The British army took lessons from the successful infantry and artillery offensives on the Western Front in late 1918. To obtain the best co-operation between all arms, emphasis was placed on detailed planning, rigid control and adherence to orders. Mechanization of the army was considered a means to avoid mass casualties and indecisive nature of offensives, as part of a combined-arms theory of war.[35][36] The four editions of Field Service Regulations published after 1918 held that only combined-arms operations could create enough fire power to enable mobility on a battlefield. This theory of war also emphasized consolidation, recommending caution against overconfidence and ruthless exploitation.[37]

Dan Stone, a specialist in the historiography of the Holocaust, lists ethnic Poles, Ukrainians, Soviet prisoners of war, Jehovah's Witnesses, black Germans, and homosexuals as among the groups persecuted by the Nazis; he writes that the occupation of eastern Europe can also be viewed as genocidal. But the German attitude toward the Jews was different in kind, he argues. The Nazis regarded the Jews not as racially inferior, deviant, or enemy nationals, as they did other groups, but as a "Gegenrasse: a 'counter-race', that is to say, not really human at all". The Holocaust, for Stone, is therefore defined as the genocide of the Jews, although he argues that it cannot be "properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans".[d] Donald Niewyk and Francis Nicosia, in The Columbia Guide to the Holocaust (2000), favour a definition that focuses on the Jews, Roma, and Aktion T4 victims: "The Holocaust—that is, Nazi genocide—was the systematic, state-sponsored murder of entire groups determined by heredity. This applied to Jews, Gypsies, and the handicapped."[33]
Schindler moved to West Germany after the war, where he was supported by assistance payments from Jewish relief organisations. After receiving a partial reimbursement for his wartime expenses, he moved with his wife, Emilie, to Argentina, where they took up farming. When he went bankrupt in 1958, Schindler left his wife and returned to Germany, where he failed at several business ventures and relied on financial support from Schindlerjuden ("Schindler Jews")—the people whose lives he had saved during the war. He and his wife, Emilie, were named Righteous Among the Nations by the Israeli government in 1993. He died on 9 October 1974 in Hildesheim, Germany, and was buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.
