The Americans—and like them, the Soviets, British, and French—were not “haves” but “have-nots,” exerting their considerable diplomatic, trade, and military power to find and extract strategic materials. One strategy was to encourage the notion that peaceful applications of the atom in such countries should focus on subsistence, raw materials commodities, and basic sanitation and medicine. Such attitudes were deeply resented, and resisted, by independent former colonial states such as India, Argentina, and Brazil. In the late 1940s, when uranium seemed scarce, the US government made it policy to cast doubt on commercial uses of atomic energy and instead to trumpet the use of radioisotopes, which had potential applications in agricultural and medical research. In their quest for strategic resources to secure the weapons arsenal, US officials deemphasized industrial power and played up the ability of the atom to provide plentiful food and to improve human health.
