Cesarani notes that by 1943, as the military position of the German forces deteriorated, the Nazi leadership became more openly explicit about the Final Solution. In March, Goebbels confided to his diary: "On the Jewish question especially, we are in it so deeply that there is no getting out any longer. And that is a good thing. Experience teaches that a movement and a people who have burned their bridges fight with much greater determination and fewer constraints than those that have a chance of retreat."[127]
The wounds of the Holocaust–known in Hebrew as Shoah, or catastrophe–were slow to heal. Survivors of the camps found it nearly impossible to return home, as in many cases they had lost their families and been denounced by their non-Jewish neighbors. As a result, the late 1940s saw an unprecedented number of refugees, POWs and other displaced populations moving across Europe.
But throughout Nazi-occupied Europe, relatively few non-Jewish persons were willing to risk their own lives to help the Jews. Notable exceptions included Oskar Schindler, a German who saved 1200 Jews by moving them from Plaszow labor camp to his hometown of Brunnlitz. The country of Denmark rescued nearly its entire population of Jews, over 7000, by transporting them to safety by sea. Italy and Bulgaria both refused to cooperate with German demands for deportations. Elsewhere in Europe, people generally stood by passively and watched as Jewish families were marched through the streets toward waiting trains, or in some cases, actively participated in Nazi persecutions.
One of the clearest examples of Hitler’s single-minded (and seemingly suicidal) desire to rid the world of the Jews can be seen in the extermination of the Jews of Hungary. Until March of 1944, the Hungarian government had refused to allow the deportation of Hungarian Jews. It March 1944 the Germans occupied Hungary and by mid May ( two weeks before D Day) the mass deportations to Auschwitz. The Nazi leadership worked with particular intensity. The Soviet army was rapidly approaching Hungary and the Germans knew that they were going to lose the war. But there was no way that Hitler could allow such a large Jewish community to survive. He diverted trains that were badly needed to transport more soldiers to the Russian front just to send more Jews to Auschwitz. To him, the greater enemy was the Jew.

Often the rescuers did not previously know the Jews they saved. In this type of situation, the Gentile frequently acted “spontaneously” and even “impulsively” to help a Jew. Tec writes that Gentile friends of Jews typically did not help their Jewish friends. “Helping Jews did not qualify as behaviour required from friends. The rescuer of Jews had to be propelled by other forces, forces that went beyond the usual expectations of personal friendship.”
^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]
Resistance movements also helped Jews. Sometimes, this aid was intended to help the Jews; often it was rendered in the context of the general anti-Nazi resistance. In Yugoslavia, Serbian partisans attacked a concentration camp near Nish in 1941, freeing a small number of Jews. On April 19, 1943, the Committee for Jewish Defense, aided by Christian railroad workers, attacked a Belgian transport leaving Malines for Auschwitz. Several hundred Jewish deportees escaped with the help of the Belgian resistance.
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]
