Europe’s defence debate moved from nuclear deterrence to drones, air defence and military production at the first Euronews Defence and Space Summit on 30 September 2026. NATO Secretary General Mark Rutte, Bulgarian Prime Minister Rumen Radev, ministers, diplomats and defence-industry leaders offered sharply different assessments of the risks facing European countries.
The gathering was a policy discussion, not a new NATO or European Union decision. Its central question was whether Europe has the capabilities, industrial capacity and political unity needed to deter threats while supporting Ukraine.
Five themes dominated Europe’s defence summit
Russia’s full-scale invasion of Ukraine has forced governments to reconsider defence spending, weapons production and the resilience of critical infrastructure. Speakers also pointed to hybrid activity, including alleged interference and attacks affecting European countries.
The main issues raised during the summit were:
- the risk of nuclear escalation and the need for diplomatic engagement;
- NATO’s response to threats against allied territory;
- Europe’s shortage of air-defence systems and interceptors;
- the speed of technological change, particularly in drone warfare;
- the debate over whether European defence procurement should prioritise suppliers based in Europe or across NATO.
Radev calls for diplomacy over escalation
Bulgarian Prime Minister Rumen Radev challenged the current approach to supporting Ukraine, describing it as an unsuccessful attempt at “peace by force”. He argued that governments needed clearer political objectives, a realistic assessment of Russia’s strategy and stronger diplomatic engagement with the Kremlin.
Radev also warned that nuclear weapons had to remain part of Europe’s security calculations. His comments followed reporting about a Russian document containing threats to use all available capabilities, including nuclear weapons, to defend Russian territory. The document and its implications were not independently established in the summit discussion.
His intervention highlighted a continuing divide in European security policy: whether deterrence should rely primarily on military pressure and increased support for Ukraine, or whether diplomacy should play a larger role in reducing the risk of escalation.
Rutte says NATO territory is not facing an immediate threat
NATO Secretary General Mark Rutte adopted a more reassuring tone. He rejected what he described as Russian nuclear threats and emphasised that NATO is a defensive alliance.
Rutte said there was no immediate threat to NATO territory and insisted that the alliance was prepared to defend every part of its territory if necessary. He also argued that Russia could not defeat NATO, while calling for a calm and coordinated response.
At the same time, Rutte identified air defence as one of Ukraine’s most urgent military needs. Russia’s sustained aerial attacks have placed pressure on Ukraine’s supply of interceptors, and he urged allies to provide additional Patriot systems and ammunition.
Hybrid attacks and air defence concerns
Belgian Defence Minister Theo Francken warned that European countries could face a difficult winter as hostile interference increases. He placed air attacks and air-defence capacity at the centre of the challenge, calling for larger stocks, faster production and a stronger industrial base.
Francken referred to incidents including an arson attack at a defence robotics company in Estonia and an attempted drone attack at Leipzig airport in Germany. The summit discussion presented such incidents as examples of the wider hybrid-security environment, although responsibility and legal findings can differ from case to case.
Francken also said European countries should learn from Ukraine’s battlefield experience, particularly the speed at which drone technology changes. Maintaining large stocks of equipment may not be enough if systems become obsolete within months.
He acknowledged Belgium’s previous low level of defence spending, saying the country had increased expenditure but could not rebuild capabilities neglected over decades within a short period.
US officials debate the future of European defence procurement
The summit also exposed tensions over the relationship between European defence industrial policy and the United States. Matthew Whitaker, the US ambassador to NATO, said Washington remained committed to European security while asking allies to contribute more.
Andrew Puzder, the US ambassador to the European Union, criticised proposals to give preference to “Made in Europe” products in public procurement, including defence equipment. He argued that capability and availability should determine purchasing decisions rather than the geographical origin of a supplier.
Puzder promoted a “Made in NATO” approach that would give US defence companies wider access to European procurement. The disagreement reflects a broader policy question: should higher defence spending strengthen Europe’s domestic industrial base, or should procurement remain open to the widest possible group of NATO suppliers?
What does the summit mean for the EU?
The event did not produce a binding EU measure, new sanctions package or formal NATO decision. Instead, it illustrated the pressures influencing European security policy as governments seek to expand military capacity, support Ukraine and protect infrastructure from hybrid threats.
For the European Union, the debate is relevant to discussions about defence-industrial cooperation, public procurement and strategic autonomy. However, NATO remains the central military alliance for collective defence, while national governments retain major responsibility for defence spending and armed forces.
Ireland is not a NATO member, so the alliance’s collective-defence commitments do not apply to it in the same way as they do to NATO allies. Nevertheless, developments affecting European security, critical infrastructure, defence supply chains and EU policy can have wider implications for Ireland and other EU member states.
What happens next?
The summit’s statements do not replace decisions by national governments, NATO bodies or EU institutions. The next steps will depend on political choices over:
- defence budgets and long-term procurement;
- air-defence production and the supply of interceptors to Ukraine;
- support for European and transatlantic defence industries;
- responses to hybrid attacks and threats to critical infrastructure;
- the balance between deterrence, diplomacy and escalation management.
For now, the discussions show that Europe’s defence challenge is broader than conventional military power. Nuclear risk, cyber and hybrid activity, drone warfare, industrial capacity and transatlantic relations are increasingly connected parts of the same security debate.
Conclusion
The Euronews Defence and Space Summit underscored the urgency of Europe’s defence debate without announcing a new institutional decision. Radev stressed the danger of nuclear escalation, Rutte sought to reassure NATO allies, Francken called for faster air-defence production, and US representatives challenged the direction of European procurement policy. The key takeaway is that European security policy will increasingly depend on both military readiness and the ability to produce, adapt and coordinate capabilities quickly.
