Although many or even most of the editors and writers had been socialists, Trotskyites, or Stalinists in the past, that was no longer tolerated. "Commentary" articles were anti-Communist and also anti-McCarthyite; it identified and attacked any perceived weakness among liberals on Cold War issues, backing President Harry Truman's policies such as the Truman Doctrine, the Marshall Plan, and NATO. The "soft-on-Communism" position of the Congress of Industrial Organizations (CIO) and Henry A. Wallace came under steady attack. Liberals who hated Joseph McCarthy were annoyed when Irving Kristol wrote at the height of the controversy that "there is one thing that the American people know about Senator McCarthy: he, like them, is unequivocally anti-Communist. About the spokesmen for American liberalism, they feel they know no such thing."
