During 1936, Pohl joined the Young Communist League because of its positions for unions and against racial prejudice, Adolf Hitler, and Benito Mussolini. He became president of the local Flatbush III Branch of the YCL in Brooklyn. Pohl has said that after the Molotov–Ribbentrop Pact of 1939, the party line changed and he could no longer support it, at which point he left.
