Inside the Arms Control Association

The 1968 nuclear Nonproliferation Treaty (NPT) has served as the essential framework and catalyst, albeit an imperfect one, for global efforts to stop the spread of nuclear weapons, end nuclear testing, and advance disarmament diplomacy to help achieve a world free of nuclear weapons. 

For the first time in many decades, there are no legally-binding limits on U.S. and Russian nuclear arsenals and there are no active negotiations to establish new nuclear arms control constraints. A post-New START nuclear weapons buildup is now possible but is by no means inevitable.
