Why does the United States need a nuclear capability?

• A. It underpins all other elements of deterrence.
• B. It guarantees victory in any conflict.
• C. It eliminates the need for conventional forces.
• D. It ensures uncontested regional dominance.

Answer: (A)

Nuclear capability shapes deterrence by making the threat of retaliation credible and devastating enough that an adversary weighs the costs of aggression as unacceptable. This credibility is what allows deterrence to influence enemy calculations, because any attack would risk severe and unpredictable consequences. The strength of a nuclear force also supports allies through extended deterrence and provides strategic options in crises, helping to prevent miscalculation and manage tensions without immediate conflict. This isn’t about guaranteeing victory in every conflict, nor does it replace every conventional capability. Conventional forces remain essential for a wide range of operations, and nuclear weapons do not automatically grant regional dominance. So the best way to describe why a nuclear capability matters is that it underpins all other elements of deterrence.
