The silence from Brussels and London has been deafening.
As President Trump openly muses about acquiring Greenland—including by force—European leaders have responded with little more than diplomatic throat-clearing and carefully worded statements of concern. This timidity is not statesmanship. It is abdication.
Let us be blunt: Greenland is European territory. It is an autonomous region of Denmark, a NATO ally, an EU-associated territory. Any attempt to take it by force would be an act of war against a European nation. That this even requires stating reveals how far European powers have allowed themselves to be diminished in American eyes.
The EU and the UK have seemingly forgotten what they are. These are nations and institutions that predate the American experiment by centuries—in some cases, by millennia. Rome rose and fell before English common law was codified. The Treaty of Westphalia established the modern international order while America was still a collection of colonies. Europe has survived plagues, world wars, occupations, and the collapse of empires. It will survive a trade dispute with Washington.
The same cannot be said in reverse.
Europe is not without weapons in an economic conflict—and they are far more potent than Washington seems to appreciate.
Consider pharmaceuticals. European companies supply a staggering portion of America's medicines. Novo Nordisk, Sanofi, AstraZeneca, Roche, Bayer—these names are not optional for American patients. An export restriction on critical medications would create a healthcare crisis within weeks. The United States simply does not have the domestic capacity to replace these supplies.
Then there is aerospace. Airbus delivers roughly half of all commercial aircraft purchased by American carriers. Boeing cannot meet domestic demand alone, as its ongoing production disasters have made painfully clear. European aviation authorities could slow-walk certifications, delay deliveries, or restrict parts supplies. American airlines would feel the pinch immediately.
Financial services offer another pressure point. London remains a global financial hub despite Brexit. European banks hold substantial American assets and conduct enormous daily transaction volumes with US counterparts. Regulatory friction, transaction delays, or capital requirements could introduce chaos into markets that depend on seamless transatlantic flows.
Luxury goods, automobiles, specialty chemicals, precision machinery, wine and spirits, fashion—the list continues. Europe exports goods America's wealthy and middle class have grown accustomed to. Tariffs work both ways, and European consumers can find alternatives for American products far more easily than Americans can replace a BMW, a bottle of Bordeaux, or a course of medication.
And then there is the nuclear option: the US dollar's reserve currency status depends in part on European cooperation. If the EU began conducting more trade in euros, requiring euro settlement for energy purchases, or coordinating with other blocs to reduce dollar dependence, the long-term consequences for American economic hegemony would be severe. This would not happen overnight, but the mere credible threat of movement in this direction should give Washington pause.
The consequences of a genuine EU-US economic rupture would be asymmetric—and not in America's favor.
American consumers would face immediate price shocks. Goods that currently flow freely across the Atlantic would become scarce or expensive. Pharmaceutical shortages would strain an already fragile healthcare system. Automotive supply chains would seize. Technology companies dependent on European components, software, and talent would scramble.
American farmers, already battered by previous trade wars, would lose one of their largest export markets. Soybeans, pork, poultry, and agricultural machinery would stack up in warehouses while European buyers turned to Brazil, Argentina, and domestic producers.
The financial sector would face regulatory balkanization. American banks operating in Europe would confront new compliance burdens. Investment flows would slow. The certainty that has underpinned transatlantic commerce for decades would evaporate.
Perhaps most critically, American diplomatic isolation would accelerate. If Washington demonstrates it is willing to bully its closest allies, why would any nation trust American commitments? The soft power that has been America's greatest asset since 1945 would erode further, pushing more countries toward Beijing's orbit—precisely the outcome American strategists claim to fear most.
Some will argue that European resistance to American pressure would harm Ukraine. This concern deserves acknowledgment—and a clear-eyed response.
Yes, American military aid has been critical to Ukraine's defense. Yes, a rupture in transatlantic relations could complicate the flow of weapons and intelligence. Yes, Kyiv would suffer if its two largest backers turned on each other.
But let us be absolutely clear about where responsibility would lie: with Washington.
Europe has already demonstrated its commitment to Ukraine. The EU has provided tens of billions in financial assistance, welcomed millions of refugees, imposed sweeping sanctions on Russia, and begun the long process of integrating Ukraine into European structures. This support would continue—and likely intensify—regardless of American posturing. If anything, American abandonment would accelerate European defense integration and military investment, ultimately producing a more capable and self-reliant European security architecture.
If Ukraine suffers because the United States chose to bully its allies rather than work with them, that is an American failure, not a European one. Europe did not pick this fight. Europe is not threatening to seize allied territory. Europe is not issuing ultimatums and demanding policy changes under threat of economic warfare.
Washington wants to play the bully and then blame Europe for the consequences? That narrative must be rejected categorically. The EU and UK should make clear: we will defend Ukraine, we will defend ourselves, and we will not be blackmailed. If the transatlantic relationship fractures, history will record who swung the hammer.
The United States depends on global supply chains for everything from pharmaceuticals to rare earth minerals, consumer electronics to industrial machinery. American manufacturing has been hollowed out over decades of offshoring. The country runs persistent trade deficits precisely because it cannot produce what it consumes. Europe, by contrast, maintains robust manufacturing bases, agricultural self-sufficiency in key sectors, and—critically—the institutional knowledge to rebuild what has atrophied.
Yes, a genuine economic rupture with America would be painful. Germany would need to revive its defense industrial base. European nations would need to accelerate military integration and spending. Supply chains would require restructuring. None of this would be pleasant or cheap.
But Europe would adapt. It always has.
The deeper issue is not economic arithmetic. It is the fundamental question of sovereignty. When the United States threatens to withdraw support unless European nations adopt particular policies—whether on trade, technology, or anything else—it is not behaving as an ally. It is behaving as a suzerain issuing commands to vassal states.
This must end.
European leaders need to communicate, clearly and publicly, that the transatlantic relationship is a partnership of equals or it is nothing. The United States does not dictate European trade policy. It does not dictate European environmental regulations. It does not dictate which nations Europe may conduct commerce with. And it absolutely does not get to annex European territory through threats or force.
If Washington wishes to play hardball, Brussels and London should be prepared to respond in kind. The tools exist. The leverage exists. The only question is whether European leaders have the spine to use them.
The current moment calls for steel, not silk. European leaders must remind Washington of a simple truth: alliances are built on mutual respect, not submission. The United States is not in charge of the world. It does not write the laws of other nations. And if it wishes to remain a partner rather than become an adversary, it would do well to remember that Europe has options—and the will to use them.
The only question is whether European leaders have the courage to say so.
