The arms control system built during and after the Cold War is under enormous stress and is fraying at the edges. It once enabled significant improvements in international security but is in danger of not withstanding the resurgence of tensions in recent years. Urgent action is now needed to prevent the proliferation of nuclear, chemical, and biological weapons, as well as cluster bombs and anti-personnel mines.

Historically, technological change has altered how battles are fought but has not overturned the fundamental principles of war. However, three considerations may now represent an actual revolution: the recourse to tactical nuclear weapons, the development of software for “multi-domain operations,” and the prospect of general artificial intelligence. The organization of militaries and the use of force need to be rethought in this light.

Founded in 1936 and published by the French Institute of International Relations (Ifri), Politique étrangère, France’s longest-running journal of international relations, is set to publish a special issue in early June 2026. Bringing together distinguished French and international contributors, this issue aims to provide an overview of an uncertain world and its possible futures. In an unprecedented undertaking, Politique étrangère brings together a wide range of international contributions in an effort to grasp a global landscape that is at once open and fragmented, in all its diversity and dynamism. Through in-depth analyses of cross-cutting challenges, reflections on methods and structures of governance, and projections into futures feared or envisioned by creators from around the world—ranging from alternative histories to speculative thought experiments—the various approaches complement and challenge one another, opening up broad avenues for reflection.

It is tempting to conclude that international law’s influence is receding in a context where power struggles are in the ascendant, especially between dominant nations. But the law still carries weight: as the ultimate constraint on the use of violence, as a shared language for all human communities, and as a framework for action for those who seek to invoke it. It doubtless needs to be rethought and adapted to changes in international relationships, but without losing sight of its day-to-day importance.

Few countries have been as profoundly affected by the attacks of October 7th and the subsequent Gaza war as Germany. This is not merely a political controversy. It reflects a deeper structural problem: German-Israel policy has long rested on two guiding principles—a particular historical responsibility toward Israel derived from the Holocaust, and a firm commitment to universalist norms, above all international law and human rights.

Geopolitical risk has established itself, within the space of a few years, as a central variable in corporate strategy.
