Nuclear Weapons
By the late 1960s, it became apparent that while the arms race between the United States and Soviet Union was yielding thousands of additional nuclear weapons, it was not leading to greater security for either country or the world at-large.
Thus, in 1968, the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the NPT, was opened for signature. In addition to establishing an international commitment to nonproliferation, the NPT laid the groundwork for eventual disarmament by all existing nuclear states. This disarmament vision was embodied in Article VI, which called upon signatories to negotiate "effective measures relating to cessation of the nuclear arms race" as well as "general and complete disarmament."
The NPT served as a prelude to the first round of Strategic Arms Limitations Talks (SALT I) between the U.S. and Soviet Union. On May 26, 1972, SALT I produced bilateral pledges to freeze at existing levels the number of strategic ballistic missile launchers possessed by each country and to take other steps to mitigate the arms race. Most notably, SALT I also produced the Anti-Ballistic Missile (ABM) Treaty banning missile defense systems as well as an interim agreement on strategic offensive arms.
In the past 30 years, various important agreements were negotiated and signed between the United States, Soviet Union (and its successor states), and other parties to reduce strategic nuclear stockpiles. These include the Intermediate-Range Nuclear Forces (INF) Treaty, Strategic Arms Reduction Talks I (START I) and the Lisbon Protocol, Strategic Arms Reduction Talks II (START II), Strategic Arms Reduction Talks III (START III), and the Strategic Offensive Reductions Treaty (SORT or Moscow Treaty).
