On August 27, 1928, in Paris, with due pomp and circumstance, representatives of fifteen nations signed an agreement outlawing war. The agreement was the unanticipated fruit of an attempt by the French Foreign Minister, Aristide Briand, to negotiate a bilateral treaty with the United States in which each nation would renounce the use of war as an instrument of policy toward the other. The American Secretary of State, Frank Kellogg, had been unenthusiastic about Briand’s idea. He saw no prospect of going to war with France and therefore no point in promising not to, and he suspected that the proposal was a gimmick designed to commit the United States to intervening on France’s behalf if Germany attacked it (as Germany did in 1914). After some delay and in response to public pressure, Kellogg told Briand that his idea sounded great. Who wouldn’t want to renounce war? But why not make the treaty multilateral, and have it signed by “all the principal powers of the world”? Everyone would renounce the use of war as an instrument of policy.
