In Washington this week, as Ukrainian President Volodymyr Zelenskyy met with Donald Trump and European leaders, headlines celebrated solidarity and strategic resolve. Yet the real story—and the subtext beneath the headlines—is far more telling: Europe is being compelled to finance a massive arms buildup by purchasing some $90 to $100 billion worth of American weapons, all in an effort to secure U.S. security guarantees.
This moment encapsulates the core dynamic of the transatlantic alliance: Europe may wear the mask of autonomy, but its geopolitical moves are still happening on America’s terms. The continent is not acting from strategic independence—it is trading for it. And in doing so, it reveals just how long—and how tethered—its “leash of liberty” truly remains.
A well-appointed protectorate
Observing transatlantic diplomacy, one might see a partnership of equals. The choreography is flawless. But to mistake it for the play itself is to miss the point. For eighty years, Western Europe has operated not as an independent power, but as a remarkably well-appointed American protectorate. This is the foundational reality of the post-war order.
The arrangement began after 1945. A continent lay in ruins. The United States, the undisputed global hegemon, underwrote its reconstruction. The Marshall Plan was not charity; it was a strategic investment. It built a bulwark against Soviet expansion. The security architecture was formalized through NATO. Here, the U.S. shoulders the lion’s share of the burden.
In 2023, American defence spending accounted for 68% of the NATO total. The imbalance is stark. This trade-off was pragmatic. America provided the shield. Europe achieved unprecedented prosperity. But it did so by outsourcing its hard power. An entity that outsources its security cannot possess full geopolitical autonomy.
The rules of the game
This dynamic has been tested. Each test has only clarified the rules. When European interests diverge from American priorities, Washington asserts its prerogative. The 2003 Iraq invasion was a prime example. France and Germany refused to endorse the war. The diplomatic acrimony was intense. U.S. Secretary of Defense Donald Rumsfeld famously dismissed them as “Old Europe.” The message was clear: dissent was possible, but it could not alter the American course.
Energy policy offers another compelling case. The Nord Stream 2 pipeline was a cornerstone of Berlin’s economic strategy. Washington vehemently opposed it. The pipeline’s demise after the 2022 Ukraine invasion served as a stark reminder. Europe was forced into a costly pivot away from Russian energy. It had to align with the U.S. goal of isolating Moscow. The EU has committed over €140 billion to support Ukraine and mitigate the crisis’s effects. This shows commitment, but also its entanglement in a conflict where the U.S. is the primary strategic driver.
The illusion of strategic autonomy
Of course, the narrative of dependency is not universally accepted in Brussels. Proponents of “strategic autonomy” point to modest progress. Initiatives like PESCO have launched dozens of collaborative defence projects. The European Defence Fund now co-finances R&D. The goal is a more integrated continental defence industry.
These efforts are commendable. But they do not constitute a credible alternative to the American security guarantee. The combined military capacity of EU members remains fragmented. It falls short of what is needed to manage a major conflict alone. The war in Ukraine has brutally exposed these shortfalls. Europe relies heavily on the U.S. for intelligence, strategic airlift, and advanced munitions. The ambition for geopolitical autonomy is real. The capacity is not.
The Trump effect and the Biden continuum
Donald Trump’s previous presidency was less an aberration than an acceleration. His “America First” rhetoric shocked European leaders, but his core complaints were hardly novel. He tore up the Iran nuclear deal—a pact Europeans had painstakingly negotiated—reminding them that American protection came with strings attached.
Joe Biden’s election briefly reassured Europe. The tone softened, the language of “allies” and “partners” returned. Yet little changed in substance. Washington still set the strategic course on China, Russia, and energy. Europe’s task was to follow, adapt, and pay. The continent’s limited geopolitical autonomy was not an insult but a structural reality: Europe had outsourced sovereignty long ago.
Now, with Trump’s return to power, the dependency is not just transactional but deeply personal. Haunted by Barack Obama’s Nobel Peace Prize, Trump covets his own place in history. This hunger drives him to force rapid, theatrical “peace” settlements—Ukraine first among them. For Europe, that means financing a $90–100 billion spree of American arms purchases and absorbing compromises shaped to suit Trump’s legacy, not Europe’s long-term security. The continent remains a stage prop in Washington’s political theater, compelled to bankroll the script.
An enduring reality
This leaves the continent in a familiar position. A federal state with a unified military remains a distant dream. Eastern European states, instinctively more Atlanticist, only complicate the equation. European leaders, therefore, do what they must. They travel to Washington to manage the relationship and secure a seat at the table, even if it is not at its head. This is not humiliation; it is pragmatism.
Until it can stand alone in the field of power, Europe can talk of sovereignty, but it remains on the leash of the American eagle. The question, then, is this: Can the crisis in Ukraine become the spark for genuine geopolitical autonomy? Or will it merely confirm, once again, the profound weight of dependency?
