Buchanan argues that Hitler's public demands on Poland in 1938 and 1939, namely the return of the Free City of Danzig to the Reich, "extra-territorial" roads across the Polish Corridor, and Poland's adherence to the Anti-Comintern Pact were a genuine attempt to build an anti-Soviet German-Polish alliance, especially since Buchanan argues that Germany and Poland shared a common enemy, the Soviet Union.[14] Buchanan claims that Hitler wanted Poland as an ally against the Soviet Union, not an enemy.[15]

Buchanan agrees with the British historian E. H. Carr, who said in April 1939 about the Polish "guarantee": "The use or threatened use of force to maintain the status quo may be morally more culpable than the use or threatened use of force to alter it."[16] Buchanan maintains that Hitler did not want a war with Britain and that Britain should not have declared war in 1939 on an Anglophile Hitler who wanted to ally the Reich with Britain against their common enemy the Soviet Union.[17] Buchanan calls the Morgenthau Plan of 1944 a genocidal plan for the destruction of Germany that was promoted by the vengeful Henry Morgenthau and his deputy, the Soviet agent Harry Dexter White, a way of ensuring Soviet domination of Europe, with Churchill being amoral for accepting it.[18]

Buchanan argues that the Holocaust would not have developed the scale that it did without Hitler's invasion of Poland and then the Soviet Union, as he would not otherwise have been in control of most European Jews. Buchanan argues that if Churchill had accepted Hitler's peace offer of 1940, the severity of the Holocaust would have been greatly reduced.[19]Endorsing the concept of Western betrayal, Buchanan accuses Churchill and Roosevelt of turning over Eastern Europe to the Soviet Union at the Tehran Conference and the Yalta Conference.[20]
