On 1 October 2025, the capitals of Europe turned their gaze to Copenhagen, where an informal European Council summit gathered the heads of state or government of the EU’s 27 member states. The meeting—hosted by Danish Prime Minister Mette Frederiksen and chaired by European Council President António Costa—arrived at a moment of heightened tension and urgent strategic decisions. This gathering was not scheduled as a “regular” summit but rather as an informal check-in, intended to steer the EU’s approach on defence, security, and support for Ukraine between formal Council sessions. It preceded, and was to feed into, a full European Council meeting later in October. Below is a deeper look at the context, key topics, tensions, and possible outcomes of the Copenhagen meeting.
Setting the Stage: Why Copenhagen Now?
Rising Security Pressures & Drone Incursions
In recent weeks across Europe, a wave of unidentified drone activity and airspace violations—notably over Denmark, Poland, and the Baltic states—has rattled member states and raised alarms in capitals. In Denmark, drone sightings forced closures of airports and disruptions to military installations. Concern is widespread that these incidents might be part of a broader “hybrid warfare” campaign — probing responses, testing readiness, and challenging European defence coordination. For hosts in Copenhagen, the issue was immediate: the summit itself would need to be protected from aerial threats. Denmark activated heightened security measures—deploying precision radar installations at Copenhagen Airport and receiving assistance (anti-drone systems, radar units, personnel) from France, Germany, Sweden, the UK and others.
Ukraine and the War’s Endgame
The war in Ukraine remains the central security challenge of the continent. The summit serves as a platform to re-energize European support: military aid, financial assistance, sanctions regimes, and the longer-term objective of Ukraine’s EU accession. Leaders have emphasized that ongoing support must be “reliable and predictable.”
A particularly contentious proposal is to use frozen Russian central bank assets held in Europe (estimated in the hundreds of billions of euros) to provide Ukraine with a “reparations loan” or financial bridge while waiting for a future peace deal. Some see this as a pragmatic way to bypass delays in aid, but legal, financial, and political constraints remain strong.
European Defence Ambitions & The 2030 Goal
The EU has set an ambition to boost its defence readiness by 2030—a vision of more autonomous, resilient, and cooperative European defence capacities. The informal summit is expected to narrow down what concrete steps can be taken now: joint procurement, coordinated capability development, defense industrial policy, and governance mechanisms. Crucially, discussions also include protecting the EU’s eastern flank and aligning efforts with NATO. One of the more ambitious ideas under discussion is a European “drone wall” — a system of sensors, radars, and countermeasures deployed along the EU border to detect and neutralize drone incursions.
Flashpoints & Challenges
Legal, Financial & Political Constraints
Using frozen assets: Belgium and other states have raised objections about violating sovereign immunity, central banking norms, and potential eurozone risks.
Unanimity vs. flexibility: Some EU decisions still require unanimity, giving fringe holdouts leverage. Proposals may need to be structured to avoid veto points.
Diverging threat perception: Not all member states view Russia as equally imminent a danger; southern members, for example, might prioritize migration or energy over defence.
Cost and burden-sharing: Joint procurement is easier said than done—aligning national budgets, procurement cycles, and industrial interests is fraught with friction.
U.S. Uncertainty & Transatlantic Dynamics
With the United States’ global focus shifting, notably under President Trump’s “America First” approach, European leaders are under pressure to step up their own defence capabilities. The Copenhagen summit signals Europe’s attempt to hedge against reliance on Washington.
Symbolic vs. Substantive Outcomes
Informal summits often issue declarations and guidelines rather than binding commitments. The real test will lie in translating rhetoric into deliverables by the October formal European Council.
What to Watch Moving Forward
1. Deliverables in October: Whether the formal European Council on 23–24 October turns Copenhagen’s ideas into binding decisions will be decisive.
2. Drone wall feasibility: Will pilot projects or funding commitments emerge?
3. Treatment of Russian assets: Will any consensus be reached on how to legally and ethically mobilize them?
4. Ukraine’s membership path: Despite the war, Brussels will want to keep the membership door open—how far can that go under current divisions?
In sum, the Copenhagen meeting may not yet rewrite European security architecture, but it has the potential to set the tone and direction for the months ahead. With growing unease over drone incursions, pressure to support Ukraine, and doubts about transatlantic backing, the summit could mark the moment when Europe embraces a more assertive strategic posture—or reveals how fragile its unity really is.
