What arms reduction talks led to an antiballistic missile treaty?

The antiballistic missile treaty was a significant component of the arms reduction talks that took place during the Cold War. SALT I, signed in 1972, initiated the first negotiation of limits on strategic arms between the United States and the Soviet Union, leading to the Anti-Ballistic Missile Treaty. This treaty was aimed specifically at limiting the deployment of missile defense systems, which could potentially undermine the effectiveness of nuclear deterrence by allowing one side to shield itself against ballistic missile attacks.

While both SALT I and SALT II focused on arms control, the specific treaty addressing the limitations of missile defense systems is rooted in the SALT I framework. SALT II, which was signed in 1979, introduced additional limitations on strategic missile systems and warheads but did not establish a new antiballistic missile treaty, as the framework and negotiations for missile defenses were solidified during SALT I.

The START treaties (Strategic Arms Reduction Treaties) were developed later, in the late 1980s and early 1990s, focusing more on the reduction of strategic offensive arms instead of explicitly addressing missile defenses. Thus, the correct choice identifying the arms reduction talks that specifically led to the antiballistic missile treaty is indeed associated with
