FIRST PRIZE Hypersonic Myths and Strategic Realities

Abstract

After decades of deterrence preventing nuclear war, hypersonic weapons appear poised to undermine strategic stability due to their speed, manoeuvrability, and potential ability to defeat missile defences. Because of their technological characteristics, Canadian and American discourse largely conclude that they will pose challenges to the international security environment, especially nuclear deterrence. However, the literature’s technical lens provides exaggerated threat assessments that assert hypersonics could disrupt the strategic nuclear balance, without acknowledging the risk of retaliation. Consequently, this paper counters these claims by drawing from Thomas Schelling’s emphasis on mutual vulnerability, and Kenneth Waltz’s insights about counterforce limitations, to demonstrate that hypersonic weapons cannot undermine strategic stability because they are subject to the same constraints that discourage a nuclear attack. It also argues that attacking command-and-control is more dangerous than attempting a counterforce strike, since it does not attempt to physically neutralize a second-strike capability.
