Dr. Josef Mengele, nicknamed The Angel Of Death, and the other Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.
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.
The truth is, Alisande, these archaics are a little TOO simple; the vocabulary is too limited, and so, by consequence, descriptions suffer in the matter of variety; they run too much to level Saharas of fact, and not enough to picturesque detail; this throws about them a certain air of the monotonous; in fact the fights are all alike: a couple of people come together with great random -- random is a good word, and so is exegesis, for that matter, and so is holocaust, and de- falcation, and usufruct and a hundred others, but land

German SS and police murdered nearly 2,700,000 Jews in the killing centers either by asphyxiation with poison gas or by shooting. In its entirety, the "Final Solution" called for the murder of all European Jews by gassing, shooting, and other means. Six million Jewish men, women, and children were killed during the Holocaust—two-thirds of the Jews living in Europe before World War II.
In addition to active help, many clergymen also protested the mistreatment and deportations of Jews as violations of divine and human laws. The Catholic pastor of St. Hedwig’s Cathedral in Berlin, Bernard Lichtenburg, prayed publicly for the Jews until his arrest and death on the way to Dachau. The rescue work of priests of all Christian denominations is well-documented in postwar literature.

Meanwhile, Hitler continued his conquest of Europe, invading Belgium, Holland, Luxembourg and France, placing ever-increasing numbers of Jews under Nazi control. The Nazis then began carefully tallying up the actual figures and also required Jews to register all of their assets. But the overall question remained as to what to do with the millions of Jews now under Nazi control - referred to by the Nazis themselves as the Judenfrage (Jewish question).
The Mossad was still a young agency, short of resources and manpower. Moreover, as Aharoni later put it in testimony for the Mossad’s history department, “When Isser began dealing with something, he dealt only with that.” In addition, the agency had been blindsided, knowing nothing about the German scientists and the missiles they were building for Israel’s biggest enemy. Harel mobilized the entire agency to deal with it.
In 2010, the Culpeper County, Virginia school system banned the 50th Anniversary "Definitive Edition" of Anne Frank: The Diary of a Young Girl, due to "complaints about its sexual content and homosexual themes."[49] This version "includes passages previously excluded from the widely read original edition.... Some of the extra passages detail her emerging sexual desires; others include unflattering descriptions of her mother and other people living together."[50] After consideration, it was decided a copy of the newer version would remain in the library and classes would revert to using the older version.
The worst example was the pogrom in the town of Kielce in Poland on July 4th, 1946. When the 200 surviving Jews returned to their village, the local Poles who were upset to see that any had survived instigated a blood libel—accusing the Jews of the kidnap and ritual murder of Polish child. In the ensuing violence 40 of the Jews, all Holocaust survivors, were murdered by the Polish towns people.

