Abstract
Sartre's interventions at the Vienna, Berlin, and Helsinki Congresses of the World Peace Council are examined in depth. Neglected and overlooked for over a half-century, it is argued that the themes Sartre elaborated in these speeches were consonant with the political and intellectual projects he had been developing since the mid-1930s. Although Sartre spoke as a Marxist who had allied himself with the Communist Party, his deepest concern was to build international unity in opposition to the escalating threat of nuclear war, and to restore political and economic sovereignty to a Western Europe crushed by dependency on America. Freedom for all the world's peoples, Sartre argued, depended on mutual interdependence between nations, built from the ground up by the popular masses
