New Phases of Nuclear Arms Control and Disarmament [in Japanese]
Summary On July 31, 2023, Diplomacy published a paper by Professor Nobumasa Akiyama, dean of the School of International and Public Policy, titled "New Phases of Nuclear Arms Control and Disarmament." This paper examines the analysis of the components of a new structural calculation for arms control regimes necessary for inter-state disarmament and discusses methods to establish a foundation for nuclear disarmament as a consequence. Professor Akiyama pointed out that the objectives of relevant countries and the principles that sustained the arms control regime constructed during the Cold War era are no longer functioning sufficiently. As a cause, he argued that a minimal alignment of views among the parties involved in the arms control regime's political relationships, specifically, a divergence in views regarding guardrails, has emerged. Furthermore, he explained that the rise of China has increased the complexity of rebuilding arms control regimes due to China's technical and quantitative arms expansion and the opacity of its strategic capabilities related to armaments. In light of these issues, Professor Akiyama stated the necessity for integrated arms control to resolve differences in fundamental views on inter-state nuclear policies and to manage crises by combining diplomacy and economics.
