The Price of Internal Reform

Even before U.S. proposals entered the fray, EU insiders were clear: absorbing post-war countries‘ demands for reforms to EU governance. Candidate states with fragile democratic institutions will stretch the Union’s unanimity-based decisions on foreign policy, sanctions, and defence. Unanimity – particularly in areas like sanctions re-imposition – already allows individual capitals (e.g., Hungary) to behave as de facto veto players, slowing support for Ukraine and complicating sanctions enforcement.

Technical fixes –  such as expanding Qualified Majority Voting for certain external policy decisions or creating transitional safeguards – are widely discussed in policy circles. But without consensus among existing members, these remain elusive. For Ukrainian and other aspirants, this messy internal dynamic poses a harsh reality: Brussels must reform not just its institutions, but its political culture of unanimity, if it is to govern a 30+ member Union credibly.

Two Strategic Alternatives: “Protectorate Europe” vs. “Gradual Integration”

In policy forums, two competing visions have crystallised:

1. Protectorate Europe:

Under this logic, Washington steers peace, chairs the enforcement council, and controls reconstruction finance, potentially via frozen Russian assets — relegating the EU to funding and secondary roles. This framework could anchor Ukraine’s recovery in U.S. strategic priorities rather than EU regulatory integration, diluting the transformative power of EU law and the acquis as engines of democratic consolidation. European leverage would be replaced by U.S. agenda-setting.

2. Gradual Integration:

The EU could pursue asymmetric accession, offering deep integration of markets, regulatory frameworks, and sectoral cooperation long before formal membership. This “four freedoms lite” model would bind Kyiv, Chişinău, and others into Europe’s economic and legal orbit while deferring full accession until institutional reforms are complete. Gradual integration maximises the EU’s normative pull and reduces immediate political and budgetary strain — but it cannot substitute for sovereign security guarantees or fully deter future aggression without military backing.

For EU policy-makers, the choice isn’t simply technical. It goes to who defines conditionality, who dictates post-war reconstruction priorities, and how sovereignty and security are guaranteed within an enlarged Europe.

The Security Guarantee Dilemma

The U.S. plan’s proposed security guarantees link peace to a non-aggression pact and limitations on Ukraine’s NATO prospects – effectively transforming Kyiv into a neutralised buffer. Europe, meanwhile, debates independent security guarantees outside NATO, tied to expanded defence cooperation, arms production capacity, and reduced dependency on U.S. supplies. Yet internal veto players complicate unified EU defence policy, with capitals like Budapest slowing assistance and shaping bloc cohesion debates.

This convergence of enlargement, peace negotiations, and security commitments functions as a triple stress test for Europe:

• Can the EU reform its decision-making fast enough to respond coherently to a fast-moving peace process?
• Can Europe finance and coordinate defence and reconstruction at scale without defaulting to U.S. preferences?
• Can it manage internal spoilers while negotiating accession with countries whose future security postures may be partially externally determined?

Those are not mere bureaucratic questions; they are strategic vulnerabilities that adversaries can exploit.

Signalling to Moscow, Kyiv, and the Global South

By 2030, international observers – in Kyiv, Moscow, and across the Global South – will evaluate Europe on two linked benchmarks: Did the EU defend its principles of territorial integrity? And did it match rhetoric with credible institutional and financial commitments?

If Brussels accommodates a U.S. framework that legitimises territorial gains by force, it risks hollowing out its sanctions policy and undermining the rules-based order it claims to champion – weakening its normative appeal from Georgia to Syria. Conversely, an overly rigid stance without credible backing risks alienating partners who prioritise war termination and reconstruction – a critical concern for Global South states that balance legal norms against humanitarian urgency.

Europe’s diplomatic task is to help shape, not merely react to, peace frameworks – by securing robust compliance mechanisms, reversible sanctions relief, and an active EU role in reconstructing governance and territorial disputes.

Conclusion

Europe’s “2030s Big Bang” enlargement is no longer an internal governance project; it is a litmus test of the EU’s ability to act as an autonomous strategic actor in a system where American diplomacy may shape outcomes faster than European deliberation allows. The interplay between Trump’s 28-point Ukraine plan and EU enlargement will not only chart the continent’s borders but determine whether Europe remains an architect of its own security, or watches others draw its map for decades to come.
