History has taught us – often at a painful price – that isolationism and unilateralism breed instability. Eighty years ago, in the aftermath of the utter devastation brought about by the Second World War, the United Nations was born to prevent us repeating the mistakes of the past. With the UN Charter, a new era of international cooperation and a rules-based order was forged, grounded in the values and principles of justice and international law. The European Union has always upheld and will continue to uphold the UN Charter and its fundamental principles: sovereignty, equality of Member States, territorial integrity, political independence, and self-determination. These are not abstract ideals; they are the foundation of international peace and security.

Yet, as we celebrate this milestone, we face grave challenges to our international order. Russia’s unprovoked, illegal war of aggression against Ukraine is a direct assault on peace, security, and the very principles upon which the United Nations was founded. This war underscores that the rule of law must never be replaced by the rule of force. In many other conflicts raging from the broader Middle East, Sudan, Yemen, the DRC and elsewhere, warring parties must remember that even wars have rules.

As the geopolitical context evolves, the European Union will continue to be a credible, reliable, and forward-looking partner to the United Nations. At a time when others turn inward, the European Union steps forward: to lead, to partner, and to build bridges. Our commitment to multilateralism is not just a matter of principle—it is a matter of global necessity.
