By the mid-1980s, the state-sponsored positive framing of the peaceful atom served a range of government interests. It enabled the United States and European states to use nuclear power as leverage against developing countries in a time when petroleum seemed to swing the pendulum of global resource dominance toward several so-called backward countries. It was useful to countries trying to prop up the legitimacy of their nuclear weapons programs, while secretly working on bombs, and it provided environmental arguments to those whose priority was actually energy security. The peaceful atom’s promise of plenty helped to maintain a veneer of credibility for the Treaty on the Non-Proliferation of Nuclear Weapons, at a time when the IAEA seemed to have become the treaty’s policing instrument. The more the United States relied on the IAEA, the more it recommitted to making promises of peaceful nuclear technology, especially to the developing world.
