Hitler intended to blame the Jews for the new world war he was soon to provoke. That war began in September 1939 as German troops stormed into Poland, a country that was home to over three million Jews. After Poland's quick defeat, Polish Jews were rounded up and forced into newly established ghettos at Lodz, Krakow, and Warsaw, to await future plans. Inside these overcrowded walled-in ghettos, tens of thousands died a slow death from hunger and disease amid squalid living conditions. The ghettos soon came under the jurisdiction of Heinrich Himmler, leader of the Nazi SS, Hitler's most trusted and loyal organization, composed of fanatical young men considered racially pure according to Nazi standards.
It may be, though, that a new production, even now, and even with cautious additions, will be heard in the play’s original voice. It was always a voice of good will; it meant, as we say, well—and, financially, it certainly did well. But it was Broadway’s style of good will, and that, at least for Meyer Levin, had the scent of ill. For him, and signally for Bloomgarden and Kanin, the most sensitive point—the focus of trouble—lay in the ancient dispute between the particular and the universal. All that was a distraction from the heart of the matter: in a drama about hiding, evil was hidden. And if the play remains essentially as the Hacketts wrote it, the likelihood is that Anne Frank’s real history will hardly prevail over what was experienced, forty years ago, as history transcended, ennobled, rarefied. The first hint is already in the air, puffed by the play’s young lead: It’s funny, it’s hopeful, and she’s a happy person.
 In October 1942, Jan Karski met clandestinely with Jewish leaders at the height of the destruction of Polish Jewry. As a courier for the underground, he delivered their dire message to the Polish government-in-exile in London. “The Jews were abandoned by governments, by church hierarchies, by existing societal structures. But they were not abandoned by all of humanity,” said Karski. “There were thousands upon thousands of people in Europe who risked their life for the Jews. They were priests, nuns, workers, peasants, enlightened ones, simpletons, from all walks of life. They were good people, very simply. We have more good people than probably we think we have in humanity.” Karski was recognized by Yad Vashem as a Righteous Gentile among the Gentiles on June 2, 1982
After WWII had ended, photographs of the Holocaust stunned the public. Newspapers in the United States had reported on the oppression of the Jews in Germany during the war. In 1942, many newspapers were writing details of the Holocaust, but these stories were short and were not widely read. In 1943, after sources had confirmed the killings of at least two million Jews in concentration camps across Europe a Gallup poll found that less than half of Americans believed these reports to be true; 28% thought they were “just a rumor”. The reports were unconfirmed and sometimes denied by the United States government.

Before World War II, Germany considered mass deportation from Europe of German, and later European, Jewry.[130] Among the areas considered for possible resettlement were British Palestine[131] and French Madagascar.[132] After the war began, German leaders considered deporting Europe's Jews to Siberia.[133][134] Palestine was the only location to which any German relocation plan produced results, via the Haavara Agreement between the Zionist Federation of Germany and the German government.[135] This resulted in the transfer of about 60,000 German Jews and $100 million from Germany to Palestine, but it ended with the outbreak of World War II.[136] In May 1940 Madagascar became the focus of new deportation efforts[132] because it had unfavorable living conditions that would hasten deaths.[137] Several German leaders had discussed the idea in 1938, and Adolf Eichmann's office was ordered to carry out resettlement planning, but no evidence of planning exists until after the fall of France in June 1940.[138] But the inability to defeat Britain prevented the movement of Jews across the seas,[139] and the end of the Madagascar Plan was announced on 10 February 1942.[140]

Gentiles whose status placed them on the periphery of a community generally had fewer social constraints and a higher level of independence. This sense of independence, in turn, seems to have made many rescuers more likely to act in accordance with their personal values and moral precepts, even when these standards were in opposition to societal norms. Such rescuers were propelled by values connected to self-approval. In interviews, they insisted again and again that they had to be at peace with themselves, with their ideas of what was right or wrong.

