Name the international agreement reached in the 1970s to limit nuclear weapons.

The Strategic Arms Limitation Talks (SALT) refers specifically to the negotiations between the United States and the Soviet Union during the 1970s aimed at curbing the arms race in nuclear weapons, particularly strategic ballistic missiles. SALT I, signed in 1972, resulted in the Anti-Ballistic Missile (ABM) Treaty and an interim agreement that limited the number of intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs) each superpower could possess. This was a significant step in international diplomacy as it marked a formal acknowledgment by both the United States and the Soviet Union of the need to limit nuclear arms, thereby reducing the risk of nuclear confrontation.

In this context, while other treaties like the Nuclear Non-Proliferation Treaty focused on preventing the spread of nuclear weapons to other nations and promoting peaceful uses of nuclear energy, SALT was specifically concerned with the existing nuclear arsenals of the superpowers.
