For a period, Fromm was also active in U.S. politics. He joined the Socialist Party of America in the mid-1950s, and did his best to help them provide an alternative viewpoint to McCarthyist trends in some US political thought. This alternative viewpoint was best expressed in his 1961 paper "May Man Prevail? An Inquiry into the Facts and Fictions of Foreign Policy". However, as a co-founder of SANE, Fromm's strongest political activism was in the international peace movement, fighting against the nuclear arms race and U.S. involvement in the Vietnam War. After supporting Senator Eugene McCarthy's losing bid for the Democratic presidential nomination, Fromm more or less retreated from the American political scene, although he did write a paper in 1974 entitled "Remarks on the Policy of Détente" for a hearing held by the U.S. Senate Committee on Foreign Relations. Fromm was awarded Nelly Sachs Prize in 1979.
