During the US War in Vietnam, diverse activists and organizations advanced a range arguments against US intervention in Vietnam. These organizations did not form a singular or united antiwar movement, however, and many histories have overlooked the contributions of activists who did not focus their efforts solely on ending the US war. Indeed, many activists challenged injustices on multiple fronts and created unique antiwar discourses as part of their social justice advocacy. They often linked their advocacy and constituents within the United States with US treatment of Vietnam and the Vietnamese. This chapter describes the diversity of antiwar rhetoric and activism in the 1960s and 1970s with the help of North Vietnam’s government, which fostered a people’s diplomacy with American citizens. In doing so, this chapter illustrates that many participants in antiwar advocacy saw their protests against US intervention in Vietnam as part of their larger fight to create a more just American society.
