This paper examines the anti-Vietnam War activism of a group of American expatriates in France, the Paris American Committee to Stopwar (PACS), from its formation in 1966 to its dissolution in 1968. Using oral history and archival research, the article uses PACS’ history to further recent studies focusing on the Vietnam War as a global event. Through an evaluation of how PACS dealt with Communism, networking, military deserters and the French government, the article demonstrates how being in France benefited and limited anti-war activism while also highlighting changes in French governmental attitudes post-May 1968. In so doing, the article showcases the significance of location in determining how anti-war protest plays out. [ABSTRACT FROM AUTHOR]
