This was written not in the Soviet Union or one of its satellites, but in New York in 1947 by Robert Warshow in Commentary magazine about the American culture of the previous decade. While slightly hyperbolic (the Southern Agrarians, the American Scholar, etc.?) it faithfully describes American Jewish culture of the time, emphatically including its Yiddish branch. At the extreme of this movement were people like Julius Rosenberg, George Koval, and Mark Zborowski, who actively spied for the Soviet Union. At the same time, editors of Communist publications, Hollywood and union activists, party writers and institutional leaders were all directed by Moscow and were joined by rank-and-file members in promoting the virtues of Stalinism over the evils of American constitutional democracy.
