The rise of social activism in the United States in the 1960s can largely be attributed to A. US involvement in the Vietnam War. This involvement sparked widespread protests and movements, as many Americans began to question the morality and consequences of the war. Additionally, the civil rights movement, women's rights, and other social justice issues gained momentum during this decade, largely fueled by discontent with government policies and a desire for social change.
While factors like economic power and media influence played roles in society, the Vietnam War was a significant catalyst for the active engagement of citizens in various forms of activism during this period.
