Antiwar sentiment grew during 1967. Divided over some issues, the movement’s decentralized nature resisted control by any one faction and it advanced along coexisting paths. Liberals appealed to moderates through Vietnam Summer and Negotiations Now, but by autumn, leftist influence was more pronounced. Frustrated over continued escalation, some activists engaged in more direct confrontation. Students challenged university connections to the military-industrial complex, draft resistance proliferated through organizations and individual conscience, GI dissent gained momentum, and radicals increasingly adopted civil disobedience, most evident at the March on the Pentagon. New layers of moderate antiwar opinion worked through the democratic process and street demonstrations worked in conjunction with government critics. Government officials tried to undermine this loyal opposition. Harassment ranged from infiltration and sabotage to politically influenced trials. President Johnson responded to antiwar pressure with an optimistic progress campaign that would have serious future repercussions. The movement endured these assaults as a coalition of diverse organizations and perspectives.
