Three and a half years before the scheduled entry into force of the European regulation ReFuelEU Aviation (RFEUA), which requires aviation fuel suppliers at Union airports to offer a sustainable synthetic alternative (e-SAF), no sizeable commercial production unit (greater than 10,000 tons per year) is active within Europe yet, nor has it even passed the Final Investment Decision (FID). Is a major step in the European Union (EU) plans for decarbonizing air transport at risk of not happening, or at least being postponed for several years? Is Europe losing its bet to create a market for e-SAF? Under what conditions can this bet still be won? Could sovereignty and energy security preoccupations unlock necessary public support and help to overcome economic, financial, logistical or administrative obstacles?

Paris has come a long way in its approach to enlarging the European Union. However, French support remains fragile, due in part to a lack of public support.

The European biomethane sector is at a critical juncture.

Armenia’s June 7, 2026, parliamentary election is shaping up less as a routine vote than as a referendum on Nikol Pashinyan’s post-2020 course, which includes peace with neighbors, reduced dependence on Russia, and a more explicit European orientation. The ruling Civil Contract party is still the frontrunner, but its position is fragile, as the campaign is being fought in a highly polarized environment shaped by the trauma of defeat in the war against Azerbaijan, the displacement of Karabakh Armenians, and the massive election interference from Russia.

This study analyzes a significant transformation in NATO’s practical support to Ukraine, marked by the establishment of the NATO Security Assistance and Training for Ukraine (NSATU) mission and the Prioritized Ukraine Requirements List (PURL) funding mechanism.

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.

The system that emerged after the Second World War to regulate international relations is now moribund. Russia and China may have weakened it, but it seems that Donald Trump’s United States may deliver the fatal blow. The prevailing atmosphere is one of power struggles, and the rise of nationalisms is fraught with danger. The artificial intelligence revolution also needs to be factored into this equation, as it has a strong bearing on how much power different players can exert. In this respect, Europe must ensure it does not get left behind.

The construction of the European Union is historically inseparable from the emergence, at the end of World War II, of an Atlantic world dominated by the United States. Successive enlargements and the revision of U.S. policy are undermining the concepts upon which the European Union has been built since the fall of the USSR. It is undoubtedly time to return to a path of more diverse groupings, corresponding to the levels of commitment and the interests of the states of the Old Continent.
