^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]

The capture, trial and execution in the early 1960s of Adolf Eichmann, the bureaucratic organizer of the Holocaust, led many people to believe that the Mossad would next want to get its hands on Mengele. Many in Israel and around the world figured that the Mossad would have no trouble doing so. But the truth was that for years, the leaders of the government and the agency were simply not all that interested.

This is not about people acting out a crime of passion. This is planned and rationalized violence — a cultural brainwashing. The rationalization is always that the victims are not truly human, not worthy of the same protections of the law. It’s interesting that the Nazis are often linked to Christianity, especially the Catholic Church. But it is precisely the teachings of the Church that stand in the way of such dehumanization. This is something that Mengele himself knew, as he was raised in a Catholic family. In fact, in his post-WWII journal, Mengele specifically wrote, “We had to liberate Germanic history from Roman and Catholic influences.”

Today, I am going to refer quite frankly to a very grave chapter. We can mention it now among ourselves quite openly and yet we shall never talk about it in public. I'm referring to the evacuation of the Jews, the extermination of the Jewish people. Most of you will know what it's like to see 100 corpses side by side or 500 corpses or 1,000 of them. To have coped with this and—except for cases of human weakness—to have remained decent, that has made us tough. This is an unwritten—never to be written—and yet glorious page in our history.[127]
Sophia Litwinska made a sworn affidavit that was entered into the British trial of the SS staff at Bergen-Belsen in the fall of 1945. Some members of the SS staff at Belsen had previously worked at Birkenau and they were on trial for crimes committed at both Birkenau and Belsen. One of the men who was tried by the British was Franz Hoessler, the commander of the women's camp at Birkenau in 1942; he was transferred to Bergen-Belsen in December 1944.
Nolte's views were widely denounced. The debate between the "specifists" and "universalists" was acrimonious; the former feared debasement of the Holocaust and the latter considered it immoral to hold the Holocaust as beyond compare.[478] In her book Denying the Holocaust (1993), Deborah Lipstadt viewed Nolte's position as a form of Holocaust denial, or at least "the same triumph of ideology over truth".[479] Addressing Nolte's argument, Eberhard Jäckel wrote in Die Zeit in September 1986 that "never before had a state, with the authority of its leader, decided and announced that a specific group of humans, including the elderly, women, children and infants, would be killed as quickly as possible, then carried out this resolution using every possible means of state power".[h] Despite the criticism of Nolte, Dan Stone wrote in 2010 that the Historikerstreit put "the question of comparison" on the agenda.[480] He argued that the idea of the Holocaust as unique has been overtaken by attempts to place it within the context of early-20th-century Stalinism, ethnic cleansing, and the Nazis' intentions for post-war "demographic reordering", particularly the Generalplan Ost, the plan to kill tens of millions of Slavs to create living space for Germans.[481] The specifist position continued nevertheless to inform the views of many specialists. Richard J. Evans argued in 2015:
But Auschwitz-Birkenau became more than a concentration camp. In the spring of 1942 gas chambers were built at Birkenau and mass transports of Jews began to arrive. Some of the new arrivals were inducted into the camp as registered prisoners, but the great majority were gassed immediately. These gassing operations were greatly expanded in the spring of 1943 with the construction of four purpose-built gas chamber and crematorium complexes, which included such refinements as electric lifts to carry bodies up to the crematoria. Each crematorium could handle 2,000 victims daily. In a nearby group of barracks, nicknamed 'Canada' by the prisoners, victims' belongings were sorted for transportation to the Reich. The victims' hair was used to stuff mattresses; gold teeth were melted down and the gold deposited to an SS account.
In his 1983 book, Popular Opinion and Political Dissent in the Third Reich, Ian Kershaw examined the Alltagsgeschichte (history of everyday life) in Bavaria during the Nazi period. The most common viewpoint of Bavarians was indifference towards what was happening to the Jews, he wrote. Most Bavarians were vaguely aware of the genocide, but they were vastly more concerned about the war.[472] Kershaw argued that "the road to Auschwitz was built by hate, but paved with indifference".[473] His assessment faced criticism from historians Otto Dov Kulka and Michael Kater. Kater maintained that Kershaw had downplayed the extent of popular antisemitism. Although most of the "spontaneous" antisemitic actions of Nazi Germany had been staged, Kater argued that these had involved substantial numbers of Germans, and therefore it was wrong to view the extreme antisemitism of the Nazis as coming solely from above.[474] Kulka argued that "passive complicity" would be a better term than "indifference".[475] Focusing on the views of Germans opposed to the Nazi regime, the German historian Christof Dipper, in his essay "Der Deutsche Widerstand und die Juden" (1983), argued that the majority of the anti-Nazi national-conservatives were antisemitic. No one in the German resistance supported the Holocaust, but Dipper wrote that the national conservatives did not intend to restore civil rights to the Jews after the planned overthrow of Hitler.[474]
Throughout German-occupied territory the situation of the Jews was desperate. They had meagre resources and few allies and faced impossible choices. A few people came to their rescue, often at the risk of their own lives. Swedish diplomat Raoul Wallenberg arrived in Budapest on July 9, 1944, in an effort to save Hungary’s sole remaining Jewish community. Over the next six months, he worked with other neutral diplomats, the Vatican, and Jews themselves to prevent the deportation of these last Jews. Elsewhere, Le Chambon-sur-Lignon, a French Huguenot village, became a haven for 5,000 Jews. In German-occupied Poland, where it was illegal to aid Jews and where such action was punishable by death, the Zegota (Council for Aid to Jews) rescued a similar number of Jewish men, women, and children. Financed by the London-based Polish government in exile and involving a wide range of clandestine political organizations, Zegota provided hiding places and financial support and forged identity documents.

Mengele fled Germany to Argentina in 1948, using false documents given to him by the Red Cross. (According to the Mossad’s file, the organization was aware that it was helping a Nazi criminal escape justice.) In Buenos Aires, he lived at first under an assumed name, but later reverted to his own name. He even had a nameplate on his door: Dr. Josef Mengele.
Despite the overwhelming odds, individual rescues sometimes succeeded, especially if the Jewish fugitives could pass as natives in language, manner, and appearance; if the hideout was skillfully camouflouged; if the local population was sympathetic; if geography and distance from neighboring homes aided concealment; and if organized groups or sympathetic friends provided additional safe houses and forged ration papers for essentials like food and clothing.
In early 1943, encouraged by von Verschuer, Mengele applied to transfer to the concentration camp service.[20][30] His application was accepted and he was posted to Auschwitz, where he was appointed by SS-Standortarzt Eduard Wirths, chief medical officer at Auschwitz, to the position of chief physician of the Zigeunerfamilienlager (Romani family camp) at Birkenau,[20][30] a subcamp located on the main Auschwitz complex. The SS doctors did not administer treatment to the Auschwitz inmates, but supervised the activities of inmate doctors who had been forced to work in the camp medical service.[31] As part of his duties, Mengele made weekly visits to the hospital barracks and ordered any prisoners who had not recovered after two weeks in bed to be sent to the gas chambers.[32]
