Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

In the 1970s, nuclear-power boosters expected that by now nuclear power would produce perhaps 80 to 90 percent of all electrical energy globally. Today, the official high-growth projection of the Organization for Economic Co‑operation and Developments (OECD) Nuclear Energy Agency (NEA) estimates that nuclear power plants will generate about 20 percent of all electrical energy in 2050. Thus, nuclear power could make a significant contribution to the global electricity supply. Or it could be phased out — especially if there is another accidental or a terrorist-caused Chernobyl-scale release of radioactivity. If the spread of nuclear energy cannot be decoupled from the spread of nuclear weapons, it should be phased out.

A universal Fissile Material Cut-off Treaty (FMCT), which would ban the production of fissile material (separated plutonium, highly enriched uranium (HEU), and uranium-233) for nuclear weapons, has long been seen as a key building block in nuclear disarmament and non-proliferation.
