Browning also notes that the destruction of the Jews went hand-in-hand with a much wider attempt at “ethnic cleansing” throughout Eastern Europe. The Nazis had well-advanced plans, which might have been realized had they won the war, to remove by force millions of Poles and other Slavs to Siberia, with vast numbers certain to die en route. One of the major merits of Browning’s book is its detailed discussion of these plans, as well as Nazi policies towards the gypsies. Browning notes, correctly, that the Nazis killed large numbers of gypsies even though Hitler hardly ever mentioned them and certainly did not have anti-gypsy hostility at the heart of his ideology. Browning also offers a detailed consideration of the Nazi program of murdering the physically and mentally handicapped among “Aryan” Germans (the “T4 program”), which began in mid-1939 and eventually claimed seventy thousand victims before it was stopped in mid-1941, and he reports that many of the killers in the T4 program went on to be directly involved with the extermination of the Jews in Eastern Europe.

Romania implemented anti-Jewish measures in May and June 1940 as part of its efforts towards an alliance with Germany. Jews were forced from government service, pogroms were carried out, and by March 1941 all Jews had lost their jobs and had their property confiscated.[169] After Romania joined the invasion of the Soviet Union in June 1941, at least 13,266 Jews were killed in the Iași pogrom,[170] and Romanian troops carried out massacres in Romanian-controlled territory, including the Odessa massacre of 20,000 Jews in Odessa in late 1941. Romania also set up concentration camps under its control in Transnistria, where 154,000–170,000 Jews were deported from 1941 to 1943.[169]
Wallenberg was a Swedish diplomat who helped save thousands of Hungarian Jews. Wallenberg provided thousands of Jews with special Swedish passports and also set up a bureaucracy in Budapest designed to protect Jews by using "safe houses" where they could receive food and medical supplies. More than 90,000 Budapest Jews were deported to death camps; Wallenberg's efforts may have saved an equal number. Following the liberation of Budapest, Wallenberg was arrested by the Soviets and was never heard from again.
With the appointment in January 1933 of Adolf Hitler as Chancellor of Germany, and the establishment of the Third Reich, German leaders proclaimed the rebirth of the Volksgemeinschaft ("people's community").[75] Nazi policies divided the population into two groups: the Volksgenossen ("national comrades") who belonged to the Volksgemeinschaft, and the Gemeinschaftsfremde ("community aliens") who did not. Enemies were divided into three groups: the "racial" or "blood" enemies, such as the Jews and Roma; political opponents of Nazism, such as Marxists, liberals, Christians, and the "reactionaries" viewed as wayward "national comrades"; and moral opponents, such as gay men, the work shy, and habitual criminals. The latter two groups were to be sent to concentration camps for "re-education", with the aim of eventual absorption into the Volksgemeinschaft. "Racial" enemies could never belong to the Volksgemeinschaft; they were to be removed from society.[76]
Mengele sailed to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, then fled to Paraguay in 1959 and Brazil in 1960, while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal who wanted to bring him to trial. He eluded capture in spite of extradition requests by the West German government and clandestine operations by the Israeli intelligence agency Mossad. He drowned in 1979 after suffering a stroke while swimming off the Brazilian coast, and was buried under a false name. His remains were disinterred and positively identified by forensic examination in 1985.
