Half a year later, Harel was replaced by Meir Amit, who ordered the Mossad to “stop chasing after ghosts from the past and devote all our manpower and resources to threats against the security of the state.” He mandated that the agency deal with Nazis “only to the extent it is able to do so, in addition to its principal missions” and as long as “it doesn’t impinge on the other operations.”

The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger.[242] The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals.[243] By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people.[244] The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev,[245] where 33,771 Jews were killed in a single operation on 29–30 September 1941.[246][n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings.[248] Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot.[249] By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.[250]
By then, Palestinian terrorism had become Israel’s main security challenge, and the Mossad devoted most of its efforts to that threat. For the next 10 years, backed by Eshkol and his successors as prime minister, Golda Meir and Yitzhak Rabin, almost nothing was done about Mengele. The surge in terrorism, the surprise Yom Kippur War in 1973 and the Syrian military buildup with Soviet assistance took precedence.
I was miserable being me. . . . I was on the brink of that awful abyss of teenagedom and I, too, needed someone to talk to. . . . (Ironically, Anne, too, expressed a longing for more attention from her father.) . . . Dad’s whole life was a series of meetings. At home, he was too tired or too frustrated to unload on. I had something else in common with Anne. We both had to share with sisters who were prettier and smarter than we felt we were. . . . Despite the monumental differences in our situations, to this day I feel that Anne helped me get through the teens with a sense of inner focus. She spoke for me. She was strong for me. She had so much hope when I was ready to call it quits.

In October 1941 the Nazis began turning the concentration camp at Majdanek into a death camp as well. They then began the construction of killing centres at Bełżec, Treblinka, near Warsaw, and at Sobibór. The first mass gassing of Jews began in Chelmno on 8 December 1941, when the Nazis used gas vans to murder people from the Łódź ghetto. The Nazis also ordered the expansion of the Auschwitz camp complex to increase the capacity for murder.
The following year, 1941, would be the turning point. In June, Hitler took a tremendous military gamble by invading the Soviet Union. Before the invasion he had summoned his top generals and told them the attack on Russia would be a ruthless "war of annihilation" targeting Communists and Jews and that normal rules of military conflict were to be utterly ignored.
Antisemitism, the new racist version of the old Jew-hatred, viewed the Jews as not simply a religious group but as members of a 'Semitic race', which strove to dominate its 'Aryan' rivals. Among the leading ideologues of this theory were a French aristocrat, the Comte Joseph de Gobineau, and an Englishman, Houston Stewart Chamberlain. Antisemitism proved a convenient glue for conspiracy theories - since Jews were involved in all sorts of ventures and political movements, they could be accused of manipulating all of them behind the scenes. Thus Jews were held responsible for Communism and capitalism, liberalism, socialism, moral decline, revolutions, wars, plagues and economic crises. As the Jews had once been demonised in medieval Europe, so the new antisemites (including many Christians) found new, secular ways of demonising them.
The Soviets found 7,600 inmates in Auschwitz.[385] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division;[386] 13,000 corpses lay unburied, and another 10,000 people died from typhus or malnutrition over the following weeks.[387] The BBC's war correspondent, Richard Dimbleby, described the scenes that greeted him and the British Army at Belsen, in a report so graphic the BBC declined to broadcast it for four days, and did so, on 19 April, only after Dimbleby had threatened to resign.[388]
There were setbacks. In March, the diggers discovered they were tunneling in the direction of a burial pit and were forced to reroute the passageway, losing days in the process. Not long afterward, Dogim was on burial pit duty when he unearthed the bodies of his wife, mother and two sisters. Every member of the Burning Brigade lived with the knowledge that some of the corpses he was helping to burn belonged to family members. And yet to see one’s wife lying in the pit was something else entirely, and Dogim was consumed with sadness and fury. “[He] said he had a knife, that he was going to stab and kill the Sturmbannführer,” Farber later recalled. Farber told Dogim that he was thinking selfishly—even if he succeeded, the rest of the prisoners would be killed in retribution.
Majdanek, set up in September 1941 as a camp for Soviet prisoners‑of‑war and as a concentration camp for Polish Jews and non‑Jews, became the base for the SS advancing in the East and a reservoir of slave labor for factories in the Lublin region. Extermination installations were built there in the autumn of 1942, but it was only in the winter of the following year that the Zyklon B gas chambers and the crematorium were used­ for the first time. Of the 200,000 persons killed in Majdanek, about 50,000‑60,000 were Jews.
The capture and trial of Eichmann — and his execution — were enough to teach the world about the Holocaust and to convey the message that Jewish blood cannot be spilled with impunity. From that point on, it would have been better if the Mossad had let the past go. Nazis no longer posed a threat. And there is no lack of present-day enemies who did and apparently always will.
Trainloads of human cargo arriving at Auschwitz went through a selection process conducted by SS doctors such as Josef Mengele. Young adults considered fit for slave labor were allowed to live and had an ID number tattooed on their left forearm. Everyone else went to the gas chambers. A few inmates, including twin children, were occasionally set aside for participation in human medical experiments.
"For the survivor who chooses to testify, it is clear: his duty is to bear witness for the dead and the living. He has no right to deprive future generations of a past that belongs to our collective memory. To forget would be not only dangerous but offensive; to forget the dead would be akin to killing them a second time. The witness has forced himself to testify. For the youth of today, for the children who will be born tomorrow. He does not want his past to become their future." Elie Wiesel, Night, Preface to the New Translation (New York: Hill and Wang, c2006), page xv.

