Mutual Reinforcement: CSDP and NATO in the Face of Rising Challenges
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.
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.

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.

French Forward Deterrence: What Is in It for the Baltic States?
For what may be its most significant stress test since the end of the Cold War, European deterrence is under strain. Russia’s war against Ukraine has demonstrated Moscow’s willingness to use force and its ability to combine conventional operations with nuclear signalling, coercive rhetoric, and hybrid actions. At the same time, the gradual deterioration of transatlantic relations has revived concerns about the reliability of extended deterrence.
Europe at the Crossroads of DefTech: Rethinking the European Defense Innovation Ecosystem
“The way I look at Iron Dome is as the ultimate manifestation of the future of the United States’ role in future conflicts, which is not to be the world police, but to be the world gun store,” said Palmer Luckey in November 2023. Luckey is the founder of Anduril, one of the most prominent DefTech companies. The ambition is clear: to participate in global rearmament by capitalizing on the quality of American innovations and to dominate the arms market—at least in the West—through technological mastery.
