Contributor(s): Chris Gilson, Dr Lauren Sukin | In response to what the US sees as potential growing threats from China and North Korea, nuclear weapons are becoming a more and more important part of US alliance commitments and partnerships in East Asia. But what does this focus on nuclear weapons for both deterrence and reassurance mean for US foreign policy and for the security of the region? And could there be an alternative which puts a greater focus on conventional armed forces?

To discuss these topics, in June 2025 the Phelan US Centre spoke to Dr Lauren Sukin about her recent article, in the Journal for Peace and Nuclear Disarmament, with Samuel Seitz of MIT, “Deemphasizing Nuclear Weapons in Nuclear Deterrence: The Case for Conventional Counterforce”. Dr Sukin is Assistant Professor in LSE’s Department of International Relations and a Centre Affiliate at the LSE Phelan US Centre.
