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]
The number of Afro-Germans in Germany when the Nazis came to power is variously estimated at 5,000–25,000.[454] It is not clear whether these figures included Asians. Although blacks, including prisoners of war, in Germany and German-occupied Europe were subjected to incarceration, sterilization, murder, and other abuse, there was no programme to kill them all as there was for the Jews.[455]
Jewish refugees were the subject of two international conferences, at Evian in 1938 and Bermuda in 1943. Neither conference resulted in any concrete action. In general, Britain treated refugees from Nazi Germany as economic migrants, and took in only those who would be of economic benefit to the country. About 10,000 Jewish children were brought to Britain in 1939 under the Kindertransport scheme, and placed with British families, but their parents were excluded and had to pay for their children's support. The best that can be said for Britain's refugee policy is that it was less ungenerous than that of most other European states at the time.
As reported in The New York Times in 2015, "When Otto Frank first published his daughter's red-checked diary and notebooks, he wrote a prologue assuring readers that the book mostly contained her words".[53] Although many Holocaust deniers, such as Robert Faurisson, have claimed that Anne Frank's diary was fabricated,[54][55] critical and forensic studies of the text and the original manuscript have supported its authenticity.[56]

Zeidel had spent the previous two years in German-occupied Vilnius, in the city’s walled-off Jewish ghetto. He’d watched as the Nazis sent first hundreds and then thousands of Jews by train or truck or on foot to a camp in the forest. A small number of people managed to flee the camp, and they returned with tales of what they’d seen: rows of men and women machine-gunned down at close range. Mothers pleading for the lives of their children. Deep earthen pits piled high with corpses. And a name: Ponar.

A subsidiary aim of Operation Reinhard was to exploit a small minority of Jews residing in the Generalgouvernement as forced laborers before killing them. As the ghettos in Poland were systematically liquidated, those selected to live temporarily were deported to Operation Reinhard labor camps and to the concentration camp Lublin/Majdanek. This camp was established in 1941 under the authority of the Inspectorate of Concentration Camps in Berlin. Though conceived of and functioning in practice primarily as a concentration camp, housing political prisoners and Jewish forced laborers, Majdanek served from time to time as a killing site for Jews residing in the Generalgouvernement. It had gas chambers, in which the SS killed tens of thousands of Jews, primarily forced laborers too weak to work.
^ Goebbels noted: "Regarding the Jewish question, the Fuhrer is determined to clear the table. He warned the Jews that if they were to cause another world war, it would lead to their own destruction. Those were not empty words. Now the world war has come. The destruction of the Jews must be its necessary consequence. We cannot be sentimental about it. It is not for us to feel sympathy for the Jews. We should have sympathy rather with our own German people. If the German people have to sacrifice 160,000 victims in yet another campaign in the east, then those responsible for this bloody conflict will have to pay for it with their lives."[262]
Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]
Otto Frank grew up with a social need to please his environment and not to offend it; that was the condition of entering the mainstream, a bargain German Jews negotiated with themselves. It was more dignified, and safer, to praise than to blame. Far better, then, in facing the larger postwar world that the diary had opened to him, to speak of goodness rather than destruction: so much of that larger world had participated in the urge to rage. (The diary notes how Dutch anti-Semitism, “to our great sorrow and dismay,” was increasing even as the Jews were being hauled away.) After the liberation of the camps, the heaps of emaciated corpses were accusation enough. Postwar sensibility hastened to migrate elsewhere, away from the cruel and the culpable. It was a tone and a mood that affected the diary’s reception; it was a mood and a tone that, with cautious yet crucial excisions, the diary itself could be made to support. And so the diarist’s dread came to be described as hope, her terror as courage, her prayers of despair as inspiring. And since the diary was now defined as a Holocaust document, the perception of the cataclysm itself was being subtly accommodated to expressions like “man’s inhumanity to man,” diluting and befogging specific historical events and their motives. “We must not flog the past,” Frank insisted in 1969. His concrete response to the past was the establishment, in 1957, of the Anne Frank Foundation and its offshoot the International Youth Center, situated in the Amsterdam house where the diary was composed, to foster “as many contacts as possible between young people of different nationalities, races and religions”—a civilized and tenderhearted goal that nevertheless washed away into do-gooder abstraction the explicit urge to rage that had devoured his daughter.
The foundation also relies on the fact that another editor, Mirjam Pressler, had revised the text and added 25 percent more material drawn from the diary for a "definitive edition" in 1991, and Pressler was still alive in 2015, thus creating another long-lasting new copyright.[53] The move was seen as an attempt to extend the copyright term. Attard had criticised this action only as a "question of money",[58] and Ertzscheid concurred, stating, "It [the diary] belongs to everyone. And it is up to each to measure its importance."[59]

Following the invasion of Poland, German occupation policy especially targeted the Jews but also brutalized non-Jewish Poles. In pursuit of lebensraum, Germany sought systematically to destroy Polish society and nationhood. The Nazis killed Polish priests and politicians, decimated the Polish leadership, and kidnapped the children of the Polish elite, who were raised as “voluntary Aryans” by their new German “parents.” Many Poles were also forced to perform hard labour on survival diets, were deprived of property and uprooted, and were interned in concentration camps.

The Final Solution was a plan of Adolf Hitler's to kill all the Jews in Europe. Hitler's Anti- Semitic ideas were so strong that he released hatred by mass murder. Before Hitler decided to become dictator the Final Solution was already in his head. In a couple of books written by Gerald Fleming Hitler says '' Once I  am really in power my first task will be the genocide of the Jews .'' He achieved his goal by killing six million Jews. Hitler began  the final solution in every European Nation he was  control of. The Jews were sent to concentration/death camps.
In 1942, Auschwitz II (Birkenau), originally intended to house slave laborers, began to be used instead as a combined labor camp and extermination camp.[23][24] Prisoners were transported there by rail from all over German-occupied Europe, arriving in daily convoys.[25] By July 1942, SS doctors were conducting "selections" where incoming Jews were segregated, and those considered able to work were admitted into the camp while those deemed unfit for labor were immediately killed in the gas chambers.[26] The arrivals that were selected to die, about three-quarters of the total,[a] included almost all children, women with small children, pregnant women, all the elderly, and all of those who appeared (in a brief and superficial inspection by an SS doctor) to be not completely fit and healthy.[28][29]
