Those who were not considered fit for work were taken immediately by truck from the Judenrampe to two make-shift gas chambers at Birkenau, which were located in two converted farm houses called "the little red house" and "the little white house." At least 75% of the Jews in each transport of 2,000 to 3,000 prisoners were deemed unfit for work and were destined for the gas chamber. The little red house, also known as Bunker 1, had a capacity of 800 people in two rooms and the little white house, called Bunker 2, had a capacity of 1,200 in four rooms.
“I’ve offered three possibilities” to the museum, Freund said. The first was to try to partially excavate one section of the tunnel and protect it with climate-controlling plexiglass walls. Alternatively, a re-creation could be built, as had been done with the recently finished facsimile of King Tutankhamun’s tomb, in the Valley of the Kings, in Egypt. The last option, Freund allowed, was a “little futuristic”: Relying on the data from the scans, a 3-D film could be created so visitors could relive the experience of the escape.

Ultimately, one must surely conclude that the unparalleled enormities carried out by the Nazis took place because the First World War destroyed Germany’s traditional elite structure, permitting, in the context of the Depression, the rise of an extremist movement at the absolute fringes of political life which would never otherwise have come to power. Almost precisely the same thing occurred, for the same reasons, in Russia with the Bolshevik revolution and the rise of Stalin to supreme power just over a decade later. In the English-speaking world, fortunately, the legacy of internalized liberalism, enhanced by the fact that its nations were victorious in the First World War and their institutions left intact, kept the traditional governing structures viable and gave radical fringe groups no opportunity to gather political power. Arguably, too, the deep wound of 1914-1918, which caused so many horrors in Europe, was not fully healed until the fall of Communism in 1990, if even then.
In France Jews under Fascist Italian occupation in the southeast fared better than the Jews of Vichy France, where collaborationist French authorities and police provided essential support to the understaffed German forces. The Jews in those parts of France under direct German occupation fared the worst. Although allied with Germany, the Italians did not participate in the Holocaust until Germany occupied northern Italy after the overthrow of Fascist leader Benito Mussolini in 1943.
Polish gentiles who rescued Jews had several obstacles to overcome. The most serious were the German laws against protecting Jews and the corresponding obligation to identify those who violated these laws. On 15 October 1941, the Nazis introduced a widely publicized law making unauthorized Jewish movement outside ghettos a crime punishable by death. The same punishment applied to gentiles who helped Jews escape. Transgressions were promptly followed by executions that were also widely publicized.
After obtaining a copy of his birth certificate through the West German embassy in 1956, Mengele was issued with an Argentine foreign residence permit under his real name. He used this document to obtain a West German passport, also using his real name, and embarked on a trip to Europe.[71][72] He met up with his son Rolf (who was told Mengele was his "Uncle Fritz")[73] and his widowed sister-in-law Martha, for a ski holiday in Switzerland; he also spent a week in his home town of Günzburg.[74][75] When he returned to Argentina in September 1956, Mengele began living under his real name. Martha and her son Karl Heinz followed about a month later, and the three began living together. Josef and Martha were married in 1958 while on holiday in Uruguay, and they bought a house in Buenos Aires.[71][76] Mengele's business interests now included part ownership of Fadro Farm, a pharmaceutical company.[74] Along with several other doctors, Mengele was questioned in 1958 on suspicion of practicing medicine without a license when a teenage girl died after an abortion, but he was released without charge. Aware that the publicity would lead to his Nazi background and wartime activities being discovered, he took an extended business trip to Paraguay and was granted citizenship there in 1959 under the name "José Mengele".[77] He returned to Buenos Aires several times to settle his business affairs and visit his family. Martha and Karl lived in a boarding house in the city until December 1960, when they returned to Germany.[78]
Hilberg's analysis of the steps that led to the destruction of European Jews revealed that it was "an administrative process carried out by bureaucrats in a network of offices spanning a continent".[108] Hilberg divides this bureaucracy into four components or hierarchies: the Nazi Party, the civil service, industry, and the Wehrmacht armed forces – but their cooperation is viewed as "so complete that we may truly speak of their fusion into a machinery of destruction".[109] For Hilberg, the key stages in the destruction process were: definition and registration of the Jews; expropriation of property; concentration into ghettoes and camps; and, finally, annihilation.[110] Hilberg gives an estimate of 5.1 million as the total number of Jews killed. He breaks this figure down into three categories: Ghettoization and general privation: over 800,000; open-air shootings: over 1,300,000; extermination camps: up to 3,000,000.[111]

One extraordinary aspect of the journey to the death camps was that the Nazis often charged Jews deported from Western Europe train fare as third class passengers under the guise that they were being "resettled in the East." The SS also made new arrivals in the death camps sign picture postcards showing the fictional location "Waldsee" which were sent to relatives back home with the printed greeting: "We are doing very well here. We have work and we are well treated. We await your arrival."
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.[16] Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.[17]
