Security & Defense

We are now in the fifth week since the U.S. airstrike that killed top leaders of the Iranian regime, initiating a war involving the United States and Israel against the country. More than a month of mutual bombardments between Iran and Israel has ensued, extending to other Persian Gulf nations, U.S. military installations—and even Cyprus. From a global perspective, the impact has stemmed primarily from disruptions to regional production of goods and the blockade of the Strait of Hor ...

This essay examines the establishment of the Board of Peace as a test case in contemporary peace governance and hegemonic experimentation. While the Board, politically activated in early 2026 and formally anchored in a resolution of the United Nations Security Council, benefits from derivative legality under the UN Charter, its legal foundation remains constitutionally fragile, its mandate ambiguously constrained, and its accountability architecture underdeveloped, notwithstand ...

Sous Trump II, la conflictualité s’affirme moins comme un simple effet de la polarisation partisane que comme un principe d’organisation de l’exercice du pouvoir. À partir des prises de parole présidentielles, ce Papier montre comment des enjeux distincts, tels que l’immigration, la fraude, la sécurité, les controverses culturelles ou les rivalités internationales, sont intégrés dans une même architecture discursive orientée vers la restauration de l’ordre. La conflictualité y appar ...

Les conflits armés ont toujours des coûts économiques exorbitants, sans parler des pertes humaines. Le coût de la guerre est difficilement chiffrable.  Il dépend de la durée de l'enlisement et des « à-côtés ».  En fait, les conséquences économiques, tout comme les causes des conflits armés sont toujours complexes à appréhender. Les risques liés aux conflits génèrent de nombreuses incertitudes économiques, directement perceptibles dans les contraintes budgétaires, ...

Divergent regulatory regimes for data, driven by different motivations, ranging from privacy protection in the European Union to information control in China, could eventually produce distinctively different, and possibly contradictory, bodies of data. Artificial-intelligence models trained on those datasets could produce differing and possibly even conflicting outputs. To the extent that AI outputs start to shape human perception and to influence decisions, in governments and ...

L’arrestation du président vénézuélien Nicolàs Maduro a suscité la sidération internationale en interrogeant sur le respect du droit international ; puis, fort logiquement, cette opération a conduit à maintes analyses tant sur les arguments politiques, sécuritaires et géostratégiques avancés par Washington que sur les ambitions sous-jacentes ayant présidé à cette décision sans réel précédent dans l’histoire récente. Outre la lutte contre le narcotrafic, c’est bien évidemment la ...

From the use of tariffs as a foreign policy instrument, to the weaponization of critical resources, and from targeted sanctions to attacks on critical infrastructure, economic security is at the forefront of international debates. The aggressive use of economic instruments for strategic purposes has become an explicit feature of international affairs, in a way not seen since the interwar period[1]. Beyond the weaponization of resources of all kinds, an increasing ‘monetization’ is u ...

Le Mali, le Burkina Faso et le Niger, réunis au sein de l’Alliance des États du Sahel (AES), affirment l’ambition de bâtir une souveraineté nationale qui leur permettrait de s’émanciper de la domination et des influences extérieures et de se doter d’une liberté d’action dans les choix de développement politique et économique. Cependant, cette ambition se heurte à de nombreuses contraintes économiques et sécuritaires.La souveraineté ne peut se construire sans une base économique soli ...

La création de l’Alliance des États du Sahel (AES) symbolise une rupture politique et géostratégique majeure, appuyée sur un discours souverainiste et anti-occidental. Deux ans après, Mali, Burkina Faso et Niger peinent à assurer leur intégrité territoriale, à stabiliser leur sécurité intérieure et à bâtir une gouvernance solide. L’intégrité territoriale est un problème commun aux trois États, car dans ces pays, la cohésion de l’État et le contrôle du territoire sont directement men ...

Fuel access has become a strategic pressure point across Mali and its neighbors. In 2025, Jama’t Nusrat al Islam wal- Muslimeen (JNIM) shifted from sporadic interdictions to a deliberate fuel-blockade strategy intended to pressure Bamako without holding territory. By selectively constraining movement along the Sikasso–Kayes–Bamako corridor, the group turned fuel scarcity into a tool of coercion, governance, and narrative control—shaping behavior in the capital while remaining largel ...

The member countries of the Alliance of Sahel States, Mali, Burkina Faso, and Niger, remain dependent on a limited number of maritime access corridors, a configuration that constrains their adjustment capacity in the event of disruption and heightens the vulnerability of their supply chains. The Jama’at Nusrat al-Islam wa al-Muslimin (JNIM) blockade of the Kayes-Nioro area revealed how critical the Dakar-Bamako corridor is for the political and economic stability of Mali. Its interr ...

Les pays membres de l’Alliance des États du Sahel (le Mali, le Burkina Faso et le Niger) demeurent dépendants d’un nombre restreint de corridors d’accès à la mer, une configuration qui limite leur capacité d’ajustement en cas de perturbation et accroît la sensibilité de leurs chaînes d’approvisionnement. Le blocus du tronçon Kayes-Nioro a illustré la forte criticité du corridor Dakar-Bamako : l’interruption d’un segment unique a entraîné une contraction rapide des flux, révélant la ...

The U.S. military buildup in the Caribbean—the most significant since the Cuban Missile Crisis—comes at a moment when a new world order is taking shape, its contours still unclear, and in which the U.S. seeks to be more assertive in the Western Hemisphere. This disposition toward South America and the Caribbean was underscored by the recent publication of the new U.S. National Security Strategy, in which the Monroe Doctrine is explicitly invoked. This Policy Brief situates the devel ...

The return of President Donald Trump to the White House at the start of 2025 was expected to signal an American retreat from international engagement, especially in regions of traditional security interest, such as southern Europe, North Africa, and the Middle East. To the surprise of many observers around the Mediterranean, and perhaps to the dismay of some in the Trump administration’s ideological orbit, this has not happened. If anything, the second half of 2025 has seen a high d ...

I recently participated in a discussion between Israelis and Arabs, some living in the Middle East, some living abroad[1]. The discussion topic was ‘The Two State Solution’. This article presents my personal takeaways from the discussion. It does not try to describe the details, and other participants may have different takeaways.I joined the discussion thinking that the two-state solution was dead. Most of the other participants felt the same way—all very pessimistic. But I left fe ...

An unusual gesture indeed—the dictator, more often than not a recluse, withdrawn behind his fortress and protected by 1.2 million armed soldiers, finally admitted what had long been seen on the battlefield in Ukraine and by spy satellites far above. North Korean soldiers—possibly 12,000 of them—are fighting on front lines alongside Russian troops, and they are falling or being wounded; some 4,000 men so far, by current estimates.  ...

In 2025, the global landscape became increasingly fragmented and uncertain. Great power competition intensified, regional conflicts became protracted and exacerbated, while economic nationalism reshaped the rules of trade and development. The mechanisms for conflict resolution and cooperation that have long provided a foundation for international cooperation are now under strain due to polarization and mistrust. Even longstanding alliances, bilateral and collective security architec ...
