The transatlantic relationship was never merely an alliance between states. It was, rather, a geopolitical idea of order, held together not only by shared values. After 1945, a strategic architecture emerged: American power, European economic recovery, NATO security, open markets, and the shared realization that freedom does not survive without protection. Anyone speaking today about a distancing between the EU and the United States is therefore not only speaking about diplomatic irritation, but about a possible tectonic shift in the world order as we know it. European states and the United States were never always of one mind. Vietnam, Iraq, trade conflicts, data protection, China, and the Middle East show that transatlantic unity was never self-evident. What mattered, however, was that despite all differences, there was a common strategic center. It is precisely this internal logic that now seems increasingly fragile. If the EU and the United States were to seriously move away from one another, this would have several effects.
The first would be economic. The transatlantic economic area is one of the densest in the world. Trade in goods and services between the EU and the United States more than doubled between 2014 and 2024, reaching around €1.68 trillion in 2024. Added to this is a massive web of mutual investment: in 2023, EU and U.S. companies together held investments worth around €4.7 trillion in each other’s markets. This affects supply chains, jobs, research, energy, capital, insurance, technology, industrial standards, and much more. A distancing would therefore not simply mean that Brussels and Washington speak to each other less politely. It would inject enormous uncertainty into an economic space that depends on predictability. Investors and capital seek clarity and calm waters. If the transatlantic axis becomes fragile, companies will reassess their supply chains, locations, and investments. That means higher costs, slower decisions, less trust, and therefore the immediate weakening of both sides.
The second effect would be security-related. For decades, Europe became accustomed to the United States providing the ultimate security guarantee. That was convenient and cheaper. But strategically, it was shortsighted. The war in Ukraine destroyed this illusion. It showed that war in Europe is not history. At the same time, Washington, regardless of administration, has demanded that Europe assume greater responsibility for its own defense. In 2025, NATO decided in The Hague that Allies should invest 5 percent of GDP annually in defense and security-related spending by 2035, including at least 3.5 percent for core defense requirements. Who will actually meet this target remains to be seen. Some countries, such as left-led Spain, already appear to be moving toward confrontation. Regardless of that, it will become clear that the burden within the alliance will shift. The military capacities of European NATO states will grow. But there is a difference between European independence and transatlantic decoupling. Independence means Europe is growing up. Decoupling means Europe stands alone before it can truly walk. That is precisely where the danger lies. An EU that distances itself from the United States without being sufficiently capable militarily, technologically, and politically would not become more sovereign. It would become more vulnerable. Strategic autonomy sounds good as long as it is not merely another word for helplessness. Ultimately, power does not emerge from rhetoric for election campaigns and the domestic press. Power emerges from capabilities.
The third effect would concern China. Beijing would not even have to actively create a deep transatlantic split. It would only have to use it. The difference from the West lies particularly in the time horizon: the People’s Republic understands power in long terms — through infrastructure, raw materials, technology, ports, markets, standards, and dependencies. This thinking is not fed solely by communist party discipline, but also by older civilizational ideas of order. Confucianism does not explain the entirety of Chinese power politics, but it points to traditions of thought in which order, hierarchy, continuity, and strategic patience are central categories. Europe would then be tempted to balance between Washington and Beijing. But balance is only a strategy if one has enough weight of one’s own. Those who are not strong enough do not balance; they are balanced. That is precisely the danger for the EU. This is by no means an argument for European dependence on the United States. The old continent must emancipate itself and go its own way. But not in opposition to the Western idea.
There is also a psychological factor, especially in Asia, that should not be underestimated. For decades, the West was regarded as a model: economically successful, institutionally stable, technologically leading, and culturally attractive. Those who wanted to modernize oriented themselves at least partly toward Western standards. But this self-evidence is crumbling. In many parts of Asia, the feeling is growing that progress no longer necessarily means Westernization. One can rise economically, modernize technologically, and gain geopolitical weight without adapting politically or culturally to the West. A visible distancing between the EU and the United States would significantly reinforce this perception. It would be a confirmation: the West remains important, but it is no longer without alternative. That is precisely what changes the rules of the game. The real competition therefore does not take place only in markets, sea lanes, or technological standards. It also takes place in the mind. If the West loses its internal cohesion, it does not immediately lose its power. But it loses part of its magnetic appeal. And in the long run, that could weigh more heavily than many diplomatic conflicts.
The fourth effect would concern Russia. For Moscow, a lasting estrangement between Europe and the United States would be a strategic advantage. Power does not work only through weapons, but through credibility. If President Putin gains the impression that Washington and Brussels no longer respond in a united way, risk becomes more calculable. And calculable risk is more likely to be taken. This does not automatically mean war. It means more room for pressure, disinformation, cyber operations, energy leverage, and influence networks.
The fifth effect would be psychological. The West lives not only from institutions, markets, and military strength, but also from confidence in its own ability to act. A distancing between the EU and the United States would be read globally as a signal: the West is no longer united. For many states of the so-called Global South, that would not automatically be negative. On the contrary: they would recognize and use new room for maneuver. India, Brazil, the Gulf states, Turkey, Indonesia, and Saudi Arabia are already recalibrating their positions. Not out of hostility toward the West, but out of the logic of interests.
The world is not waiting for Brussels to resolve its internal identity crisis or for Washington to happen to have a good day. Power-political spaces are occupied as soon as they emerge. That is where the real shift lies. The strategic logic is simple: whoever outsources responsibility pays interest later. For decades, Europe outsourced security, underestimated energy dependencies, neglected industrial substance, and too often confused political morality with strategic capability. Power costs money. Weakness costs even more. The United States, in turn, has sometimes treated Europe as a weak partner, but also as a market, an ally, and a geopolitical extension of its order. Both sides have benefited from one another. But both sides have also made themselves comfortable.
A distancing could therefore also have a productive effect if it leads not to separation, but to maturation. Europe would finally have to learn to see power not as a moral problem, but as a prerequisite for political shaping. And the United States would have to accept that an adult European partner is not automatically a former partner. But that requires clarity. European politicians should not frame strategic autonomy as an anti-American reflex. And U.S. politicians must not interpret European independence as disloyalty. The future lies in a new division of labor.
The West therefore faces a sober choice. Either it modernizes its partnership – with more European responsibility, more American realism, and fewer mutual illusions – or it will watch other powers definitively fill the vacuum. Because in geopolitics, emptiness never remains empty.
