Ken Burns and Lynn Novick’s PBS documentary series “The Vietnam War” digs into Fonda’s 1972 visit to North Vietnam in Episode 9, titled “A Disrespectful Loyalty.” Although many of her actions, including speaking on Radio Hanoi and denying the reported conditions of American POWS, drew criticism, it was her posing for a photo on a North Vietnamese anti-aircraft gun that sparked widespread hatred among veterans and the South Vietnamese alike, and earned her the nickname “Hanoi Jane.”
