The U.S. nuclear weapon capability is intended to do which of the following?

• A. Ensure nuclear non-proliferation and protect our allies
• B. Deter conventional aggression only
• C. Have no impact on international security
• D. Limit deterrence to strategic triad only

Answer: (A)

Credible deterrence with alliance assurance is what a nuclear capability is designed to provide. By maintaining a credible and survivable nuclear option, the United States signals to potential adversaries that aggression against the U.S. or its allies would carry unacceptable costs. That credibility helps deter not only nuclear threats but also coercive actions more broadly, contributing to international stability. At the same time, extended deterrence reassures allies who rely on U.S. security guarantees, reducing their perceived need to develop their own nuclear weapons. When allies feel protected, wider proliferation pressures ease, supporting non-proliferation goals overall. The other ideas don’t fit because deterrence isn’t limited to deterring only conventional aggression, and nuclear forces do more than just influence one domain of conflict. Nuclear capability clearly affects international security and strategic stability, not none. And deterrence isn’t restricted to the delivery platforms of a strategic triad—the triad is part of how deterrence is implemented, but the purpose remains broader: to deter aggression and reassure allies, thereby supporting non-proliferation.
