For Begin, getting to Mengele was not just a matter of the past. He equated Yasir Arafat with Hitler. “Unlike other Israelis, who saw the Holocaust as a one-time historical catastrophe,” said Shlomo Nakdimon, a prominent Israeli journalist who was close to Begin, “Begin believed with all his heart that the lesson of the Holocaust is that the Jewish people must protect themselves in their own country in order to prevent a renewed threat to their existence.”
Josef Mengele had hoped to use the “research” he had garnered in Auschwitz in order to produce his Habilitation, a second, post-doctoral, dissertation required for admission to a university faculty as a professor in German-speaking lands. Instead, in January 1945, as the Soviet Army advanced through western Poland, Mengele fled Auschwitz. He spent the next few weeks at the Gross-Rosen concentration camp, until its evacuation. He then made his way west to evade capture by Soviet forces.
At the same time, a carefully orchestrated smear campaign under the direction of Propaganda Minister Joseph Goebbels portrayed Jews as enemies of the German people. Daily anti-Semitic slurs appeared in Nazi newspapers, on posters, the movies, radio, in speeches by Hitler and top Nazis, and in the classroom. As a result, State-sanctioned anti-Semitism became the norm throughout Germany. The Jews lost everything, including their homes and businesses, with no protest or public outcry from non-Jewish Germans. The devastating Nazi propaganda film The Eternal Jew went so far as to compared Jews to plague carrying rats, a foreshadow of things to come.
In 1935, Mengele earned a PhD in anthropology from the University of Munich. 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. As von Verschuer's assistant, Mengele focused on the genetic factors that result in a cleft lip and palate, or a cleft chin. His thesis on the subject earned him a cum laude doctorate in medicine (MD) from the University of Frankfurt in 1938. (Both of his degrees were revoked by the issuing universities in the 1960s.) In a letter of recommendation, von Verschuer praised Mengele's reliability and his ability to verbally present complex material in a clear manner. 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.
