Keynote speech by President António Costa at the opening of the Bled Strategic Forum

We cannot anymore rely just on our allies when facing threats. We must take greater responsibility for our own destiny. That is why, I want to affirm one clear message on behalf of the European Union: We stand for a world where peace is protected, partnerships are genuine, and where the principles of the United Nations Charter are upheld—not just in words, but in action. Europe does not retreat. Europe engages.

First, Europe has stood firmly with Ukraine against Russia’s war of aggression, as the truly indispensable partner. Our support has helped Ukraine remain sovereign after more than three years of war. Together with our Member States, the EU has mobilized over €170 billion—the largest contribution from any global donor—supporting Ukraine’s defence, economy, energy grid, and institutions.

Our security is tied to Ukraine’s resilience. But equally, to the idea that power cannot trump law. We are also supporting Ukraine’s reconstruction and its path to EU membership. This is not a political slogan. It is a strategic reality that we are shaping every day.

Also there is a need to act together—engaging more actively with our partners in the region and speaking with one strong European voice.

Let me be clear. Unanimity in the Common Foreign and Security Policy is not a right to veto, but on the contrary the special responsibility for each Member State to build compromises in a spirit of loyal cooperation.

Geopolitical naiveté is over. That is why we are massively increasing our defence investments—to reinforce our own security, strengthen our industries, and create jobs across Europe. This also enhances our credibility and influence on the global stage. Peace without defence is an illusion. Soft power alone is not enough in a world where hard power too often prevails.

Finally, let me conclude by addressing our own future. The European Union is not a closed club. We are a community of values and a project of peace and prosperity—and that project is not yet complete. The accession paths of the Western Balkans, Moldova and Ukraine are not just promises. They are priorities. These countries are at the heart of Europe, and they are part of Europe’s future.

In the coming years, we must prepare the Union for enlargement—through reforms, budget adjustments, and strengthened governance. Enlargement will not be easy. But it will be worth it. It is the best investment we can make—to reconcile nations and histories, and to build a more united continent. We will continue to work with all accession partners and take advantage of this positive momentum on enlargement.

In today’s fragmented world, the European Union chooses to act—not through power alone, but through partnership, principle, and perseverance. We will stand with those who uphold international law—not with those who seek to dismantle it. And we will keep building a stronger Europe—not for ourselves alone, but for the benefit of global peace, justice, and cooperation.

This is Europe’s promise. This is Europe’s purpose.
