In his younger years Lyons was a member of the Young People’s Socialist League the youth section of the Socialist Party USA.
He became critical of the Soviet Union after working there as a correspondent of United Press International.
During the early 1940s and the Second Red Scare which followed World War II, Lyons was a frequent contributor to the popular press on anti-Communist themes, targeting liberals if Lyons deemed them inadequate in their denunciations of the Soviet regime.
Lyons also wrote a biography of President Herbert Hoover.
Lyons presents a fact-filled and tightly argued critique of the Soviet Union. As a Communist, Lyons wrote favorably of the USSR and Stalin in the 20's and 30's, including in his experience an extended stay in the country and a widely acclaimed personal interview with Stalin. Lyons was in a special position to evaluate the Soviet Unions promises versus performance. It was a great read.
