Signal
Since Maastricht in 1992, the European Union has pursued deeper integration. Enlargement expanded markets and influence, but often without a shared foundation of state capacity. Borders remained inconsistently regulated, asylum rules fragmented, and external defence tethered to US and NATO guarantees. Integration was expected to generate cohesion. Instead, gaps in sovereignty infrastructure left the project exposed and amplified fractures inside the Union.
By the mid-2010s, pressures converged and pulled the project apart at its seams. The migration surge of 2015, Russian aggression in Ukraine, and enduring economic asymmetries across the Eurozone all revealed structural weaknesses. Citizens questioned whether EU institutions could secure borders, enforce common rules, or defend sovereignty. Civic trust weakened, and polarisation deepened across member states.
Why it matters
The failure to build full sovereignty infrastructure became visible across borders, enlargement, and defence. Border regimes remained uneven, producing a dissonance between supranational policy and popular expectation. Enlargement, often accelerated for geopolitical reasons, admitted states whose governance capacity was not fully aligned, diluting the cohesion of the bloc. Defence remained outsourced to NATO and United States guarantees, leaving Europe with integration in economics and regulation but dependency in existential security.
These gaps cut to the core of the project. They eroded citizens’ trust in supranational institutions and created vulnerabilities that external rivals readily exploited. Russia and other adversaries amplified weaknesses through disinformation, pressure on migration routes, and manipulation of debates on enlargement. Internally, decision-making slowed into rigidity as competing sovereignties pulled in different directions, exposing the gap between supranational ambition and democratic legitimacy.
Strategic takeaway
The Sixth Field frames the EU not as a failed ideal but as a case of unfinished sovereignty infrastructure. Cohesion requires visible, credible systems, not abstract rhetoric. Borders must be defended with consistent rules, accession standards must be enforced with credibility, and defence must rest on capacities Europe can claim as its own. Sovereignty infrastructure is not only external, it is also political. Institutions must be both effective and democratically legitimated to sustain civic trust.
At present, the European Commission wields vast regulatory and economic power without a direct electoral mandate. The European Parliament, while expanding in importance, remains fragmented, with electorates voting along national lines rather than European ones. The result is supranational authority robust in regulation but fragile in legitimacy. Without both secure sovereignty infrastructure and trusted institutions, European integration becomes contested terrain and civic trust, the hidden infrastructure of democracy, is what ultimately breaks if it is not reinforced.
Investor Implications
Defence primes and border-technology firms stand to gain as the EU shifts from regulatory to sovereign capacity-building. Leonardo (BIT: LDO), Thales (EPA: HO), and Airbus Defence (EPA: AIR) will benefit from investment in autonomous deterrence. Border-security and biometric specialists such as IDEMIA and Palantir (NYSE: PLTR) are well positioned for EU procurement tied to migration control. Investors should track enlargement-linked infrastructure projects particularly in Ukraine and the Western Balkans, which will drive capital into energy grids, digital corridors, and border systems. Civic-tech ventures that strengthen institutional legitimacy, such as digital identity providers and disinformation-monitoring platforms, may also draw EU funding as Brussels seeks to restore civic trust.
Watchpoints
2025 - 26 → Enlargement debates (Ukraine, Western Balkans): whether Brussels enforces stricter entry standards or repeats cycles of dilution.
2025 → NATO - EU defence cooperation summits: indicators of whether Europe commits to autonomous deterrence or remains dependent.
Tactical Lexicon - Battlefield Acceleration Loop
Sovereignty infrastructure is the system of defended borders, enforceable standards, credible defence capacity, and democratic legitimacy upon which political authority rests.
With such infrastructure, pluralism and shared governance can endure.
Without it, integration erodes civic trust and leaves institutions exposed to populist backlash, legitimacy crises, and external manipulation.
Europe’s challenge is not the failure of its ideals, but the incompleteness of the sovereign architecture required to uphold them.
