Disarmament is Good, but What We Need Now is Arms Control

Abstract

This article aims to correct a number of misconceptions held by both scholars and activists about the United Nations Treaty on the Prohibition of Nuclear Weapons (TPNW), and international nuclear weapons law generally. It first reviews the development of international law related to nuclear weapons, and provides a novel taxonomy of legal obligations divided into three substantive categories. It then examines the TPNW within that taxonomy, and considers how it should be understood to fit within this legal context. It concludes that the TPNW is essentially a nuclear disarmament treaty. While it should be welcomed as a contribution to nuclear disarmament law, it should not be confused with nuclear arms control treaties, which are distinct in role and purpose. The article concludes that at the current moment of crisis in nuclear arms control law, a refocusing of attention is needed to conclude a successor treaty to New START, which is due to expire in 2026.
