NATO Secretary General Mark Rutte argued against creating a single European army, saying the idea would require countries to give up their national armed forces. Speaking to students at Tallinn University of Technology in Estonia, he said sovereignty concerns make such a step unlikely and that NATO's command and control structure removes any need for it.

Rutte warned that building parallel structures inside the European Union alongside NATO would delay decisions and leave allies exposed. He noted that NATO's system enables 32 national armies to operate together. Asked about European Commission President Ursula von der Leyen's proposed European Security Council, he said such a body would work alongside NATO, since the EU carries its own responsibility for resilience and hybrid issues.

Rutte said drone and counter-drone technologies need further development and called for layered, cost-effective air defenses to protect cities and critical infrastructure. He also pointed to a NATO center in Poland studying lessons from the Russia-Ukraine war. Asked when hybrid attacks qualify as armed aggression under Article 4 or 5, he said the alliance deliberately keeps the threshold ambiguous so adversaries gain no extra information.

Key Takeaways

• Rutte says a European army would require states to abandon national armed forces and is unlikely on sovereignty grounds.
• NATO's command structure already lets 32 national armies operate together, he says.
• Rutte calls for better drone and layered air defense capabilities and says NATO deliberately keeps its hybrid attack threshold unclear.
