The Germans invaded the Netherlands, Luxembourg, Belgium, and France in May 1940. In the Netherlands, the Germans installed Arthur Seyss-Inquart as Reichskommissar, who quickly began to persecute the approximately 140,000 Dutch Jews. Jews were forced out of their jobs and had to register with the government. Non-Jewish Dutch citizens protested these measures, and in February 1941 they staged a strike that was quickly crushed.[161] After Belgium's surrender at the end of May 1940, it was ruled by a German military governor, Alexander von Falkenhausen, who enacted anti-Jewish measures against the country's 90,000 Jews, many of whom were refugees from Germany or Eastern Europe.[162]

…selected by the camp doctor, Josef Mengele, for medical experiments. Auschwitz doctors tested methods of sterilization on the prisoners, using massive doses of radiation, uterine injections, and other barbaric procedures. Experiments involving the killing of twins, upon whom autopsies were performed, were meant to provide information that would supposedly lead…
The entry of the U.S. into the War is also crucial to the time-frame proposed by Christian Gerlach, who argued in his 1997 thesis,[122] that the Final Solution decision was announced on 12 December 1941, when Hitler addressed a meeting of the Nazi Party (the Reichsleiter) and of regional party leaders (the Gauleiter).[123][a] The day after Hitler's speech, on 13 December 1941 Joseph Goebbels wrote in his diary:[125]
At least 130 Righteous Gentiles have settled in Israel. They were welcomed by Israeli authorities, and were granted citizenship. In the mid-1980s, they became entitled to special pensions. Some of them settled in British Mandatory Palestine before Israel's establishment shortly after World War II, or in the early years of the new state of Israel, while others came later. Those who came earlier often spoke fluent Hebrew and have integrated into Israeli society.[6]

A German mother shields the eyes of her son as they walk with other civilians past a row of exhumed bodies outside Suttrop, Germany. The bodies were those of 57 Russians killed by German SS troops and dumped in a mass grave before the arrival of troops from the U.S. Ninth Army. Soldiers of the 95th Infantry division were led by informers to the massive grave on May 3, 1945. Before burial, all German civilians in the vicinity were ordered to view the victims. #

While the Nazi Party program adopted in February 1920 did not contain direct or indirect reference to the term, Nazi propaganda presented a radical elimination of anything deemed Jewish from all aspects of German life as prerequisite for national recovery. After Hitler's rise to power, party activists and bureaucrats competed in transforming the broad-based consensus that something had to be done about the "Jewish question" into government policy aimed at varying degrees of segregation, expropriation, and physical removal. In the process, applying force became increasingly attractive; however, use of the term in German documents produced prior to 1941 should be understood less as an expression of a preconceived blueprint for genocide than as an expression of radical, as yet unspecified intent.

The Nazis used the phrase Lebensunwertes Leben (life unworthy of life) in reference to the disabled and mentally ill.[92] On 14 July 1933, the Law for the Prevention of Hereditarily Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses), the Sterilization Law, was passed, allowing for compulsory sterilization.[93][94] The New York Times reported on 21 December that year: "400,000 Germans to be sterilized".[95] There were 84,525 applications from doctors in the first year. The courts reached a decision in 64,499 of those cases; 56,244 were in favor of sterilization.[96] Estimates for the number of involuntary sterilizations during the whole of the Third Reich range from 300,000 to 400,000.[97]
On July 17, 1941, four weeks after the invasion of the Soviet Union, Hitler tasked SS chief Heinrich Himmler with responsibility for all security matters in the occupied Soviet Union. Hitler gave Himmler broad authority to physically eliminate any perceived threats to permanent German rule. Two weeks later, on July 31, 1941, Nazi leader Hermann Goering authorized SS General Reinhard Heydrich to make preparations for the implementation of a "complete solution of the Jewish question."

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.
To be sure, the names of these latter figures would be remembered regardless of what good they have done the Jews. Part of the message of singling out Harbonah, then, lies precisely in the fact that unlike them, he is a minor character. Today, not everyone who writes a small check to Christians United for Israel, or shares an article on Facebook criticizing the anti-Semitism of Ilhan Omar or Jeremy Corbyn, can be known to posterity. But in the midst of the Purim celebrations of Jewish redemption, they, too, deserve to be remembered for the good.
Despite the overwhelming odds, individual rescues sometimes succeeded, especially if the Jewish fugitives could pass as natives in language, manner, and appearance; if the hideout was skillfully camouflouged; if the local population was sympathetic; if geography and distance from neighboring homes aided concealment; and if organized groups or sympathetic friends provided additional safe houses and forged ration papers for essentials like food and clothing.
In June 1941 Germany attacked the Soviet Union and began the "Final Solution." Four mobile killing groups were formed called Einsatzgruppen A, B, C and D. Each group contained several commando units. The Einsatzgruppen gathered Jews town by town, marched them to huge pits dug earlier, stripped them, lined them up, and shot them with automatic weapons. The dead and dying would fall into the pits to be buried in mass graves. In the infamous Babi Yar massacre, near Kiev, 30,000-35,000 Jews were killed in two days. In addition to their operations in the Soviet Union, the Einsatzgruppen conducted mass murder in eastern Poland, Estonia, Lithuania and Latvia. It is estimated that by the end of 1942, the Einsatzgruppen had murdered more than 1.3 million Jews.

