European NATO is emerging as a contingency idea in informal talks among several European allies, according to reports published on 15 April, as governments prepare for the possibility that the USA could reduce its role in the Atlantic alliance or withdraw from it altogether. The discussions are not about replacing NATO overnight, but about keeping its military and political structures functioning with a stronger European backbone if Washington steps back.
The reporting, first detailed by The Wall Street Journal and picked up by Swedish broadcaster TV4, suggests that the talks involve a group of like-minded allies including France, Germany, the United Kingdom, Poland and Sweden. The broader issue, however, goes well beyond Stockholm. What is taking shape is a debate about whether Europe can build enough command capacity, defence production and political coordination to preserve deterrence against Russia even with a much smaller American role.
Why the idea of a European NATO is gaining ground now
The immediate trigger is the renewed uncertainty around USA commitments to European security. In recent weeks, USA President Donald Trump has again raised the possibility of scaling back or even leaving NATO, while also questioning the value of the alliance for Washington. That has pushed several European governments to move from a long-running theoretical debate about “strategic autonomy” to more concrete contingency planning.
The reported talks remain informal, which is significant in itself. European governments are trying to avoid signalling panic or a formal rupture inside NATO. At the same time, they appear to be acknowledging that relying indefinitely on American leadership is no longer a safe assumption. In this sense, the idea of a European NATO is less a new alliance than a fallback structure inside the existing one.
What Europe would need to replace inside NATO
If the USA stepped back, the biggest challenge would not be the NATO label itself but the capabilities behind it. The alliance’s military command has long depended on American leadership. NATO’s Supreme Allied Commander Europe, or SACEUR, is traditionally a USA officer who oversees the alliance’s military operations. A more European-led NATO would therefore require changes not just in staffing but in operational planning, logistics and intelligence-sharing.
Europe would also need to reduce its dependence on USA military equipment and support systems. That includes air and missile defence, long-range strike capabilities, strategic lift, satellite-based intelligence and command-and-control infrastructure. These are areas where many European armed forces have improved since Russia’s full-scale invasion of Ukraine, but where the USA still provides critical enablers.
The most difficult issue remains nuclear deterrence. France and the United Kingdom are Europe’s two nuclear powers, but neither currently replicates the scale of the American nuclear umbrella inside NATO. Any serious attempt to build a more autonomous European pillar would therefore raise politically sensitive questions about whether Paris and London should play a larger deterrence role on behalf of the continent.
Germany’s shift has changed the balance of the debate
One reason the discussion appears more serious now is Germany’s changing position. For years, Paris argued that Europe should be able to act more independently on defence, while Berlin was more cautious and preferred to keep the USA clearly at the centre of the alliance. According to current reporting, that resistance has softened.
That matters because a more European NATO cannot work without German political, industrial and financial weight. France can provide strategic vision and nuclear capabilities, the United Kingdom can provide major military assets and intelligence links, and eastern allies such as Poland bring urgency because of their geographical exposure to Russia. But Germany remains central if Europe wants to scale procurement, replenish stockpiles and support a larger command role for Europeans.
Europe is already trying to build a stronger defence base
The current debate is also linked to broader European efforts to strengthen defence production. The EU has already launched SAFE, a loan instrument worth up to €150 billion, to support joint procurement and reinforce Europe’s defence industrial base. That does not create a European army, and it is not a substitute for NATO. But it does show that European governments and the EU executive are trying to close some of the capability gaps that a more self-reliant NATO structure would expose.
This is also where the debate intersects with Nordic and Baltic security. For countries on NATO’s northern and eastern flanks, the question is not abstract. A weaker USA role would have direct consequences for deterrence in the Baltic Sea region, the High North and the Arctic. That is why the debate increasingly involves not just France and Germany, but also countries such as Poland, Finland and Sweden.
A fallback plan, not a formal break with Washington
For now, there is no sign that European allies are preparing to dissolve NATO or openly replace the transatlantic link. Publicly, most governments continue to say that keeping the USA inside the alliance is in everyone’s interest. The emerging discussion is instead about what happens if that political assumption fails.
That distinction is important. The phrase “European NATO” can sound more dramatic than the reality described so far. What appears to be under discussion is a contingency plan: more Europeans in top military roles, greater independence from USA weapons systems, and a stronger industrial and political base able to keep NATO functioning even under severe transatlantic strain.
The fact that these conversations are taking place at all is nonetheless politically significant. It suggests that European allies no longer see American security guarantees as automatically permanent. For Europe, the strategic question is no longer whether it should do more within NATO. It is whether it can do enough, and fast enough, if the alliance’s American pillar becomes less reliable.
