NUCLEAR NON-PROLIFERATION TREATY (NPT): Allows only the nuclear weapon states to have nuclear weapons and stops others from acquiring them. For the purposes of the NPT, a nuclear weapon state is one which has manufactured and exploded a nuclear weapon or other nuclear explosive device prior to 1 January 1967. So there are five nuclear weapon states: US, USSR (later Russia), Britain, France and China. Signed in Washington, London, and Moscow on 1 July 1968. Entered into force on 5 March 1970. Extended indefinitely in 1995.

The Anti-ballistic Missile (ABM) Treaty in 1972 tried to stop the United States and Soviet Union from using ballistic missiles as a defensive shield to launch a nuclear attack. The US and Soviet Union signed a number of other arms control treaties including the Strategic Arms Limitations Treaty II or SALT II and the Strategic Arms Reduction Treaty (START).

STRATEGIC ARMS REDUCTION TREATY I (START-I) was signed in 1991. STRATEGIC ARMS REDUCTION TREATY II (START-II) was signed in 1993.

Disarmament requires all states to give up certain kinds of weapons. For example, the 1972 Biological Weapons Convention (BWC) and the 1992 Chemical Weapons Convention (CWC) banned the production and possession of these weapons. More than 155 states acceded to the BWC and 181 states acceded to the CWC. Both conventions included all the great powers. But the superpowers — the US and Soviet Union — did not want to give up the third type of weapons of mass destruction, namely, nuclear weapons, so they pursued arms control. Arms control regulates the acquisition or development of weapons.

STRATEGIC ARMS REDUCTION TREATY II (START-II): Treaty signed by the Russian President Boris Yeltsin and the US President George Bush (Senior) on the reduction and limitation of strategic offensive arms in Moscow on 3 January 1993.
