Which treaty or talks were aimed at limiting the number of nuclear warheads and missiles between the US and the Soviet Union?

• A. SALT Talks
• B. NAFTA
• C. SDI
• D. Environmentalism

Answer: (A)

This question is about Cold War diplomacy aimed at slowing the arms race by capping the number of nuclear weapons and the missiles that carry them. The SALT talks were negotiations between the United States and the Soviet Union that led to treaties designed to limit how many strategic nuclear weapons each side could possess and how many missiles they could deploy. The result was a framework of restraints, such as caps on ICBMs and submarine-launched missiles, intended to prevent unchecked growth of arsenals.

Why this is the best fit: the essence of the SALT talks is precisely limiting the size and growth of nuclear forces through written agreements between the two powers. The other options don’t match this purpose. NAFTA is about trade among North American partners, not military arms control. SDI refers to the proposed missile-defense program (the Strategic Defense Initiative) rather than reducing stockpiles. Environmentalism concerns ecological and policy movements, not nuclear disarmament.

So the SALT talks are the correct reference to efforts to limit nuclear warheads and missiles between the U.S. and the Soviet Union.
