, China project manager and senior analyst

An overwhelming majority of NPT member states agree that keeping nuclear weapons on hair-trigger alert presents an irresponsibly high risk of an accidental or mistaken launch. The final report of the last NPT review conference, held in 2010, included a requirement to lower alert levels. The United States is doing its best to make sure that requirement is stripped from the final language of the 2015 report, despite the wishes of many close U.S. allies. Read more >
