Third or “Second and a Half”? Continuity, Path Dependence, and the Third Nuclear Age
Global Policy, Volume 16, Issue 5, Page 934-944, November 2025.ABSTRACT The world has entered a new nuclear age. Scholars have characterized this “third nuclear age” as one of renewed competition among nuclear‐armed great powers and the coming maturation of new technologies. I trace the origins of the new nuclear age. Focusing primarily on US strategies with two case studies on conventional strike capabilities and