“I am marshalling my last remaining strength in order to die peacefully as one who will not surrender and who will not ask for forgiveness. The historical fact that Israel became the leading social political superpower in the 19th century lies before us. We have amongst us a flexible, tenacious, intelligent foreign tribe that knows how to bring abstract reality into play in many different ways. Not individual Jews but the Jewish spirit and Jewish consciousness have overpowered the world. All this is the consequence of a cultural history so unique in its way, so grand that every day polemic can achieve nothing against it. With the entire force of its armies the proud Roman Empire did not achieve that which Semitism has achieved in the West and particularly in Germany.”
Responding to domestic pressures to act on behalf of Jewish refugees, U.S. Pres. Franklin D. Roosevelt convened, but did not attend, the Évian Conference on resettlement, in Évian-les-Bains, France, in July 1938. In his invitation to government leaders, Roosevelt specified that they would not have to change laws or spend government funds; only philanthropic funds would be used for resettlement. Britain was assured that Palestine would not be on the agenda. The result was that little was attempted and less accomplished.
According to psychologist Eva Fogelman “Rescuers’ families nourished an independence of mind and spirit. … In talking with rescuers from all kinds of different homes, I found that one quality above all others was emphasized time and again: a familial acceptance of people who were different. This value was the centrepiece of the childhood of rescuers and became the core from which their rescuer self evolved. From the earliest ages, rescuers were taught by their parents that people are inextricably linked to one another. No one person or group was better than any other. The conviction that all people, no matter how marginal, are of equal value was conveyed to children of both religious and nonreligious households.” Fogelman is the daughter of a Holocaust survivor and founder of the Jewish Foundation for Christian Rescuers.
Otto Frank, it turns out, is complicit in this shallowly upbeat view. Again and again, in every conceivable context, he had it as his aim to emphasize “Anne’s idealism,” “Anne’s spirit,” almost never calling attention to how and why that idealism and spirit were smothered, and unfailingly generalizing the sources of hatred. If the child is father of the man—if childhood shapes future sensibility—then Otto Frank, despite his sufferings in Auschwitz, may have had less in common with his own daughter than he was ready to recognize. As the diary gained publication in country after country, its renown accelerating year by year, he spoke not merely about but for its author—and who, after all, would have a greater right? The surviving father stood in for the dead child, believing that his words would honestly represent hers. He was scarcely entitled to such certainty: fatherhood does not confer surrogacy.
Mengele's eye experiments included attempts to change the eye color by injecting chemicals into the eyes of living subjects, and he killed people with heterochromatic eyes so that the eyes could be removed and sent to Berlin for study.[53] His experiments on dwarfs and people with physical abnormalities included taking physical measurements, drawing blood, extracting healthy teeth, and treatment with unnecessary drugs and X-rays.[3] Many of his victims were dispatched to the gas chambers after about two weeks, and their skeletons sent to Berlin for further analysis.[54] Mengele sought out pregnant women, on whom he would perform experiments before sending them to the gas chambers.[55] Witness Vera Alexander described how he sewed two Romani twins together, back to back, in a crude attempt to create conjoined twins;[50] both children died of gangrene after several days of suffering.[56]
