The antiwar movement became both more powerful and, at the same time, less cohesive between 1969 and 1973. Most Americans pragmatically opposed escalating the U.S. role in Vietnam, believing the economic cost too high; in November of 1969 a second march on Washington drew an estimated 500,000 participants.
The Vietnam antiwar movement, famous for its sound and fury, deserves credit for more. It were the first mass movement against a war in American history and one of its great moral crusades, yet most Americans recall only enormous protests and social chaos.