Bureaucrats in the Reichsbahn performed important functions that facilitated the movement of trains. They constructed and published timetables, collected fares, and allocated cars and locomotives. In sending Jews to their death, they did not deviate much from the routine procedures they used to process ordinary train traffic.
With the appointment in January 1933 of Adolf Hitler as Chancellor of Germany, and the establishment of the Third Reich, German leaders proclaimed the rebirth of the Volksgemeinschaft ("people's community").[75] Nazi policies divided the population into two groups: the Volksgenossen ("national comrades") who belonged to the Volksgemeinschaft, and the Gemeinschaftsfremde ("community aliens") who did not. Enemies were divided into three groups: the "racial" or "blood" enemies, such as the Jews and Roma; political opponents of Nazism, such as Marxists, liberals, Christians, and the "reactionaries" viewed as wayward "national comrades"; and moral opponents, such as gay men, the work shy, and habitual criminals. The latter two groups were to be sent to concentration camps for "re-education", with the aim of eventual absorption into the Volksgemeinschaft. "Racial" enemies could never belong to the Volksgemeinschaft; they were to be removed from society.[76]
Political dissidents, trade unionists, and Social Democrats were among the first to be arrested and incarcerated in concentration camps. Under the Weimar government, centuries-old prohibitions against homosexuality had been overlooked, but this tolerance ended violently when the SA (Storm Troopers) began raiding gay bars in 1933. Homosexual intent became just cause for prosecution. The Nazis arrested German and Austrian male homosexuals—there was no systematic persecution of lesbians—and interned them in concentration camps, where they were forced to wear special yellow armbands and later pink triangles. The goal of persecuting male homosexuals was either for reeducation—what might now be called conversion therapy—or punishment. Jehovah’s Witnesses were a problem for the Nazis because they refused to swear allegiance to the state, register for the draft, or utter the words “Heil Hitler.” As a result, the Nazis imprisoned many of the roughly 20,000 Jehovah’s Witnesses in Germany. They could be released from concentration camps if they signed a document renouncing their faith and promising not to proselytize. Few availed themselves of that option, preferring martyrdom to apostasy. Germans of African descent—many of whom, called “Rhineland bastards” by the Nazis, were the offspring of German mothers and French colonial African troops who had occupied the Rhineland after World War I—were also persecuted by the Nazis. Although their victimization was less systematic, it included forced sterilization and, often, internment in concentration camps. The fear was that they would “further pollute” and thereby diminish the race. The Nazis also singled out the Roma and Sinti, pejoratively known as Gypsies. They were the only other group that the Nazis systematically killed in gas chambers alongside the Jews. For the Roma and Sinti, too, racial pollution and their depiction as asocials was the justification for their persecution and murder.
The Netherlands Institute for War Documentation commissioned a forensic study of the manuscripts after the death of Otto Frank in 1980. The material composition of the original notebooks and ink, and the handwriting found within them and the loose version were extensively examined. In 1986, the results were published: The handwriting attributed to Anne Frank was positively matched with contemporary samples of Anne Frank's handwriting, and the paper, ink, and glue found in the diaries and loose papers were consistent with materials available in Amsterdam during the period in which the diary was written.[56]
By the late 1930s there was a desperate search for countries of refuge. Those who could obtain visas and qualify under stringent quotas emigrated to the United States. Many went to Palestine, where the small Jewish community was willing to receive refugees. Still others sought refuge in neighbouring European countries. Most countries, however, were unwilling to receive large numbers of refugees.
It is estimated that by 1942 Einsatzgruppen had killed more than 1 million Soviet troops. These victims were either shot or gassed. Jews were not the only ones killed. People who opposed Hitler were also murdered. 20th century techniques of mass production were applied in the Final Solution. Engineers of the Final Solution used these ways to cheaply and efficiently murder millions of Jews there were many ways the Nazis murdered people. Some ways were crematoriums, electrocution, injections, flame throwers, hand grenades, and gas chambers. Units of the S.S. that were specially trained followed German troops called the first wave. These squads made up the Einsatzgruppen. Nazis genocide was targeted towards Jews mass murder was targeted towards other Non-Aryans.      

After the Nuremberg war crimes trials finished, the United States spearheaded the effort to end genocide and become a champion for the prevention of crimes against humanity. The U.S. pushed for greater international effort, helping to draft the 1948 Genocide Convention. President Harry Truman addressed Congress urging the Convention’s passage. He stressed the role the United States had to play in “outlawing the world-shocking crime of genocide.”

In 1935, Mengele earned a PhD in anthropology from the University of Munich.[7] In January 1937, he joined the Institute for Hereditary Biology and Racial Hygiene in Frankfurt, where he worked for Dr. Otmar Freiherr von Verschuer, a German geneticist with a particular interest in researching twins.[7] As von Verschuer's assistant, Mengele focused on the genetic factors that result in a cleft lip and palate, or a cleft chin.[10] His thesis on the subject earned him a cum laude doctorate in medicine (MD) from the University of Frankfurt in 1938.[11] (Both of his degrees were revoked by the issuing universities in the 1960s.)[12] In a letter of recommendation, von Verschuer praised Mengele's reliability and his ability to verbally present complex material in a clear manner.[13] The American author Robert Jay Lifton notes that Mengele's published works were in keeping with the scientific mainstream of the time, and would probably have been viewed as valid scientific efforts even outside Nazi Germany.[13]
