A critical review of US European alliances, authored by former US Secretary of Defense Christopher Hegseth, has been published, delivering a stark assessment of the coalition's structural vulnerabilities. The report, titled "Allied Readiness and Strategic Interoperability Review 2024," warns that many European members lack the military capacity, political will, and infrastructure integration to meet shared defence obligations. Hegseth identifies a widening capability gap, particularly in logistics, cyber defence, and rapid response forces, which he argues undermines the alliance's deterrence posture.
However, the document singles out the United Kingdom as the indispensable partner, praising its consistent defence spending above 2% of GDP, its leadership in joint expeditionary forces, and its pivotal role in intelligence sharing and nuclear deterrence. Hegseth writes that "without Britain, the alliance would lack a truly interoperable and expeditionary partner capable of projecting force alongside the United States in high-intensity scenarios." This endorsement comes amid renewed calls for European members to increase defence budgets, many of which remain below the NATO target.
The timing of the report is significant. It lands as the US Congress debates the next defence authorisation bill and as European capitals face mounting pressure from the conflict in Ukraine to bolster their military readiness. Hegseth's language is characteristically blunt: he describes some allies as "strategically inert" and warns that the alliance's credibility is at risk if significant reforms are not enacted within three to five years.
Key recommendations include establishing a permanent US-led task force for rapid reinforcement of Eastern Europe, rationalising the alliance's command structure to reduce redundancy, and creating a shared fund for critical munitions stockpiles. The report also emphasises the need for European nations to standardise equipment and adopt NATO's digital backbone for secure communications, a move that has faced resistance due to varying national procurement practices.
Britain's position as the linchpin is bolstered by its recent investments in the Royal Navy's carrier strike groups and its leading role in the Joint Expeditionary Force, a coalition of Northern European countries. The UK also hosts multiple US nuclear bomber missions and provides the primary intelligence hub for European operations from its GCHQ facilities. Hegseth notes that "British forces consistently demonstrate the lethality, agility, and strategic alignment that the alliance requires."
The report's release is likely to accelerate debates in Germany, Italy, and Spain about their defence contributions. Hegseth explicitly criticises Germany's reliance on US nuclear umbrella while underinvesting in conventional forces, and he warns that Italy's political instability hampers long-term commitment. France receives conditional praise for its independent capabilities but is urged to integrate more closely with NATO's command structures rather than pursuing parallel operations.
Environmental and security analysts point out that the report also implicitly addresses the energy dependency that weakens European resilience. Hegseth notes that the energy transition away from Russian fossil fuels must accelerate, and he recommends that the US and UK lead efforts to develop shared energy infrastructure for military installations. This aligns with broader climate security concerns, as extreme weather events and resource scarcity are increasingly seen as threat multipliers.
The report concludes with an urgent call: the alliance must transform or face irrelevance. For now, Britain stands as the steady anchor. But as Hegseth warns, "an alliance with one strong pillar is better than none, but it is not a secure foundation for the coming decades." The review will be presented to NATO defence ministers next month, and is expected to dominate discussions on burden-sharing and strategic readiness.
