Slovak rabbi Michael Dov Weissmandl was the first to suggest, in May 1944, that the Allies bomb the rails leading to Auschwitz.[224] At one point British Prime Minister Winston Churchill ordered that such a plan be prepared, but he was told that precision bombing the camp to free the prisoners or disrupt the railway was not technically feasible.[225][not in citation given] In 1978, historian David Wyman published an essay in Commentary entitled "Why Auschwitz Was Never Bombed", arguing that the United States Army Air Forces had the capability to attack Auschwitz and should have done so; he expanded his arguments in his book The Abandonment of the Jews: America and the Holocaust 1941–1945 (1984). Wyman argued that, since the IG Farben plant at Auschwitz III had been bombed three times between August and December 1944 by the US Fifteenth Air Force in Italy, it would have been feasible for the other camps or railway lines to be bombed too. Bernard Wasserstein's Britain and the Jews of Europe (1979) and Martin Gilbert's Auschwitz and the Allies (1981) raised similar questions about British inaction.[226] Since the 1990s, other historians have argued that Allied bombing accuracy was not sufficient for Wyman's proposed attack, and that counterfactual history is an inherently problematic endeavor.[227]

Raphael Lemkin, a holocaust survivor who worked on the Nuremberg Trials, coined the term genocide and spent 4 years pushing for it to be added to international law. As Champetier de Ribes, the French Prosecutor at the Nuremberg Trials explained “This [was] a crime so monstrous, so undreamt of in history throughout the Christian era up to the birth of Hitlerism that the term ‘genocide’ has had to be coined to define it.” Ultimately, in 1948 The United Nations Convention on the Prevention and Punishment of Genocide was adopted, and it entered into force in 1951. The convention defined genocide in legal terms based on Lemkin’s work, and is the basis for genocide prevention efforts today.
The Allies believed that 'blitzkrieg' was dependent on new technology, such as tanks and dive-bombers  © Shocked by their experience, the Allied military observers who had survived the fall of France attributed their defeat to the completely new form of warfare pioneered by the Wehrmacht - the blitzkrieg. Blitzkrieg seemed to be based around the pervasive use of new technology. After all, during the disastrous campaign in Belgium and France, it had seemed as if German tanks and aircraft were everywhere.
Known as Kristallnacht (or "Night of Broken Glass"), the attacks were partly carried out by the SS and SA,[122] but ordinary Germans joined in; in some areas, the violence began before the SS or SA arrived.[123] Over 7,500 Jewish shops (out of 9,000) were looted and attacked, and over 1,000 synagogues damaged or destroyed. Groups of Jews were forced by the crowd to watch their synagogues burn; in Bensheim they were forced to dance around it, and in Laupheim to kneel before it.[124] At least 90 Jews died. The damage was estimated at 39 million Reichmarks.[125] Cesarani writes that "[t]he extent of the desolation stunned the population and rocked the regime."[120] Thirty-thousand Jews were sent to the Dachau, Buchenwald and Sachsenhausen concentration camps.[126] Many were released within weeks; by early 1939, 2,000 remained in the camps.[127] German Jewry was held collectively responsible for restitution of the damage; they also had to pay an "atonement tax" of over a billion Reichmarks. Insurance payments for damage to their property were confiscated by the government. A decree on 12 November 1938 barred Jews from most of the remaining occupations they had been allowed to hold.[128] Kristallnacht marked the end of any sort of public Jewish activity and culture, and Jews stepped up their efforts to leave the country.[129]
The impact of the Holocaust varied from region to region and from year to year in the 21 countries that were directly affected. Nowhere was the Holocaust more intense and sudden than in Hungary. What took place over several years in Germany occurred over 16 weeks in Hungary. Entering the war as a German ally, Hungary had persecuted its Jews but not permitted the deportation of Hungarian citizens. In 1941 foreign Jewish refugees were deported from Hungary and were shot by Germans in Kam’yanets-Podilskyy, Ukraine. After Germany invaded Hungary on March 19, 1944, the situation changed dramatically. By mid-April the Nazis had confined Jews to ghettos. On May 15, deportations began, and over the next 55 days the Nazis deported more than 437,000 Jews from Hungary to Auschwitz on 147 trains.
After becoming Chancellor of Germany (head of government) in 1933, Adolf Hitler ignored the Versailles Treaty provisions. Within the Wehrmacht (established in 1935) the command for motorised armored forces was named the Panzerwaffe in 1936. The Luftwaffe (the German air force) was officially established in February 1935, and development began on ground-attack aircraft and doctrines. Hitler strongly supported this new strategy. He read Guderian's 1937 book Achtung – Panzer! and upon observing armoured field exercises at Kummersdorf he remarked, "That is what I want – and that is what I will have."[51][52]

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]

The photo below shows the railroad siding inside the camp, called the ramp, where the Jews exited from the trains and the selection process took place. Those who were fit for work were allowed to live for a few months, until they inevitably died of disease or overwork. The others were sent immediately to one of the four gas chambers at the far end of the camp. The gas chambers in Krema II and Krema III were at the end of the main camp road, which is shown on the left in the photo below. The railroad tracks extend about a mile into the camp, all the way to the gas chambers II and III; some of the Hungarian Jews were immediately gassed without going through a selection process, even though the Nazis were desperately in need of workers for their munitions factories. This photo was taken in the early morning, looking west from the gate house tower.
Among the key revelations in Crowe’s book: Oskar Schindler did not write out a list of people to save, he didn’t break down in tears because he thought he could have saved more people, and it is unlikely he experienced a defining moment, such as seeing a girl in a red coat, that led to his decision to save the lives of his Jewish workers. Steven Spielberg’s movie Schindler’s List, while important, impressive and admirable in many ways, took creative license on these and other issues.
Dan Stone, a specialist in the historiography of the Holocaust, lists ethnic Poles, Ukrainians, Soviet prisoners of war, Jehovah's Witnesses, black Germans, and homosexuals as among the groups persecuted by the Nazis; he writes that the occupation of eastern Europe can also be viewed as genocidal. But the German attitude toward the Jews was different in kind, he argues. The Nazis regarded the Jews not as racially inferior, deviant, or enemy nationals, as they did other groups, but as a "Gegenrasse: a 'counter-race', that is to say, not really human at all". The Holocaust, for Stone, is therefore defined as the genocide of the Jews, although he argues that it cannot be "properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans".[d] Donald Niewyk and Francis Nicosia, in The Columbia Guide to the Holocaust (2000), favour a definition that focuses on the Jews, Roma, and Aktion T4 victims: "The Holocaust—that is, Nazi genocide—was the systematic, state-sponsored murder of entire groups determined by heredity. This applied to Jews, Gypsies, and the handicapped."[33]
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
