Today, the 45-nation Nuclear Suppliers Group decided to approve a nuclear deal between the United States and India (which is not part of the Nuclear Non-Proliferation Treaty (NPT), and which tested bombs between 1974 and 1998). The decision is one about which I feel ambivalent. One the one hand, it might promote the relatively responsible use of nuclear technologies in India. Despite how we could probably do better by spending our money in other ways, more nuclear power is a likely consequence of concerns about both energy security and climate change. On the other hand, the deal demonstrates that it is possible states can test bombs, remain outside the NPT, and still get access to internationally-provided nuclear fuels and technologies. The lesson to other states may be that the best long-term course of action is to ignore international efforts aimed at preventing the spread of nuclear weapons.
Thinking about how many states are likely to have reactors and bombs by the end of the next century is pretty worrisome.
