Which statement best describes one stated purpose of the U.S. nuclear weapon capability?

• A. Achieve global dominance
• B. Reduce alliance commitments
• C. Ensure nuclear non-proliferation and protect our allies
• D. Promote arms race

Answer: (C)

The main idea being tested is how nuclear capability supports deterrence and alliance protection, reinforcing stability and nonproliferation through credible security assurances. The statement about ensuring nuclear nonproliferation and protecting our allies best captures this role. A credible nuclear deterrent helps deter aggression against the U.S. and its partners, making potential adversaries think twice before acting. It also reassures allies that they are safeguarded, reducing their perceived need to seek their own nuclear weapons and helping prevent a broader arms race. This combination—deterrence plus alliance protection—supports nonproliferation goals and regional stability. The other options describe outcomes that would undermine stability or contradict established nonproliferation and alliance strategies: global dominance would trigger counterbalances and instability, reducing alliance commitments would weaken deterrence, and promoting an arms race would exacerbate proliferation pressures.
