Constrained Sovereignty: Europe Reshapes Its Defence Under Russian and American Pressure

This month's dynamic can be summed up in a single sentence: under pressure from a Russia whose growing tolerance for risk is described by Allied officials, European capitals are replacing multilateral cooperation with sovereign or bilateral responses, while Washington turns its support for Kyiv into a negotiating lever. The transatlantic security architecture is not unravelling, but it is being reshaped around national trade-offs that are shifting the centre of gravity of industrial and operational decisions.

This shift matters now because it is playing out simultaneously across three mutually reinforcing fronts: the legal threshold of collective defence, being stress-tested by hybrid warfare; the supply chain for support to Ukraine, now sensitive to Washington's mood swings; and the major capability programmes, the most spectacular failure of which is pushing France to go it alone. For an industry leader, the question is no longer whether cooperation exists, but on what terms and under which political constraints it continues.

A Collective-Defence Threshold Each Party Seeks to Define Before It Is Tested

The first fault line is as much legal as it is military. Several heads of European intelligence services and the Institute for the Study of War warn that Russia could test the application of Article 5 of the North Atlantic Treaty Organization within a few months (London Business News, 21/09 and 23/09), with Alliance officials attributing to the Russian president an increased tolerance for risk as the conflict becomes bogged down. The stakes are not abstract: they concern the boundary between sabotage, hybrid attack and outright aggression — a boundary Russia has every interest in keeping blurred.

Faced with this ambiguity, the European Union has chosen to dispel it through words. The European Commissioner for Defence explicitly stated that a Russian strike against a weapons factory on EU territory would constitute legitimate grounds for a NATO military response under Article 5. This doctrinal clarification responds to a documented threat: Estonian security services formally attributed to a Russian-sponsored sabotage operation the arson that targeted the military robotics company Milrem in August, prompting diplomatic measures from Tallinn. Hybrid warfare is now directly targeting the defence industrial base, which explains why Europeans are seeking to lock in, in advance, the threshold that triggers Allied solidarity.

Support for Kyiv, Caught Between American Leverage and European Initiatives

The second fault line pits the American instrumentalisation of support against the deepening of European support. Ukrainian officials lament that the Pentagon interrupted the sharing of certain key missile alerts and restricted Starlink connectivity — a retaliatory measure linked to repeated Ukrainian strikes on Russian energy infrastructure. Washington is therefore making its tactical intelligence conditional on Kyiv's operational conduct, introducing a structural uncertainty into the support chain. That Ukrainian forces nonetheless struck the Russian Azov Optical-Mechanical Plant on 26 September — a critical supplier of components for several Russian missile programmes — shows that this conditionality is not enough to curb Ukraine's freedom of action.

It is precisely in this space that European support is reorganising, more through technical capabilities than through raw volumes. Germany announced an aid package worth $1.1 billion, notably featuring drone interceptors. The Dutch firm Intelic is deploying its Nexus artificial-intelligence software, under a €30 million contract with the Netherlands Ministry of Defence, to unify Ukrainian drone systems, while Estonia's KrattWorks is designing a target drone mimicking Shaheds to train air defences. This technological upgrading, driven by small states and niche players, is shaping a form of support less dependent on major American flows and more firmly anchored in European innovation.

When the Failure of a Joint Programme Validates the Sovereign Logic

The third fault line is industrial, and it carries the heaviest consequences. Following the definitive abandonment of the pan-European FCAS project pursued with Germany and Spain, France has formalised its choice to develop its future combat aircraft (ACF) alone — a sovereign programme aimed at conventional entry into service by 2040. For Paris, the failure of the continent's most emblematic aerial cooperation validates national preference in the most strategic segments.

This retreat towards the sovereign or the bilateral is found elsewhere. Germany is consolidating its naval rearmament by securing Bundestag approval for the acquisition of four additional MEKO A-200 DEU anti-submarine frigates from ThyssenKrupp Marine Systems, bringing the future fleet to eight vessels after the cancellation of the F126 programme. In the United States, consolidation is benefiting a single player: Boeing has been selected both for the US Air Force's F-47 and for the US Navy's F/A-XX, while the Pentagon secured its production of SM-3 Block IB interceptors through a $6.3 billion, five-year agreement with Raytheon. On both sides of the Atlantic, capability reconstitution is proceeding on a narrower national basis rather than within shared architectures.

In Brief

• Britain's seizure of the Russian tanker Smyrtos in the English Channel on 14 June led to a reduced presence of Russia's shadow fleet in the Channel, forcing it to divert around northern Scotland.
• The Warsaw Security Forum on 14 October crystallised the doctrinal debate between attrition through autonomous drones and the maintenance of a mass of conventional heavy armour.
• The Baltic states and Poland, through statements by Donald Tusk, are maintaining pressure on their allies to anticipate Russian missile or drone strikes on NATO territory.

To Watch

• 5 October to 6 November: disarmament sessions and votes of the First Committee of the United Nations General Assembly in New York (Institutional agenda).
• 16 to 17 November: European Union Foreign Affairs Council (Defence) in Brussels, focused on strategic autonomy following the breakdown of FCAS (Institutional agenda).
• 16 to 20 November: seventh Review Conference of the Convention on Certain Conventional Weapons in Geneva, addressing the regulation of lethal autonomous weapons systems (Institutional agenda).
• 23 to 27 November: fourth session of the Open-Ended Working Group on the Prevention of an Arms Race in Outer Space in Geneva (Institutional agenda).
• 3 to 4 December: OSCE Ministerial Council in Lugano, on regional security and arms control (Institutional agenda).

Key Takeaways

• The European Commissioner for Defence asserts that a Russian strike against an EU weapons factory would justify a NATO response under Article 5.
• Washington is making its sharing of missile alerts and Starlink access conditional on Kyiv's operational conduct, weakening the support chain to Ukraine.
• Following the failure of FCAS, France is developing its future combat aircraft alone, confirming a sovereign retreat in the major European capability programmes.
