In shorthand, then, the Holocaust was, in order: Operation Reinhardt, Shoah by bullets, Auschwitz; or Poland, the Soviet Union, the rest. Of the 5.7 million or so Jews killed, roughly 3 million were pre-war Polish citizens, and another 1 million or so pre-war Soviet citizens: taken together, 70 percent of the total. (After the Polish and Soviet Jews, the next-largest groups of Jews killed were Romanian, Hungarian, and Czechoslovak. If these people are considered, the East European character of the Holocaust becomes even clearer.)
