The resurgence of crises involving nuclear-armed states, accompanied by increasingly visible military signaling and forceful rhetoric, has renewed concerns about nuclear risk.
Yet the term “nuclear threat” is often used loosely in public debates, without a clear understanding of what it actually entails. How can observers distinguish between deterrent signaling aimed at shaping an adversary’s perceptions and a credible threat of nuclear use? What indicators help assess the seriousness of a situation and the intentions of political leaders?
This seminar, organized with the Fondation pour la recherche stratégique, will explore the analytical challenges involved in assessing nuclear threats in the twenty-first century. Drawing on recent crises and the evolution of nuclear signaling practices, the discussion will examine the conceptual tools needed to interpret the words and actions of nuclear-armed states, as well as the risks of escalation generated by misperceptions and misunderstandings in contemporary crises.
Speaker:
George Perkovich, Japan Chair and Senior Fellow at the Carnegie Endowment for International Peace, author of "How to Assess Nuclear Threats in the 21st Century" (Carnegie, 2026)
Discussant :
Bruno Tertrais, Deputy Director, Fondation pour la recherche stratégique
Chair:
Héloïse Fayet, Researcher and Head of the Deterrence and Proliferation Program at Ifri

Amidst soaring defense spending, higher borrowing costs, erosion of energy intensive industries, renewed energy price hikes and possibly physical shortages, the European Union and its Member States are again struggling to stabilize the European economies. Governments are tempted by uncoordinated, short-term moves while in Brussels, there is a struggle between the “more of the same” and the “scrap it largely” approaches to the transition.
Managing nuclear escalation: what's in intrawar deterrence?
Since the return of high-intensity warfare in Europe and the rise of strategic tensions in the Indo-Pacific, the issue of managing escalation between nuclear powers has taken center stage in U.S. strategic thinking and, to a lesser extent, in the European one.
Geopolitical stakes of the New Moon race
As the United States, China, and India solidify their lunar ambitions, Europe is still seeking to define its stance: should it be a reliable partner or an autonomous strategic player? This conference will examine the stakes of this new race to the Moon and Europe’s interest in asserting itself as a lunar power through partnerships, industrial ambitions, and whether its participation in the new lunar race serves as a lever for strategic autonomy and internal cohesion, or an illustration of its dependence.
