crimes committed by the Nazis are even more plausible. The frightening coincidence of the modern population explosion with the discovery of technical devices that, through automation, will make large sections of the population “superfluous” even in terms of labor, and that, through nuclear energy, make it possible to deal with this twofold threat by the use of instruments beside which Hitler’s gassing installations look like an evil child’s fumbling toys, should be enough to make us tremble.