Anne's already budding literary ambitions were galvanized on 29 March 1944 when she heard a London radio broadcast made by the exiled Dutch Minister for Education, Art, and Science, Gerrit Bolkestein,[17] calling for the preservation of "ordinary documents—a diary, letters ... simple everyday material" to create an archive for posterity as testimony to the suffering of civilians during the Nazi occupation. On May 20, 1944, she notes that she started re-drafting her diary with future readers in mind.[19] She expanded entries and standardized them by addressing all of them to Kitty, clarified situations, prepared a list of pseudonyms, and cut scenes she thought would be of little interest or too intimate for general consumption. By the time she started the second existing volume, she was writing only to Kitty.

The 15 men present at Wannsee included Adolf Eichmann (head of Jewish affairs for the RSHA and the man who organized the deportation of Jews), Heinrich Müller (head of the Gestapo), and other party leaders and department heads.[256] Thirty copies of the minutes were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder.[263] Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony.[264] The conference had several purposes. Discussing plans for a "final solution to the Jewish question" ("Endlösung der Judenfrage"), and a "final solution to the Jewish question in Europe" ("Endlösung der europäischen Judenfrage"),[256] it was intended to share information and responsibility, coordinate efforts and policies ("Parallelisierung der Linienführung"), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German Mischlinge (half-Jews).[265] Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance."[256] He continued:
Most Holocaust historians define the Holocaust as the enactment, between 1941 and 1945, of the German state policy to exterminate the European Jews.[a] In Teaching the Holocaust (2015), Michael Gray, a specialist in Holocaust education,[27] offers three definitions: (a) "the persecution and murder of Jews by the Nazis and their collaborators between 1933 and 1945", which views the events of Kristallnacht in Germany in 1938 as an early phase of the Holocaust; (b) "the systematic mass murder of the Jews by the Nazi regime and its collaborators between 1941 and 1945", which acknowledges the shift in German policy in 1941 toward the extermination of the Jewish people in Europe; and (c) "the persecution and murder of various groups by the Nazi regime and its collaborators between 1933 and 1945", which includes all the Nazis' victims. The third definition fails, Gray writes, to acknowledge that only the Jewish people were singled out for annihilation.[28]
Folman and Polonsky’s greatest missed opportunity, however, is their representation of Anne. As readers have been aware since the Definitive Edition appeared more than 20 years ago, the “Diary” as we know it, despite its misleading title, isn’t a literal diary. In spring 1944, the inhabitants of the Annex heard a radio broadcast in which a Dutch cabinet minister called for citizens to preserve their diaries and letters as a record of the war years — a moment depicted in the graphic adaptation. Afterward, Anne began to revise what she had written for eventual publication as an autobiographical novel, working at the furious rate of up to a dozen pages a day. She rewrote and standardized early entries and also created new ones to fill in gaps in her story, such as the history of her family. What we have come to think of as Anne’s diary, as Francine Prose and others have written, would be more accurately described as a memoir in the form of diary entries. But myths die slow deaths, and most readers still aren’t aware of the complexities behind the book’s creation.
In response to a typhus epidemic in the women's camp, Mengele cleared one block of six hundred Jewish women and sent them to their deaths in the gas chambers. The building was then cleaned and disinfected, and the occupants of a neighboring block were bathed, de-loused, and given new clothing before being moved into the clean block. This process was repeated until all of the barracks were disinfected. Similar procedures were used for later epidemics of scarlet fever and other diseases, with infected prisoners being killed in the gas chambers. For these actions, Mengele was awarded the War Merit Cross (Second Class with swords) and was promoted in 1944 to First Physician of the Birkenau subcamp.[37]
Methods of mass murder evolved at local levels as well as being decreed from Nazi high command. Killing squads rounded up and shot entire Jewish communities. Over two days in Kiev, 33,771 Jews were shot. The murder of Jews rapidly escalated, in part because local Nazi leaders didn’t have enough room to place them in the ghettos. By the end of the year, plans to implement the systematic slaughter of Jews by using gas in mobile trucks and gas chambers were well underway.
The entry of the U.S. into the War is also crucial to the time-frame proposed by Christian Gerlach, who argued in his 1997 thesis,[122] that the Final Solution decision was announced on 12 December 1941, when Hitler addressed a meeting of the Nazi Party (the Reichsleiter) and of regional party leaders (the Gauleiter).[123][a] The day after Hitler's speech, on 13 December 1941 Joseph Goebbels wrote in his diary:[125]

