EAST AND WEST

As American commitment becomes less predictable, Paris is positioning itself as Europe’s strategic pivot—without the means to fully assume Washington’s role.

The idea has moved from diplomatic salons in Paris to the mainstream of European strategic debate with unusual speed: Europe may have to prepare for a future in which the United States is still formally present in NATO, but no longer functions as its unquestioned military backbone. In that context, France is increasingly presented not as an alternative to Washington, but as the only plausible European state capable of holding together a more autonomous security architecture.

This is not a sudden rench ambition. It is the continuation of a long intellectual tradition in French strategic thinking, one that has always been uneasy with full dependence on American guarantees. What has changed is not Paris, but the strategic environment: the war in Ukraine, the return of large-scale conventional conflict to Europe, and the political volatility of US commitments under different admin- istrations have all combined to turn old French instincts into what now looks like a European planning problem.

Even without a formal US withdrawal, even without a dramatic rupture in NATO, incremental changes in American posture would already force a redesign of European defence. A smaller permanent US presence, reduced willingness to lead early crisis escalation, or a more transactional approach to alliance obligations would leave Europeans with a gap that cannot be filled overnight. It is in this gap that the French argument acquires weight.

France presents itself as the only EU member with the strategic vocabulary and institutional memory to operate at continental scale. It is the Union’s sole nuclear power, one of the few European states that still maintains a globally deployable military, and a country whose defence planning still rests on the assumption that war is not an abstract contingency but a political reality that must be prepared for in advance. In Paris, the language of “strategic autonomy” is not new branding but inherited doctrine, shaped by historical episodes such as the Suez crisis, when French and British forces were forced to retreat under American pressure. That moment left a deep imprint: alliances are necessary, but dependence is dangerous.

Yet the gap between political ambition and material capability remains stark. France can define frameworks, propose doctrines, and initiate coalitions, but it cannot replicate the structural depth of American power in Europe. The United States does not only provide troops. It provides an entire system of warfighting: intelligence fusion, satellite reconnaissance, strategic airlift, missile defence integration, and logistical sustainment over time and distance. Europe, even collectively, remains unevenly equipped in these areas. France is no exception, despite its relative strength.

This structural imbalance becomes most visible when discussing Ukraine. The war has become a practical stress test for European claims of autonomy. European governments have already provided substantial financial support to Ukraine, in some categories exceeding American contributions. But the decisive difference lies elsewhere: in the types of weapons systems, the speed of delivery, and the depth of industrial capacity behind them. Where Europe struggles most is not in political will or aggregate spending, but in replacing high-end US enablers such as long-range precision strike systems and advanced integrated air defence at scale.

In that sense, the debate about France leading a more autonomous European NATO is not primarily about money or troop numbers. It is about whether Europe can generate a coherent military system at all. The French argument implicitly acknowledges this: Paris does not claim to replace the United States, only to organise Europe in such a way that the absence of American primacy does not immediately translate into strategic paralysis.

The nuclear dimension reinforces both France’s centrality and its limits. President Emmanuel Macron has recently pushed for a broader European reflection on the role of French deterrence in continental security. The logic is clear: in a world where American guarantees appear less automatic, Europe’s only independent nuclear capability becomes more politically relevant. Yet France has not offered anything resembling a shared nuclear command structure. The arsenal remains entirely national, the decision to use it remains exclusively in Paris, and there is no indication of any shift towards a NATO-style nuclear sharing model. What is evolving is not control, but signalling: a willingness to extend the psychological reach of French deterrence to European partners without diluting sovereignty over it.

At the same time, Europe’s broader defence-industrial limitations remain unresolved. The collapse of flagship projects such as the Franco-German Future Combat Air System illustrates how difficult it is to translate political rhetoric about European sovereignty into functioning joint programmes. Diverging operational requirements, industrial competition, and uneven strategic priorities continue to fragment even the most ambitious initiatives. Germany’s growing reliance on American platforms, particularly in air power, further complicates the picture.
All of this means that the idea of a “French-led NATO in Europe” is less a blueprint than a tension. It captures a real shift in expectations about US reliability, but it does not resolve the underlying structural dependencies. Europe may want to think in terms of autonomy, but it continues to operate within an architecture that is still fundamentally transatlantic.
There is also a political uncertainty that no strategic document can eliminate. France itself is not stable in its current strategic direction. The consensus around Macron’s vision of Europeanised deterrence and greater strategic autonomy is contested domestically. The rise of political forces sceptical of military engagement abroad and critical of NATO integration introduces a degree of volatility into what is often presented as a long-term French state project. In that sense, Europe is not only asking whether France can lead a more autonomous NATO-like structure, but whether France will maintain the same strategic orientation after its next electoral cycle.

For now, France remains indispensable without being sufficient. It is the only European power capable of initiating a serious discussion about post-American security structures, but it cannot by itself provide the material foundation for them. A European security system with less America will not be a French version of NATO. It would be, at best, a more fragmented, more fragile, and more improvisational arrangement, held together by partial capabilities, shifting coalitions, and the continuing, if diminished, presence of the United States.

The real question, therefore, is not whether Paris can replace Washington. The question is whether France can organise Europe enough to prevent the gap between American retrenchment and European readiness from becoming a structural vulnerability. At present, the answer is uncertain.
