Modelling Nuclear Weapons Use


29 January 2022

Dear Network Members and Colleagues,

This week we present our report on nuclear weapons use cases in Northeast Asia, a video interview on confidence-building measures with Feroz Khan, a column by John Carlson on how to make the Comprehensive Test Ban Treaty permanent, and member activities.

On 28 January, APLN published the report “Reducing the Risk of Nuclear Weapon Use in Northeast Asia.” The report develops set of 25 use cases where nuclear weapons are used in relation to a Korean conflict or in a conflict in Northeast Asia in 2025-2030. The use cases involve (mostly) limited nuclear war involving the DPRK, US, China, and Russia as one or more of the states to use nuclear weapons first.The uses cases span the continuum from unintended to intended or deliberate use and consider the following elements: “Triggering Events and First Use”, “How the Conflict Evolves”, Use Case Consequences”, and “Use Case Uncertainties, Ultimate Outcome, and Policy Lessons”.

The report is the culmination of the first year of a three-year joint project with the Research Center for Nuclear Weapons Abolition, Nagasaki University (RECNA), and the Nautilus Institute. In the project’s second year, computer simulations based on the nuclear use cases will be developed and detailed policy recommendations will follow in year three.

The interview is based on his recent report for APLN titled “Trilateral Strategic Confidence Building Measures in Southern Asia.”

This video and special report is a part of an APLN project on Weapons of Mass Destruction (WMD). In this project, experts and APLN members assess key features of WMD infrastructure, force structures, capabilities, envisioned uses and solutions across the Asia-Pacific WMD landscape.

Making Ban on Nuclear Weapon Tests Permanent

On 26 January, in the latest APLN-Korea Times column, John Carlson, APLN senior associate fellow and former Director General of the Australian Safeguards and Non-Proliferation Office, argues that US ratification of the Comprehensive Test Ban Treaty is the key to lead others to ratify and bring the treaty into force.
