Robert Kastenmeier (Dem-WI), and Abner J. Mikva (Dem-IL). The transcripts describe alleged details of U.S. military's conduct in Vietnam. Some tactics were described as "gruesome", such as the severing of ears from corpses to verify body count. Others involved the killing of civilians. Soldiers claimed to have ordered artillery strikes on villages which did not appear to have any military presence. Soldiers were claimed to use racist terms such as "gooks", "dinks" and "slant eyes" when referring to the Vietnamese. Witnesses described that legal, by-the-book instruction was augmented by more questionable training by non-commissioned officers as to how soldiers should conduct themselves. One witness testified about "free-fire zones", areas as large as in which soldiers were free to shoot any Vietnamese they encountered after curfew without first making sure they were hostile. Allegations of exaggeration of body count, torture, murder and general abuse of civilians and the psychology and motivations of soldiers and officers were discussed at length. Fulbright (end to war) In April and May 1971, the Senate Foreign Relations Committee, chaired by Senator J.

Speaking on behalf of Vietnam Veterans Against the War, he argued for the immediate, unilateral withdrawal of U.S. forces from Vietnam. During nearly two hours of discussions with committee members, Kerry related in some detail the findings of the Winter Soldier Investigation, in which veterans had described personally committing or witnessing atrocities and war crimes. Public opinion The American public's support of the Vietnam War decreased as the war continued on. As public support decreased, opposition grew. The Gallup News Service began asking the American public whether it was a "mistake to send troops to Vietnam" in August 1965. At the time less than a quarter of Americans polled, 24%, believed it was a mistake to send troops to Vietnam while 60% of Americans polled believed the opposite. Three years later, in September 1968, 54% of Americans polled believed it was a mistake to send troops to Vietnam while 37% believed it was not a mistake. A 1965 Gallup Poll asked the question, "Have you ever felt the urge to organize
