Romania implemented anti-Jewish measures in May and June 1940 as part of its efforts towards an alliance with Germany. Jews were forced from government service, pogroms were carried out, and by March 1941 all Jews had lost their jobs and had their property confiscated.[169] After Romania joined the invasion of the Soviet Union in June 1941, at least 13,266 Jews were killed in the Iași pogrom,[170] and Romanian troops carried out massacres in Romanian-controlled territory, including the Odessa massacre of 20,000 Jews in Odessa in late 1941. Romania also set up concentration camps under its control in Transnistria, where 154,000–170,000 Jews were deported from 1941 to 1943.[169]

Every detail of the actual extermination process was meticulously planned. Jews arriving in trains at Belzec, Sobibor, and Treblinka were falsely informed by the SS that they had come to a transit stop and would be moving on to their true destination after delousing. They were told their clothes were going to be disinfected and that they would all be taken to shower rooms for a good washing. Men were then split up from the women and children. Everyone was taken to undressing barracks and told to remove all of their clothing. Women and girls next had their hair cut off. First the men, and then the women and children, were hustled in the nude along a narrow fenced-in pathway nicknamed by the SS as the Himmelstrasse (road to Heaven). At the end of the path was a bathhouse with tiled shower rooms. As soon as the people were all crammed inside, the main door was slammed shut, creating an air-tight seal. Deadly carbon monoxide fumes were then fed in from a stationary diesel engine located outside the chamber.
Here the prophet Isaiah is offering reassurance to two classes of people. The first is the nekhar, or alien, a word that in this context clearly refers to a Gentile (as it does elsewhere in the Bible). While such a person—the reference may be to a convert or to one taking on the intermediate status of a God-fearing non-Jew—might fear that not being born a Jew places an insurmountable barrier between him and God, the prophet assures him to the contrary.
After several months on the run, including a trip back to the Soviet-occupied area to recover his Auschwitz records, Mengele found work near Rosenheim as a farmhand.[62] He eventually escaped from Germany on 17 April 1949,[63][64] convinced that his capture would mean a trial and death sentence. Assisted by a network of former SS members, he used the ratline to travel to Genoa, where he obtained a passport from the International Committee of the Red Cross under the alias "Helmut Gregor", and sailed to Argentina in July 1949.[65] His wife refused to accompany him, and they divorced in 1954.[66]
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]
