In what scenario is the U.S. likely to use nuclear weapons?

The likelihood of the U.S. using nuclear weapons is primarily framed within the context of their use as a last resort if absolutely necessary. This approach is deeply tied to the doctrine of deterrence, which asserts that the threat of nuclear retaliation is meant to discourage adversaries from launching an attack. In this view, nuclear weapons are not intended for routine military operations or as tools of intimidation but are preserved for extreme scenarios where national survival is at stake, such as a significant attack on U.S. forces or allies.

The doctrine emphasizes careful consideration before employing such devastating weapons, reserving their use for moments when all other options have been exhausted and when the security of the nation is profoundly threatened. This strategic restraint reflects an understanding of the catastrophic consequences that would arise from nuclear engagement, aligning with international norms and policies aimed at nuclear non-proliferation and the prevention of nuclear war. Thus, the stance of using nuclear weapons only as a last resort underscores a commitment to minimizing risks while still maintaining a credible deterrent capability.
