The SALT treaty was ratified in 1972, to limit offensive weapons. What does SALT abbreviate?

The Strategic Arms Limitation Treaty, or SALT, represented a pivotal effort during the Cold War to manage the escalating nuclear arms race between the United States and the Soviet Union. Ratified in 1972, this agreement aimed to limit the number of offensive strategic weapons (Review) held by both superpowers, thereby reducing the risk of a catastrophic global conflict.

"Strategic arms" specifically referred to long-range nuclear delivery systems, including intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers. By the early 1970s, both nations possessed arsenals capable of inflicting unimaginable destruction upon the other, a terrifying concept known as "mutually assured destruction," or MAD. The SALT treaty sought to stabilize this precarious balance, ensuring neither side could gain a decisive advantage that might tempt a first strike.

The first agreement, SALT I, froze the number of ballistic missile launchers at existing levels and restricted the deployment of anti-ballistic missile (ABM) systems, which were designed to shoot down incoming warheads. This landmark treaty was a product of détente, a period of eased tensions between the superpowers. It demonstrated that even fierce adversaries could find common ground on issues of existential importance, paving the way for subsequent arms control negotiations and setting a crucial precedent for international security.
