The ACCF and CCF were organizations that, during the Cold War, sought to encourage intellectuals to be critical of the Soviet Union and Communism, and to combat, according to a writer for The New York Times, "the continuing strength of the Soviet myth among the Western cultural elite.
Despite all that had happened - the Moscow show trials, the Nazi-Soviet pact, the assassination of Leon Trotsky, the Russian attack on Finland, the takeovers in Eastern Europe, the mounting evidence of the gulag - Joseph Stalin still retained the loyalty of many writers, artists and scientists who viewed the Soviet Union as a progressive alternative to the 'reactionary,' 'war-mongering' United States.
[2] Within the American committee, ex-communist intellectuals affirmed most vehemently the need for resistance to communism: Franz Borkenau (member of the Communist Party of Austria until 1929), Sidney Hook (Communist fellow traveler in the 1920s); Arthur Koestler (member of the Communist Party of Germany from 1931 to 1938) and James Burnham (member of the Fourth International from 1934 to 1940).
Koestler and Borkenau fully supported the idea of setting up a frontal opposition movement to international communism.
James Burnham, who worked for the CIA, was a member until he left the group circa 1954.
