Jane Fonda’s visit to Hanoi in July, 1972, and her pro-North Vietnamese, anti-American conduct, especially her pose with an anti-aircraft gun used to shoot down American planes and her propaganda broadcasts directed toward American troops, angered many Americans. In their eyes, she was guilty of treason, but she was never charged by the American legal system. Instead, she has made millions, been the recipient of countless awards, and remained an honored American icon. This work investigates Fonda’s activities in North Vietnam and argues that she could have been indicted for treason, that there would have been enough evidence to take the case to a jury, that she could have been convicted, and that a conviction probably would have been upheld on appeal. It also considers Fonda’s early life and the effect it had on her behavior and beliefs in her later years, her audience of American POWs who were forced by the Vietnamese to listen to her broadcasts condemning them as war criminals, her arrival in Vietnam and how it was viewed by American servicemen and civilians, the crime of treason throughout history, and the only Congressional inquiry into her actions, which resulted in the government’s decision to take no legal action against her. Texts of Fonda’s radio broadcasts to American servicemen comprise the appendix.
