Religion, Moral Order, and the Resacralization of International Politics
The question of the role of beliefs in international politics extends beyond that of religion alone. To an ever-increasing extent, the world is structured by competing normative projects, rather than straightforward civilizational blocs. With liberal universalism in retreat, religious traditions offer narratives, legitimacy, and international networks that support alternative visions of moral order, making the global system more pluralistic but also more unstable.
For much of the late 20th century, it seemed reasonable to assume that religion was gradually receding from the center of international politics. Modernization theory anticipated a process of secularization and the experience of Western Europe in particular appeared to confirm that trajectory. As levels of religious affiliation and participation declined in parts of the North Atlantic world, it became easier to imagine that economic development, urbanization, and liberal democratic governance would progressively relocate religion to the private sphere. After the Cold War, this assumption was reinforced by a broader narrative of convergence: ideological rivalry had ended, and liberal democracy appeared not only institutionally durable but normatively ascendant.
Three decades later, that confidence looks overstated. Religious language is now woven into political discourse across a wide range of contexts. Russian officials frame aspects of their foreign policy in explicitly civilizational terms linked to Orthodoxy. Indian political rhetoric increasingly invokes a civilizational understanding of the state. In the Middle East, religious authority remains intertwined with regional alignments. In multilateral forums, debates over gender, religious freedom, and cultural sovereignty routinely draw on explicitly moral and, at times, theological arguments. These developments are not confined to one region or one religious tradition. They cut across political systems and geographic boundaries.
It would be tempting to describe this shift simply as a “return of religion”. Yet such language obscures as much as it reveals. Religion never disappeared from international politics. Religious institutions, actors, and narratives have long shaped transnational activism, humanitarian engagement, conflict dynamics, and state legitimacy. What has changed is less the presence of religion than the status of the liberal normative framework within which it operated for several decades. [...]

Religion, Moral Order, and the Resacralization of International Politics
On (New) War
Are the new dynamics of power assertion, the redistribution of influence, and the emergence of new technologies changing both the place of war in the everyday life of our societies and the way war is waged when it occurs? Does the obsession with conflict, combined with technical efficiency, impose upon us a state of permanent latent war? And when weapons speak, does the involvement of modern technologies and the companies that produce them revolutionize both the political decision-making process and the way people are engaged in war? These are fundamental questions raised by the conflicts in Ukraine and the Middle East, and they are already shaping current thinking on military strategy and organization.

War and Technology: An Approaching Military Revolution?
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.
