Like many liberals and some socialists, Rustin supported President Lyndon B. Johnson's containment policy against communism, while criticizing specific conduct of this policy. In particular, to maintain independent labor unions and political opposition in Vietnam, Rustin and others gave critical support to U.S. military intervention in the Vietnam War, while calling for a negotiated peace treaty and democratic elections. Rustin criticized the specific conduct of the war, though. For instance, in a fundraising letter sent to War Resisters League supporters in 1964, Rustin wrote of being "angered and humiliated by the kind of war being waged, a war of torture, a war in which civilians are being machine gunned from the air, and in which American napalm bombs are being dropped on the villages."
