The Soviet Union and Nuclear Proliferation

Prevention of the spread of nuclear weapons has long been a theme of the Soviet! Union's declaratory arms control policy. It has also found concrete expression in Moscow's endorsement of the Partial Test Ban Treaty of 1963, the Treaty for the Prohibition of Nuclear Weapons in Latin America of 1967 (Treaty of Tlatelolco), the Nuclear Nonproliferation Treaty of 1968, and, since 1958, in the stringent nuclear export policy of the Soviet Union. Although much of Moscow's nonproliferation rhetoric and elements of its nonproliferation behavior can be explained in terms of narrow self-interest (namely, prevention of access to nuclear weapons by traditional adversaries), the range and consistency of its nonproliferation efforts, as well as certain specific actions, indicate that the Soviet leadership appreciates the dangers posed by the diffusion of nuclear weapons.
