On July 31, 1941, Hermann Göring, writing under instructions from Hitler, ordered Reinhard Heydrich, SS general and Heinrich Himmler’s number-two man, “to submit to me as soon as possible a general plan of the administrative material and financial measures necessary for carrying out the desired final solution of the Jewish question.” Goering recounted briefly the outline for that “final solution” that had been drawn up on January 24, 1939: “emigration and evacuation in the best possible way.” This program of what would become mass, systematic extermination was to encompass “all the territories of Europe under German occupation.” Heydrich already had some experience with organizing such a plan, having reintroduced the cruel medieval concept of the ghetto in Warsaw after the German occupation of Poland. Jews were crammed into cramped walled areas of major cities and held as prisoners, as their property was confiscated and given to either local Germans or non-Jewish Polish peasants. Behind this horrendous scheme, carried out month by month, country by country, was Hitler, whose “greatest weakness was found in the vast numbers of oppressed peoples who hated [him] and the immoral ways of his government.” This assessment was Soviet dictator Joseph Stalin’s, given at a Kremlin meeting that same day, July 31, with American adviser to the president Harry Hopkins.