Peter Hayes (How Was It Possible? A Holocaust Reader, 2015): "The Holocaust, the Nazi attempt to eradicate the Jews of Europe, has come to be regarded as the emblematic event of Twentieth Century ... Hitler's ideology depicted the Jews as uniquely dangerous to Germany and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it. The threat posted by supposedly corrupting but generally powerless Sinti and Roma was far less, and therefore addressed inconsistently in the Nazi realm. Gay men were defined as a problem only if they were German or having sex with Germans or having sex with Germans and considered 'curable' in most cases. ... Germany's murderous intent toward the handicapped inhabitants of European mental institutions ... was more comprehensive ... but here, too, implementation was uneven and life-saving exceptions permitted, especially in Western Europe. Not only were some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—allotted a favored place in Hitler's New Order, but the fate of most of the other Slavs the Nazis derided as sub-humans ... consisted of enslavement and gradual attrition, not the prompt massacre meted out to the Jews after 1941."[20]
Spurred on by Joseph Goebbels, Nazis used the death of vom Rath as an excuse to conduct the first State-run pogrom against Jews. Ninety Jews were killed, 500 synagogues were burned and most Jewish shops had their windows smashed. The first mass arrest of Jews also occurred as over 25,000 men were hauled off to concentration camps. As a kind of cynical joke, the Nazis then fined the Jews 1 Billion Reichsmarks for the destruction which the Nazis themselves had caused during Kristallnacht.
Half a year later, Harel was replaced by Meir Amit, who ordered the Mossad to “stop chasing after ghosts from the past and devote all our manpower and resources to threats against the security of the state.” He mandated that the agency deal with Nazis “only to the extent it is able to do so, in addition to its principal missions” and as long as “it doesn’t impinge on the other operations.”
On the eve of World War II, the Führer (supreme leader) publicly threatened the Jews of Europe during a speech in Berlin: "In the course of my life I have very often been a prophet, and have usually been ridiculed for it. During the time of my struggle for power it was in the first instance only the Jewish race that received my prophecies with laughter when I said that I would one day take over the leadership of the State, and with it that of the whole nation, and that I would then among other things settle the Jewish problem. Their laughter was uproarious, but I think that for some time now they have been laughing on the other side of their face. Today I will once more be a prophet: if the international Jewish financiers in and outside Europe should succeed in plunging the nations once more into a world war, then the result will not be the Bolshevizing of the earth, and thus the victory of Jewry, but the annihilation of the Jewish race in Europe!"

Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]
The ghettos, and the slow death they brought, were only part of the overall plan. In the months following the Wannsee Conference, three specialized killing centers, Belzec, Treblinka and Sobibor, were constructed in southeast Poland, featuring large gas chambers with adjacent crematories or burial pits for the disposal of corpses. After they became operational, the ghettos were bypassed and Jews went directly by train to the new death camps.
To murder the Jews of "Greater Germany" as well as Jews residing in German-occupied or German-influenced areas of western, southern, southeastern and northern Europe, Himmler designated Auschwitz II (Auschwitz-Birkenau) in the spring of 1942 as a killing facility. Auschwitz-Birkenau, along with the Auschwitz main camp, was subordinated to the Inspectorate of Concentration Camps in Berlin. Originally planned as a vast forced-labor camp for Soviet prisoners of war and, later for Jewish forced laborers, Auschwitz-Birkenau began to operate as a killing center in the spring of 1942. The SS authorities murdered approximately one million Jews from various European countries at Auschwitz-Birkenau, including Jews from Germany, Austria, Czechoslovakia, Norway, France, the Netherlands, Belgium, Luxemburg, German-occupied western and southwestern Poland, Yugoslavia, Greece, Italy, and Hungary.
Meanwhile they waited, trying with all their strength to survive just one more day – the slave laborers, the fortunate few still not discovered – and those confined in ghettos such as the teenager who wrote in her diary: “When we look at the fence separating us from the rest of the world, our souls, like birds in a cage, yearn to be free. How I envy the birds that fly to freedom.”
During his time at Auschwitz, Josef Mengele was not the only physician there. It is popularly believed that he was the highest-ranking physician at the camp. This is not the case. That “distinction” belonged to SS captain Dr. Eduard Wirths. Wirths’ position as garrison physician made him responsible in all medical matters for the entire camp complex.
Twins were subjected to weekly examinations and measurements of their physical attributes by Mengele or one of his assistants.[49] The experiments he performed on twins included unnecessary amputation of limbs, intentionally infecting one twin with typhus or some other disease, and transfusing the blood of one twin into the other. Many of the victims died while undergoing these procedures,[50] and those who survived the experiments were sometimes killed and their bodies dissected once Mengele had no further use for them.[51] Nyiszli recalled one occasion on which Mengele personally killed fourteen twins in one night by injecting their hearts with chloroform.[31] If one twin died from disease, he would kill the other twin to allow comparative post-mortem reports to be produced for research purposes.[52]
