António Costa Warns of Escalating Russian Hybrid Threats in Europe

The call for mobilization comes as transatlantic tensions rise over potential diplomatic overtures. While the U.S. administration has extended an invitation to Russia for the upcoming G20 summit in Miami, European leaders remain deeply skeptical. Polish Prime Minister Donald Tusk voiced concern that such an invitation might be misinterpreted by the Kremlin as a green light to intensify its aggressive posture rather than a genuine path toward a just peace.

Simultaneously, the security landscape appears increasingly fragile. A new assessment from Danish intelligence predicts that Russian hybrid activity will grow more frequent in the coming months, carrying a persistent risk of escalation. Seán Clancy, chair of the EU Military Committee, underscored the gravity of the situation for the private sector, noting that regional prosperity has become inextricably linked to the ability of member states to secure their borders against these evolving, non-conventional threats.
