While the numbers considerably reduced through June and July [1944], nearly 440,000 Hungarian Jews were transported to Auschwitz in less than eight weeks; 320,000 were murdered. — Rawson, 144. Also in: S.J.; Carmelo Lisciotto (2007). "The Destruction of the Jews of Hungary". H.E.A.R.T. Of the 381,600 Jews who left Hungary between 15 May 1944 and 30 June 1944 it is probable that 200,000 – 240,000 were gassed or shot on 46 working days.
In the aftermath of the Holocaust, many of the survivors found shelter in displaced persons  camps administered by the Allied powers. Between 1948 and 1951, almost 700,000 Jews emigrated to Israel, including 136,000 Jewish displaced persons from Europe. Other Jewish displaced persons emigrated to the United States and other nations. The last camp for Jewish displaced persons closed in 1957.
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.”

It is not known when Hitler formed the intention of the “final solution of the Jewish question” on the scale of the European continent. The conference in Wannsee on January 20, 1942 considered only the details of the undertaking: the methods for organizing the deportation and ensuring the cooperation of the civilian administration. Overall, the plans called for the murder of 11 million Jews living in Germany, the occupied territory, the states opposed to the Third Reich, and the allied and neutral countries. 
Although many people responded with obstructionism and doubt,  several rescue operations were run throughout Axis-controlled Europe. Some were the work of prominent individuals like Raoul Wallenberg and Carl Lutz who worked largely alone while other operations were far more complex. A network of Catholic bishops and clergymen organized local protests and shelter campaigns throughout much of Europe that are today estimated to have saved 860,000 lives. Danish fishermen clandestinely ferried more than 7,000 Jews into neutral Sweden while the French town of Chambon-sur-Lignon sheltered between 3,000 and 5,000 refugees.
An Israeli historian Dina Porat claimed that the Final Solution, i.e.: "the systematic overall physical extermination of Jewish communities one after the other – began in Lithuania" during the massive German chase after the Red Army across the Baltic states in Reichskommissariat Ostland.[53] The subject of the Holocaust in Lithuania has been analysed by Konrad Kweit from USHMM who wrote: "Lithuanian Jews were among the first victims of the Holocaust [beyond the eastern borders of occupied Poland]. The Germans carried out the mass executions [...] signaling the beginning of the 'Final Solution'."[54] About 80,000 Jews were killed in Lithuania by October (including in formerly Polish Wilno) and about 175,000 by the end of 1941 according to official reports.[53]

German-occupied Denmark rescued most of its own Jews by spiriting them to Sweden by sea in October 1943. This was possible partly because the German presence in Denmark was relatively small. Moreover, while anti-Semitism in the general population of many other countries led to collaboration with the Germans, Jews were an integrated part of Danish culture. Under these unique circumstances, Danish humanitarianism flourished.
In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross 2nd Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with von Verschuer, who was now director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.[20][21][22]
