There is now all this patriotic indignation about the Japanese attack on Pearl Harbor and Japanese expansionism in Asia. Yet not a word about American and European expansionism in the same area.... We must make a start. We must renounce war as an instrument of policy.... Even as I speak to you I may be guilty of what some men call treason.... You young men should refuse to take up arms. Young women tear down the patriotic posters. And all of you — young and old — put away your flags.
Speech to Liberal-Socialist Alliance, New York City (8 December 1941), as quoted in From Megaphones to Microphones (2003) by Sandra J. Sarkela et al.