Mengele then moved to experimentation. His work revolved around genetic engineering to eradicate inferior genes from the human population to create a German super-race. He believed that twins held these mysteries, and about 1500 pairs of them were brought to Mengele through the selection process. The twins were provided more comfort than the other prisoners and given extra food rations to keep them healthy. As soon as a pair of twins arrived at Auschwitz, they were tattooed and Mengele would ask them questions about their history. Every morning, they reported for roll call, where they ate a small breakfast. Mengele would then come to talk to them, give them candy, and even play games with some of them. Some of the younger children even called him “Uncle Mengele.” Life wasn’t so bad for twins at the barracks, until it came time for the experiments.

A unique example of anti-Nazi resistance occurred in the Bialystok ghetto, where several anti-Nazi German and Austrian soldiers were sentenced to death for smuggling weapons and wireless sets to the Jewish resistance. One of these men, Otto Busse, survived and settled in the Kibbutz Nes Amin in 1969, devoting his life to Israel as a concrete example of “Christian atonement.”
Theodor Holman wrote in reply to Sietse van der Hoek that the diary entry for 28 September 1942 proved conclusively the character's fictional origin.[citation needed] Jacqueline van Maarsen agreed,[citation needed] but Otto Frank assumed his daughter had her real acquaintance in mind when she wrote to someone of the same name.[citation needed] However, Kitty Egyedi said in an interview that she was flattered by the assumption, but doubted the diary was addressed to her:

While the labour camps at Auschwitz and Majdanek used inmates for slave labour to support the German war effort, the extermination camps at Belzec, Treblinka, and Sobibor had one task alone: killing. At Treblinka a staff of 120, of whom only 30 were SS (the Nazi paramilitary corps), killed some 750,000 to 925,000 Jews during the camp’s 17 months of operation. At Belzec German records detail a staff of 104, including about 20 SS, who killed some 500,000 Jews in less than 10 months. At Sobibor they murdered between 200,000 and 250,000. These camps began operation during the spring and summer of 1942, when the ghettos of German-occupied Poland were filled with Jews. Once they had completed their missions—murder by gassing, or “resettlement in the east,” to use the language of the Wannsee protocols—the Nazis closed the camps. There were six extermination camps, all in German-occupied Poland, among the thousands of concentration and slave-labour camps throughout German-occupied Europe.
This past fall, I reached out to Hana Amir, Zeidel’s daughter, and we spoke several times over Skype. From her home in Tel Aviv, Amir, who is slight and spectacled, with a gray bob, told me about how she learned of her father’s story. When Amir was young, Zeidel worked as a truck driver, and he was gone for long stretches at a time. At home, he was withholding with his daughter and two sons. “My father was of a generation that didn’t talk about their emotions, didn’t talk about how they felt about what they’d been through,” Amir told me. “This was their coping mechanism: If you’re so busy with moving forward, you can disconnect from your memories.” But there were signs that the past wasn’t done with Zeidel: Amir believes he suffered from recurrent nightmares, and he was fastidious about his personal hygiene—he washed his hands many times a day.
Hitler also believed the very presence of Jews in Germany and Nazi-occupied Europe posed a threat to German victory in the war. This was based on his experience during the First World War, when Germany had experienced a meltdown of civilian morale. In 1916, as a young soldier on sick leave in Munich, Hitler had been appalled at the apathy and anti-war sentiment he witnessed among German civilians. At the time, he concluded disloyal Jews had banded together and conspired to undermine the German war effort. And he was convinced they would do it again now if given the chance.
In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross 2nd Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with von Verschuer, who was now director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.[20][21][22]
