A Conference in New York
In March 1949, New York's Waldorf-Astoria Hotel played host to one of the strangest gatherings in American history. Less than four years after Allied troops had liberated Hitler's concentration camps, 800 prominent literary and artistic figures congregated in the Waldorf to call for peace at any price with Stalin, whose own gulag had just been restocked with victims of his latest purge. Americans, including Lillian Hellman, Aaron Copland, Arthur Miller, and a young Norman Mailer, joined with European and Soviet delegates to repudiate "US warmongering." Russian composer Dmitri Shostakovich told the delegates that "a small clique of hatemongers" was preparing a global conflagration; he urged progressive artists to struggle against the new "Fascists'' who were seeking world domination. American panelists echoed the Russian composer's fear of a new conflict. Playwright Clifford Odets denounced the ``enemies of Man'' and claimed the United States had been agitated into ``a state of holy terror'' by fraudulent reports of Soviet aggression; composer Copland declared "the present policies of the American Government will lead inevitably into a third world war."
