TL;DR

The fifty‑year anniversary of Hiroshima and Nagasaki highlights that nuclear weapons have not been used since 1945, yet the reasons for this enduring non‑use remain poorly understood and the conventional deterrence explanation is likely incomplete. The article seeks to show that a normative prohibition, rather than mere deterrence, explains the sustained non‑use of nuclear weapons, focusing on the United States' experience. The authors argue that a developing global norm stigmatizes nuclear weapons as unacceptable, forming a normative prohibition that underpins the sustained non‑use.

Abstract

We have recently witnessed the fiftieth anniversary of the bombing of Hiroshima and Nagasaki, the only use of nuclear weapons in warfare. The non-use of nuclear weapons since then remains the single most important phenomenon of the nuclear age. Yet we still lack a full understanding of how this tradition arose and is maintained and of its prospects for the future. The widely cited explanation is deterrence, but this account is either wrong or incomplete. Although an element of sheer luck no doubt has played a part in this fortuitous outcome, this article argues that a normative element must be taken into account in explaining why nuclear weapons have not been used since 1945. A normative prohibition on nuclear use has developed in the global system, which, although not (yet) a fully robust norm, has stigmatized nuclear weapons as unacceptable weapons of mass destruction. Without this normative stigma, there might have been more “use.” This article examines this phenomenon in the context of the nuclear experience of the United States.
