Originally broadcast on KSFR's The Forum Plus, UMass historian Stephen R. Platt shares the untold story of Evans Carlson — a WWII Marine commander, secret confidant of FDR, and pioneer of U.S. special forces. Drawing on exclusive access to Carlson’s family letters, journals, and military archives, Platt reveals a hero celebrated for introducing “gung-ho” to America but later vilified during the McCarthy era for his admiration of China. This conversation explores Carlson’s daring intelligence work, his quiet influence on Roosevelt, and his vision for a better U.S.–China relationship that might have changed history.
