evidence: Visit to Hanoi [edit]Between 1965 and 1972, almost 300 Americans – mostly civil rights activists, teachers, and pastors – traveled to North Vietnam to see firsthand the war situation with the Vietnamese. News media in the United States predominantly provided a U.S. viewpoint, and American travelers to North Vietnam were routinely harassed upon their return home.[94] Fonda also visited Vietnam, traveling to Hanoi in July 1972 to witness firsthand the bombing damage to the dikes. After touring and photographing dike systems in North Vietnam, she said the United States had been intentionally targeting the dike system along the Red River. Columnist Joseph Kraft, who was also touring North Vietnam, said he believed the damage to the dikes was incidental and was being used as propaganda by Hanoi, and that, if the U.S. Air Force were "truly going after the dikes, it would do so in a methodical, not a harum-scarum way".[95] Sweden's ambassador to Vietnam, however, observed the bomb damage to the dikes and described it as "methodic". Other journalists reported that the attacks were "aimed at the whole system of dikes".[94]
