Jews and Communism were just as strongly tied together in America, and for years the largest circulation Communist newspaper in our country was published in Yiddish. When they were finally released, the Venona Decrypts demonstrated that even as late as the 1930s and 1940s, a remarkable fraction of America’s Communist spies came from that ethnic background.
However, once Communism sharply fell out of favor in 1950s America, nearly all of the leading “Red Baiters” such as Sen. Joseph McCarthy went to enormous lengths to obscure the ethnic dimension of the movement they were combatting. Indeed, many years later Richard Nixon casually spoke in private of the difficulty he and other anti-Communist investigators had faced in trying to focus on Gentile targets since nearly all of the suspected Soviet spies were Jewish, and when this tape became public, his alleged anti-Semitism provoked a media firestorm even though his remarks were obviously implying the exact opposite.
