"The killing sites that most closely fit such a framework were the German prisoner-of-war camps. They were the only type of facility (German or Soviet) where the purpose of concentrating human beings was to kill them. Soviet prisoners of war, crushed together in the tens of thousands and denied food and medical care, died quickly and in great numbers: some three million perished, most of them in a few months. Yet this major example of killing by concentration had little to do with Arendt’s concept of modern society. Her analysis directs our attention to Berlin and Moscow, as the capitals of distinct states that exemplify the totalitarian system, each of them acting upon their own citizens. Yet the Soviet prisoners of war died as a result of the interaction of the two systems. Arendt’s account of totalitarianism centers on the dehumanization within modern mass industrial society, not on the historical overlap between German and Soviet aspirations and power. The crucial moment for these soldiers was their capture, when they passed from the control of their Soviet superior officers and the NKVD to that of the Wehrmacht and the SS. Their fate cannot be understood as progressive alienation within one modern society; it was a consequence of the belligerent encounter of two, of the criminal policies of Germany on the territory of the Soviet Union. Elsewhere, concentration was not usually a step in a killing process but rather a method for correcting minds and extracting labor from bodies. With the important exception of the German prisoner-of-war camps, neither the Germans nor the Soviets intentionally killed by concentration. Camps were more often the alternative than the prelude to execution. During the Great Terror in the Soviet Union, two verdicts were possible: death or the Gulag. The first meant a bullet in the nape of the neck. The second meant hard labor in a faraway place, in a dark mine or a freezing forest or on the open steppe; but it also usually meant life. Under German rule, the concentration camps and the death factories operated under different principles. A sentence to the concentration camp Belsen was one thing, a transport to the death factory Bełżec something else. The first meant hunger and labor, but also the likelihood of survival; the second meant immediate and certain death by asphyxiation. This, ironically, is why people remember Belsen and forget Bełżec."
