Hitler’s understanding of the role of the Jews in the world was not warped. His was, in fact, the traditional Jewish understanding. When the Jews accepted the Torah at Mt. Sinai, they became the chosen people whose role and responsibility was to bring a God-given code of morality to the world. They were to be “the light unto the nations” in the words of prophet Isaiah.
Anti-Jewish measures were introduced in Slovakia, which would later deport its Jews to German concentration and extermination camps. Bulgaria introduced anti-Jewish measures in 1940 and 1941, including the requirement to wear a yellow star, the banning of mixed marriages, and the loss of property. Bulgaria annexed Thrace and Macedonia, and in February 1943 agreed to deport 20,000 Jews to Treblinka; all 11,000 Jews from the annexed territories were sent to their deaths, and plans were made to deport an additional 6,000–8,000 Bulgarian Jews from Sofia to meet the quota. When the plans became public, the Orthodox Church and many Bulgarians protested, and King Boris III canceled the deportation of Jews native to Bulgaria. Instead, they were expelled to the interior pending further decision. Although Hungary expelled Jews who were not citizens from its newly annexed lands in 1941, it did not deport most of its Jews until the German invasion of Hungary in March 1944. Between 15 May and 9 July 1944, 440,000 Hungarian Jews were deported to Auschwitz. In late 1944 in Budapest, nearly 80,000 Jews were killed by the Hungarian Arrow Cross battalions.
Our many Jewish friends and acquaintances are being taken away in droves. The Gestapo is treating them very roughly and transporting them in cattle cars to Westerbork. . . .The people get almost nothing to eat, much less to drink, as water is available only one hour a day, and there’s only one toilet and sink for several thousand people. Men and women sleep in the same room, and women and children often have their heads shaved. . . . If it’s that bad in Holland, what must it be like in those faraway and uncivilized places where the Germans are sending them? We assume that most of them are being murdered. The English radio says they’re being gassed.
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.
