What treaty between the US and the Soviet Union helped reduce the threat of nuclear war?

The Strategic Arms Limitation Talks (SALT) led to the SALT I treaty in 1972, which aimed to limit the number of nuclear weapons and their delivery systems between the United States and the Soviet Union. This treaty established caps on intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs), marking a significant step towards arms control during the Cold War. Additionally, the Anti-Ballistic Missile (ABM) Treaty, signed alongside SALT I, restricted the deployment of missile defense systems, further contributing to the reduction of nuclear tensions.
