‘We are not a rich country to waste our resources on expensive toys’: Mexico’s version of Atoms for Peace

Abstract

The Atoms for Peace initiative was announced by U.S. President Dwight D. Eisenhower in his speech to the United Nations General Assembly on 8 December 1953. The ways in which Eisenhower’s proposal was interpreted, adapted and reshaped by different countries allows us to understand the various meanings and uses of nuclear technologies, particularly in Third World countries. Mexico’s version of the initiative was related to its modernizing nationalism, a distaste for overt geopolitical alignment and nuclear weapons, and an intermittent commitment of the federal government with nuclear technologies. These ingredients eventually led to the promotion of the Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean, known as the Treaty of Tlatelolco (TT) signed in Mexico City in 1967. The TT made Latin America the first nuclear weapons-free populated region in the world, thus positioning Mexico in the new geopolitical nuclear order through a denuclearization discourse and a policy of non-engagement with nuclear technologies.
