Confronted with a U.S. disengagement and the Russian threat, Europeans are reconsidering their stance on nuclear deterrence. Given the capabilities of the French and British arsenals, can Europe develop an independent nuclear deterrent?

Forget the fantasy of a Eurobomb or a travelling nuclear suitcase between EU capitals. The real question is how to better leverage the existing arsenals of France and the UK in a Europe where Washington’s commitment is no longer a given. What happens if NATO allies can’t trust that the United States will trade Boston for Berlin?

The answer is not to mimic the American model with tactical nukes scattered across the continent. If Paris and London were to extend deterrence, it would be because their national security is inextricably tied to Europe’s stability. Any adaptation must reflect this.

For France, that could mean clarifying its vital interests and going beyond presidential speeches that require explaining to be correctly understood by allies—but without sharing nuclear decisionmaking or stationing warheads abroad. Those are currently a no-go for Paris. Conventional forces, missile defense, and deep precision strikes must also be part of the equation. Instead of obsessing over warhead numbers, why not start by reinforcing French deployments on NATO’s Eastern flank?

Even though the UK considers it already participates in European security through its nuclear contributions to NATO, London must American-proof its long-term nuclear future in case of diminished cooperation with the United States.

The time for pragmatic nuclear dialogue and political commitments is now.

Heir to a tradition dating back to the founding of Ifri, the Security Studies Center provides public and private decision-makers as well as the general public with the keys to understanding power relations and contemporary modes of conflict as well as those to come. Through its positioning at the juncture of politics and operations, the credibility of its civil-military team and the wide distribution of its publications in French and English, the Center for Security Studies constitutes in the French landscape of think tanks a unique center of research and influence on the national and international defense debate.

The conflicts in Europe, Asia and the Middle East demonstrate a return of nuclear power to the balance of power. Arsenals are being modernized and expanded, while arms control is collapsing. This research program aims to analyze these phenomena.

Framework Nation: A European Challenge and French Ambition

Date de publication
10 June 2026
Accroche

First appearing in the early 2000s, the framework nation concept follows several distinct rationales, whether it refers to a country assuming the leadership of a military operation, directing a multinational capability project, or commanding a permanent force structure. In every case, the country that takes on this role fully intends to derive from it additional politico-military influence.

The Nuanced Relationship Between Public Opinion and Foreign Policy

Date de publication
23 July 2026
Accroche

Public sentiment is something decision-makers must contend with, especially in democratic states. However, the extent to which public opinion shapes foreign policy varies. Three Council of Councils experts in France, India, and Nigeria reflect on how public opinion does—and sometimes does not—affect foreign policy decisions.

Over the past ten years, NATO has held almost as many summits as it did during the entirety of the Cold War. Are they still useful, or is it time to stop holding annual meetings?

How does France’s nuclear deterrent contribute to the defense of Europe?

Date de publication
10 July 2026
Accroche

France’s nuclear deterrent, serving first and foremost to defend France’s vital interests, also contributes to the defense of Europe. This contribution has been recognized within the North Atlantic Alliance since 1974, but remains little known. In a speech closely followed by France’s European partners and its adversaries alike, President Emmanuel Macron announced a new concept for French nuclear deterrence: “forward deterrence” (dissuasion avancée). This article aims to explain the origins of this concept, outline its main pillars, and describe the partnerships that are sought. It then discusses the relationship with the U.S. doctrine of “extended deterrence”, and finally offers some ethical considerations.
