NATO Secretary General Mark Rutte has issued a clear warning to European leaders, stating that Europe is currently incapable of defending itself without military backing from the United States. Speaking to members of the European Parliament in Brussels, Rutte dismissed the idea of European strategic autonomy without US involvement, calling such expectations unrealistic under present conditions.
Rutte said that for Europe to become fully independent in defence matters, military spending would need to increase significantly beyond current targets. According to him, even meeting existing defence commitments would not be sufficient to replace the scale, capability and deterrence provided by the United States. He stressed that transatlantic cooperation remains essential for European security.
During his address, Rutte underlined the long standing interdependence between Europe and the United States within NATO. He noted that shared military infrastructure, intelligence cooperation and joint deterrence strategies cannot be easily replicated without Washington’s participation. He added that both sides continue to rely on each other to maintain stability across the Euro Atlantic region.
The comments come at a sensitive moment for the alliance, following recent tensions sparked by remarks from US President Donald Trump concerning Greenland. Greenland is a semi autonomous territory under Denmark, a NATO member state. Trump had earlier suggested the possibility of annexing the island, citing its strategic and mineral importance, and warned of trade measures against European partners backing Denmark.
Although the rhetoric raised concerns across Europe, the situation eased after discussions led to what was described as a framework agreement. Rutte was reportedly involved in facilitating dialogue between the parties, though details of the understanding have not been made public.
The episode has once again highlighted Europe’s dependence on US security guarantees, particularly at a time when global geopolitical tensions are rising. While European nations have increased defence spending in recent years, NATO officials argue that the pace and scale remain insufficient to independently counter major security threats.
Rutte also cautioned against underestimating the complexity of defence preparedness. He said military capability is not only about budgets but also about logistics, coordination, advanced technology and political unity, areas where NATO’s integrated structure plays a crucial role.
European leaders continue to debate the concept of strategic autonomy, especially amid uncertainty over future US foreign policy. However, Rutte’s remarks suggest that NATO leadership sees no viable alternative to the transatlantic alliance in the foreseeable future.
As discussions on defence spending and burden sharing continue within Europe, the NATO chief’s message was clear: without sustained cooperation with the United States, Europe’s ability to ensure its own security remains limited.
