Abstract

The Second World War offered an excellent opportunity for some U.S. think tanks to influence foreign-policy-making processes and get involved in transatlantic diplomacy. This study seeks to demonstrate that the Council on Foreign Relations (CFR) challenged the stalemate between the U.S. and French authorities by gathering together U.S. experts and non-collaborationist French leaders. A first-hand reconstruction of this informal network is based on the unreleased Peace Aims Group’s records. This was a unique CFR exchange programme for European governments-in-exile’s representatives. In the first part, a general reconstruction of Council on Foreign Relations’ planning introduces an original assessment of the meetings with some prominent French intellectuals and politicians. It is argued that these conferences can be interpreted as rare examples of wartime public diplomacy. The second part discloses new historical evidence demonstrating the participation of Jean Monnet in a Peace Aims session. This discovery proves the existence of a long-term partnership between one of the key protagonists of the European integration process and the most authoritative foreign-policy think tank working for the Roosevelt administration. Overall, the analysis of Peace Aims Group’s off-the-record discussions sheds new light on the WWII transatlantic debate on postwar Europe and France.
