World War I
German guilt
In reaction to the orthodox interpretation enshrined in the Versailles Treaty (which declared that Germany was guilty of starting World War I), the self-described "revisionist" historians of the 1920s rejected the orthodox view and presented a complex causation in which several other countries were equally guilty. Intense debate continues among scholars.[25]
Guilt for causing World War II

The orthodox interpretation blamed Hitler and Nazi Germany and Imperial Japan for causing the war. Revisionist historians of World War II, notably Charles A. Beard, said the U.S. was partly to blame because it pressed the Japanese too hard in 1940–41 and rejected compromises.[29] Other notable contributions to this discussion include Charles Tansill, Back Door To War (Chicago, 1952); Frederic Sanborn, Design For War (New York, 1951); and David Hoggan, The Forced War (Costa Mesa, 1989). British historian A. J. P. Taylor ignited a firestorm when he argued Hitler was a rather ordinary diplomat and did not deliberately set out to cause a war.[30]
Patrick Buchanan,[31] an American conservative pundit, argued the Anglo–French guarantee to Poland in 1939 encouraged Poland not to seek a compromise over Danzig, though Britain and France were in no position to come to Poland's aid, and Hitler was offering the Poles an alliance in return. He argues that they thereby turned a minor border dispute into a catastrophic world conflict, and handed East Europe, including Poland, to Stalin. Buchanan further argued the British pact with Poland ensured the country would be invaded, as Stalin knew the British Empire would not be able to declare war on Germany and the Soviet Union in 1939.
