In May 1925, the League of Nations convened a Conference for the Supervision of the International Trade in Arms and Ammunition and in Implements of War in Geneva, Switzerland. Six weeks of negotiations resulted in a new Arms Traffic Convention (as well as the Geneva Protocol against the usage of chemical and biological weapons), which representatives from eighteen countries—including the United States, Britain, France, Italy, and Japan—signed on June 17. The United States led the way to that moment yet did not follow through on it afterward. The treaty, which lacked robust enforcement mechanisms, languished in national legislatures and never entered into force. Even so, it had a constructive legacy: the compilation and publication of statistics on gun-running. Intelligence based on open and closed sources collected for, and resulting from, the Arms Traffic Conference, indicated systematic violations of the European peace settlements and revealed a world awash in guns.
