Opérations de déception. Repenser la ruse au XXIe siècle
Deception operations, which refer to manoeuver, economy of armed forces and surprise, need to be reintegrated at the center of strategy to respond efficiently to modern threats.
Often associated with cunning and stratagems, deception operations are as old as warfare while frequently neglected, whether at the strategic, tactical, or operational levels. Its main methods are concealment, simulation and intoxication, all of which help to deceive the enemy and make him believe in an illusion aimed at causing his loss. Despite an effectiveness proven many times in history, this practice is not without its dilemmas-cultural and ethical, but also in terms of resources allocation. As modern armed forces witness the constant progress of information networks, digitalization and artificial intelligence, new technologies seem to provide a fertile ground for a renewal of deception operations. If well used, these would help mitigate the end of the operational comfort predicted to Western forces and avoid the advent of a new tactical blockage.

Saudi Arabia’s Nuclear Temptations. Lessons Learned from Regional Instability
Saudi Arabia’s integration in the international arena and regional stability, notably through reducing its dependence on fossil energies, are crucial elements for the success of the Kingdom’s Vision 2030, the Crown Prince’s top priority. However, Mohammed bin Salman’s declarations in 2018 and 2021, indicating that “if Iran develops a nuclear bomb, we will follow suit as soon as possible”, combined with the recent strikes on key Iranian nuclear facilities, do not bode well for the future of the Kingdom, the region and the non-proliferation regime at large.
The Future of Air Superiority. Command of the Air in High Intensity Warfare
Air superiority, understood as control of the air, is a cornerstone of the Western art of warfare. It is a decisive condition, albeit not sufficient by itself, to achieve military victory, as it enables the concentration of air power toward the achievement of wider strategic objectives and protects other components from unbearable attrition levels. It is best achieved through the offensive use of air power in a joint effort to neutralize the enemy’s air power.
Europe Uncovered?
As Russia continues to threaten Europe, the Trump administration is making no secret of its desire to withdraw—at least partially—from the defense of the Old
Continent in order to focus on strategic competition with China. It is thus putting pressure on its European allies to increase their investment in the military sector. The NATO Summit in The Hague in June 2025 resulted in ambitious commitments by member states to increase their defense spending.
How should Britain and France cooperate to realise the Northwood Declaration?

The Northwood Declaration highlights that while both countries’ nuclear arsenals remain sovereign, cooperation on nuclear deterrence can ‘contribute significantly’ to the security of the North Atlantic Treaty Organisation (NATO) and the Euro-Atlantic region.
