A liberal reformist core dominated antiwar activities through the end of 1966. That year the movement maintained a predominantly decentralized orientation, both lacking and resisting true national coordination. Primarily through grassroots activity, the movement incorporated new constituencies and provided alternative sources of information that challenged the government’s credibility. Antiwar activists pursued change largely through the established political system, but also in coalition building for mass demonstrations and draft resistance. Dissent within the government became more visible, which gave wartime dissent a degree of respectability. Protesting napalm production signified an early economic challenge, and the case of the Fort Hood Three exemplified cooperation between active-duty military and civilian antiwar activists. Despite continued growth and some impressive achievements, the movement also faced more significant government and right-wing opposition, and the war’s continued escalation left many activists feeling frustrated and alienated.
