Jay Tilden 2: The Myth of the Missile Gap, Rethinking Nuclear Deterrence
Are perceived gaps in nuclear capabilities driving unnecessary fears of a new arms race? In this Part 2, Jay Tilden examines one of the most enduring questions in deterrence theory: How do perceptions of vulnerability influence nuclear strategy and global stability? Drawing on history, policy, and strategic theory, Tilden explores the concept of the “missile gap,” the political and psychological forces that shape deterrence debates, and whether symmetrical nuclear capabilities can actually contribute to stability rather than instability. The discussion challenges common assumptions about nuclear competition, emphasizing that deterrence depends as much on communication, understanding, and credibility as it does on military capability. The conversation also examines adversary motivations, the role of nuclear doctrine, and the risks of public misunderstandings surrounding nuclear weapons and strategy. Tilden argues that calls for new capabilities are often driven by perceived vulnerabilities rather than actual strategic disadvantages, while highlighting the importance of informed, transparent dialogue among policymakers, military leaders, and the public. Key Takeaways: Perceived vulnerabilities often drive nuclear escalation and modernization efforts. Nuclear responses do not always need to be proportional to be credible. Strategic dialogue and communication are essential to maintaining deterrence stability. Symmetry in capabilities can be stabilizing rather than destabilizing. Arms races may reflect mutual recognition of strength and capability, not necessarily increased instability.
