After WWII ended, a major concern was understanding what caused a war that cost the lives of an estimated 50–56 million military and civilians, with an additional estimated 19–28 million deaths from war-related disease and famine. Historians have documented that towards the end of the war, when the Nazis had to make the choice between winning the war and killing Jews, destroying the Jews was the priority.

One claim is that Hitler hated Jews because of some very bad past experience with them. Actually, according to the documented evidence, Hitler’s experiences with Jews were consistently positive. When Hitler lived in Männerheim Brigittenau hostel in Brigittenau, Vienna, a number of Jews lived there with whom he was on excellent terms. Most of his paintings were sold by Jewish dealers that Hitler was also on good terms with. One of the most loyal buyers of his paintings in Vienna was the Jew, Samuel Morgenstern. Hitler even expressed his admiration for Rothschild for sticking to his religion, even though this meant he could not use the German courts to settle valid grievances.

Throughout most of 1918, the Jew Lt. Hugo Gutmann (1880 –1962) served as Adolf Hitler's direct superior. Gutmann later recommended Hitler for the award of the Iron Cross First Class (a decoration rarely awarded to persons of Hitler's low Gefreiter rank). The decoration was presented to Hitler in August 1918 by the regimental commander, Major von Tubeuf. Hitler wore this medal throughout the remainder of his career, including while serving as Führer of Nazi Germany. In 1938, Gutmann was arrested by the Gestapo, but released as a result of SS personnel who knew his history. Gutmann, due to Hitler's intervention, received a full pension from Nazi Germany until the end of the Second World War.

    Hitler’s mother’s doctor was the Linz physician, the Jew Eduard Bloch (1872 –1945). He was also the family doctor of Adolf Hitler and his family when they lived in Linz until 1907. Bloch had a special fondness for the Hitler family. When Hitler's mother, Klara, was dying of breast cancer, Bloch billed the family at a reduced cost, sometimes even refusing to bill them outright. In 1908, Hitler wrote Bloch, assuring him of his gratitude for his loving care given to his mother when she was ill, a reverence that Hitler expressed with gifts. One gift was a valuable large wall painting which, according to Bloch's daughter, Gertrude (Trude) Kren (born 1903 in Austria; died 1992 in the U.S.), was lost. As late as 1937, Hitler was concerned about Bloch's well-being and called him an Edeljude ("noble Jew").
   
    When the Nazis annexed Austria in 1938, the 66-year-old Bloch wrote to Hitler asking for protection. In response, Hitler awarded Bloch special protection and personally intervened to ensure his safety. Bloch stayed in his house with his wife undisturbed until the formalities for his emigration to the United States were completed. Without any interference, they were able to sell their family home at market value, highly unusual with the distress sales of emigrating Jews at the time, and Nazi expropriation of Jewish assets through the Reich Flight Tax. Moreover, the Bloch’s were allowed to take the equivalent of 16 Reichsmarks out of the country. The usual amount allowed to Jews was a mere 10 Reichsmarks.

    Bloch lived in the United States until his death in 1945 from stomach cancer. Many more examples could be cited. Furthermore, I was unable to find a single example of a negative experience Hitler had with Jews. The reasons for Hitler’s determination to eliminate Jews include he was fully convinced that they were, except Edeljudes, an inferior race and had to be exterminated in the Nazi’s goal of producing a superior race based on Darwinism. In this conclusion he had the support of academia,
