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.

For what may be its most significant stress test since the end of the Cold War, European deterrence is under strain. Russia’s war against Ukraine has demonstrated Moscow’s willingness to use force and its ability to combine conventional operations with nuclear signalling, coercive rhetoric, and hybrid actions. At the same time, the gradual deterioration of transatlantic relations has revived concerns about the reliability of extended deterrence.

Germany is facing fundamental challenges to its economic and social model and is seeking a new course. The German post-war model was hugely successful, leading to economic strength and prosperity over many decades, but now it is steadily faltering. The previously latent fear of deindustrialization is becoming more concrete, particularly due to the weakening of a key sector: the automotive industry.
