From Burden Sharing to Burden Transfer: U.S. Demands on European Conventional Defence
How U.S. strategic guidance and official statements translate burden-sharing into operational and capability expectations for European allies
The text consolidates a coherent U.S. signalling pattern during 2025–26 in which Europe’s conventional defence is explicitly framed as primarily a European obligation, with the United States positioning itself as a critical but more limited enabler. The core logic is presented as a rebalancing of alliance labour: European allies are expected to generate the preponderance of conventional forces required for deterrence and, if necessary, high-intensity defence in Europe, while the United States sustains extended nuclear deterrence and selectively contributes conventional capabilities, with increasing emphasis on the Indo-Pacific. Within that frame, U.S. documents and senior officials repeatedly stress an “inputs to outputs” discipline, treating higher defence spending as necessary but insufficient unless it produces ready forces, usable munitions, resilient logistics, integrated command structures, and expanded defence-industrial capacity, with compliance assessed through observable capability delivery rather than declaratory intent.
