in 1919 showing an increasing obsession with antisemitism. In April 1981, it was revealed that 16 of the 600 documents published in Hitler: Sämtliche Aufzeichnungen 1905-1924 were forgeries. Historikerstreit In the Historikerstreit (Historians' Dispute) of 1986-1988, Jäckel was a prominent critic of Ernst Nolte, whose theory of Nazi crimes as a reaction to Soviet crimes was denounced as ahistorical by Jäckel under the grounds that Hitler held the Soviet Union in contempt and therefore could not have possibly felt threatened by the Soviets, as Nolte suggested. Jäckel attacked Nolte's statement that Hitler had an especially-vivid fear of the Soviet "rat cage" torture by arguing that Hitler's statement of 1 February 1943 to his generals about captured German officers going off to the "rat cage" clearly meant the Lubyanka prison, and that was not, as Nolte argued, to be interpreted literally. Jäckel went on to argue that Nolte had done nothing to establish what the remarks about the "rat cage" had to do with the Holocaust. Jäckel went on to accuse Nolte of engaging in a post hoc, ergo propter hoc argument to establish the "causal nexus" between Hitler's supposed fear of the "rat cage" torture and the Holocaust. Jäckel wrote in a 1986 essay, "The Impoverished Practice of Insinuation: The Singular Aspect of National-Socialist Crimes Cannot Be Denied", first published in the Die Zeit newspaper on September 12, 1986: Hitler often said why he wished to remove and kill the Jews. His explanation is a complicated and structurally logical construct that can be reproduced in great detail. A rat cage, the murders committed by the Bolsheviks, or a special fear of these are not mentioned. On the contrary, Hitler was always convinced that Soviet Russia, precisely because it was ruled by Jews, was a defenseless colossus standing on clay feet. Aryans had no fear of Slavic or Jewish subhumans. The Jew, Hitler wrote in 1926 in Mein Kampf, "is not an element of an organization, but a ferment of decomposition. The gigantic empire in the East is ripe for collapse." Hitler still believed this in 1941 when he had his soldiers invade Russia without winter equipment. More recently, Jäckel modified his position. He later believed that most of the initiatives for the Holocaust came from Hitler but that it was more the result of a series of ad hoc decisions than a master plan on the part of Hitler. In
