Over the past five years, several political and security developments have made it increasingly necessary to look at European Union (EU) / North Atlantic Treaty Organization (NATO) relations through a different lens.

Corps analyses

The renewed emphasis on European strategic autonomy, a concept that lends itself to multiple and sometimes diverging interpretations, has been a cause for rising concern among NATO member states. While some of those concerns appear legitimate, there are many ways to increase Europe’s strategic autonomy without undermining the Alliance. As the EU and NATO have taken new steps to strengthen their cooperation over the past years, it appears more important than ever to reject false dichotomies when prioritizing efforts to strengthen European security, to look at opportunities to better coordinate EU and NATO capability development processes, and to identify which types of military capabilities European countries should invest in to make burden-sharing with the Alliance more effective.

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.

Accroche

Among all European countries, Finland is perhaps the one whose strategic culture and military model have changed the least since the end of the Cold War.

Stability under Pressure. A Pakistani View on Nuclear Deterrence after Pahalgam

Date de publication
24 June 2026
Accroche

The May 2025 India-Pakistan crisis after the Pahalgam attack has generated a familiar but incomplete debate: did nuclear deterrence work, or did it merely allow both sides to fight a limited war under the nuclear shadow? The better answer is that deterrence worked at the level at which it was designed to work. It prevented a general war and an uncontrolled vertical escalation, and kept nuclear weapons in the background. But it did not prevent India from attempting to carve out space for conventional action, nor did it prevent Pakistan from responding conventionally to restore deterrence credibility.
