Multilateral arms control, disarmament and non-proliferation

We aim to bolster the multilateral non-proliferation and disarmament regimes, particularly the nuclear Non-Proliferation Treaty. We provide ideas, analysis and research resources that support the efforts of serving diplomats in the NPT process. We also focus on specific regional challenges to the multilateral non-proliferation and disarmament system, including the future of nuclear diplomacy with Iran, and (in partnership with our sister Asia-Pacific Leadership Network) understanding Indo-Pacific perspectives on strategic risks. The ELN’s work has supported the P5 Dialogue, with a view to encouraging the NPT nuclear weapon states to engage jointly in strategic risk reduction. We also work to support the CTBT and encourage its entry into force and want to deepen the understanding of the concept of irreversibility in nuclear disarmament.

The unintended consequences of deterring cyber attacks through nuclear weapons and international law

Using nuclear deterrence to prevent cyber attacks presents not only ethical and strategic challenges but also significant legal concerns. International law imposes strict limits on the use of force, making a nuclear response to cyber attacks highly questionable. Attribution remains difficult, escalation risks are high, and proportionality concerns persist. YGLN member Verena Jackson writes that a more effective approach would focus on strengthening international norms, improving attribution mechanisms, and—above all—prioritising cyber resilience over expanding nuclear deterrence.

The CTBT: A success story and keystone for reinforcing the NPT regime ahead of the next 2026 NPT Review Conference

Despite not yet entering into force, the CTBT has seen some remarkable successes in establishing a global norm against nuclear testing and a robust verification system. However, rising geopolitical tensions underscore the urgent need for full ratification. Eleonora Neri of the Younger Generation Leaders Network (YGLN) argues for states to redouble efforts to universalise the Treaty and reinforce global non-proliferation commitments.

In Russia’s perceived war with the West, arms control is collateral damage

Three years into Russia’s full-scale invasion of Ukraine, and as New START enters its penultimate year in force, Nicholas Lokker writes that Russia is seeking to extricate itself from previously established arms control agreements it perceives as elements of the broader Western-dominated political and security order that it aims to overturn. He also argues that whilst Russia is unwilling to return to the negotiating table now, economics and external pressure from allies could herald a resumption of talks in future.

Stop the bleeding: How to protect existing NPT disarmament agreements and commitments

Steps to protect the Article 6 acquis on nuclear disarmament are a necessary condition for success of the 2026 NPT RevCon, but there is uncertainty under what political circumstances states parties will convene in 2026. As the nuclear disarmament acquis is currently threatened from many directions, this policy brief considers what steps states parties may take to protect the NPT under different scenarios.

Taking responsibility: How NPT members can support justice for victims of nuclear weapons – and through this, the NPT

This week, the Japanese organisation Nihon Hidankyo, founded by atomic bomb survivors (Hibakusha), will receive the 2024 Nobel Peace Prize demonstrating an increased international interest in past and ongoing harm caused by nuclear weapons. While the NPT largely remains silent on the humanitarian and environmental consequences of nuclear weapons and the associated legacies of the nuclear past, Jana Baldus and Caroline Fehl write that NPT members can do more to further the cause of nuclear justice, and that doing so is in their own best interest.

The politics of nuclear disarmament verification: How to advance nuclear disarmament

Following the UN Committee on Disarmament and International Security’s call to ascertain the views of Member States on the establishment of a Group of Scientific and Technical Experts (GSTE) on Nuclear Disarmament Verification (NDV), ELN Senior Network member Michael Biontino argues that NDV, beyond its technical aspects, is an essential political element of nuclear disarmament since it builds the trust needed for disarmament agreements. In the commentary, he outlines the various ways that NDV can advance the political processes necessary for effective disarmament.
