Historic views of appeasement and the guarantee of Poland[edit]
A major historiographical debate about Chamberlain's foreign policy was triggered in 1976 by the American historian Simon K. Newman's book March 1939. Newman denied there was ever a policy of appeasement as popularly understood. Newman maintained that British foreign policy under Chamberlain aimed at denying Germany a "free hand" anywhere in Europe, and to the extent that concessions were offered they were due to military weaknesses, compounded by the economic problems of rearmament.
Most controversially, Newman contended that the British guarantee to Poland in March 1939 was motivated by the desire to have Poland as a potential anti-German ally, thereby blocking the chance for a German-Polish settlement of the Danzig (modern Gdańsk, Poland) question by encouraging what Newman claimed was Polish obstinacy over the Danzig issue, and thus causing World War II.
Newman argued that German-Polish talks on the question of returning Danzig had been going well until Chamberlain's guarantee, and that it was Chamberlain's intention to sabotage the talks as a way of causing an Anglo-German war.
In Newman's opinion, the guarantee of Poland was meant by Chamberlain as a "deliberate challenge" to start a war with Germany in 1939. In this way, Newman argued that World War II, far from being a case of German aggression was really just an Anglo-German struggle for power. Newman wrote that World War II was not "Hitler's unique responsibility..." and rather contended that "Instead of a German war of aggrandizement, the war become one of Anglo-German rivalry for power and influence, the culmination of the struggle for the right to determine the future configuration of Europe".
The "Newman controversy" caused much historical debate about what were Chamberlain's reasons for the "guarantee" of Poland in March 1939, with some reviewers arguing that Newman had failed to support his case with sufficient evidence,] whilst the Polish historian Anna Cienciala described Newman's views as wrong, and argued the British and French wanted to avoid war by pressuring the Poles to make concessions
Recently, Newman’s book was cited by the American journalist Patrick Buchanan in his 2008 book Churchill, Hitler, and "The Unnecessary War" to lend support to his assertion that the British guarantee of Poland in March 1939 was an act of folly that caused an "unnecessary war" with Germany.
