NATO crisis forces have already been affected by a reduction in the USA contribution, Secretary General Mark Rutte said in Brussels on Thursday, as defence ministers met to discuss how European allies and Canada can fill the gaps left by Washington’s decision.
USA cuts have already changed NATO crisis planning
Rutte confirmed that the reduction announced by the USA is not a future scenario but an immediate change to NATO’s crisis-force planning. “The question came up yesterday: is this immediate or not? It is immediate,” he told reporters during the ministerial meeting.
The decision concerns national capabilities assigned to NATO in a crisis, rather than the automatic withdrawal of all USA forces from Europe. Rutte sought to distinguish between planning assumptions and wartime reality, saying that if war broke out, “all allies, including the USA,” would use everything available to ensure NATO could fight.
The clarification matters because NATO crisis forces are a central part of the Alliance’s deterrence model. They include military assets that member states make available for a rapid response in an emergency, even if they remain under national control in peacetime.
European allies move to cover the gaps left by Washington
According to Rutte, other NATO countries are now expected to increase their contributions to compensate for the reduced USA role. The shift comes as Washington asks European allies to take more responsibility for the conventional defence of Europe.
Reuters reported that some of the gaps concern high-end military assets, including fighter aircraft and drones. Belgium has already indicated that it will contribute more, including F-16 fighter jets and MQ-9B SkyGuardian drones. German Defence Minister Boris Pistorius warned, however, that replacing certain capabilities could take time, especially in areas such as long-range strike weapons.
The USA decision was communicated to allies last month and is part of a broader review of American military deployments in Europe. USA Defence Secretary Pete Hegseth said in Brussels that the review would last up to six months and would aim to ensure that Europe takes the lead in its own defence while the USA preserves the capacity to respond to global threats.
Rutte frames the shift as a stronger Europe inside NATO
NATO has presented the change as part of a broader move towards a stronger European pillar inside the Alliance. On Wednesday, ahead of the ministerial meeting, Rutte said allies needed “more forces, more resources and a much stronger industrial base,” linking the issue to higher defence investment and a more balanced sharing of responsibility.
The message is politically sensitive. For European governments, the reduction reinforces a long-standing debate about dependence on USA military capabilities. For Washington, it reflects a strategic demand that European allies and Canada contribute more, especially as the USA faces security pressures beyond the European theatre.
The issue will also shape preparations for the next NATO summit, where allies are expected to discuss defence spending, capability targets and the practical balance between USA leadership and European responsibility.
Nordic and Baltic security depends on credible reinforcements
For the Nordic countries, the debate is particularly relevant. Denmark, Norway, Finland and Sweden are now all part of NATO, while the Baltic Sea region has become one of the Alliance’s most strategically exposed areas after Russia’s full-scale invasion of Ukraine and Finland and Sweden’s accession to NATO.
Finland and Sweden joined the Alliance with the expectation of stronger collective defence planning in Northern Europe. Norway and Denmark already play important roles in the North Atlantic, the Arctic and Baltic Sea security architecture. Any reduction in USA-assigned crisis capabilities therefore raises practical questions about how quickly European allies can replace essential assets.
Rutte’s message was designed to avoid panic: the USA remains inside NATO’s defence architecture, and Washington would still be expected to act in a major conflict. But the immediate reduction confirms that European NATO members are entering a more demanding phase, in which higher defence spending must translate into usable forces, industrial capacity and credible reinforcement plans.
