When Donald Trump assumed office for the second time as President of the United States, the global order was already facing a crisis of confidence. After years of war in Ukraine and political upheaval within the European Union, Europe has become exhausted and fragmented in its foreign policy positions. China is systematically expanding its economic and technological influence, while the United States is becoming increasingly divided over its role in the world. Russia, despite sanctions, economic decline, and military losses, remains determined to maintain its status as a power influencing the security architecture of Europe. Under these circumstances, transatlantic relations have become tense and uncertain. Few, however, anticipated that Greenland, a territory under Danish sovereignty, would become a symbol of this division and a potential point for a crisis within NATO.
Trump’s fixation on Greenland is not new. Even during his first term, in 2019, he attempted to “buy” the island from Denmark, which led to a diplomatic scandal and ridicule. Today, however, the situation is neither comic nor merely symbolic. This time, the idea is supported by concrete actions, political momentum, and a willingness to impose a new reality by force. In January, Trump declared that the United States must “secure full control of Greenland,” describing it as a “strategic imperative” and a “primary national interest.” At the same time, he threatened European countries with tariffs of up to 25% if they did not stop “the blocking of the American initiative.”
This is not an isolated incident. It demonstrates the essence of Trump’s foreign policy—crude, unilateral, and based on the logic of force rather than alliance. This is precisely where the root of the crisis lies, now threatening to undermine the very idea of NATO.
Greenland is not an ordinary territory. In legal and political terms, it is part of the Kingdom of Denmark and, therefore, within NATO’s territorial framework. An attack on Greenland, or even economic or military-strategic pressure, is not an attack on a “distant island,” but on the sovereignty of a founding state of the Alliance. In such a case, Article 5 of the Washington Treaty—the foundation of collective defense—would become meaningless. How would NATO respond if the aggressor were one of its own founders? If the United States, which guarantees the security of European countries, becomes a force to be defended against, the entire logic of the Alliance would collapse instantly.
This is what worries European capitals today more than any external threat. European leaders fear not Russian bombers, but that American unilateralism could destroy the basic principle that has kept Europe at peace for several generations: the belief that common defense truly means common defense. Danish Prime Minister Mette Frederiksen stated it without diplomatic restraint: “If America used force against Greenland, NATO would cease to exist.” That is not a dramatic phrase; it is a precise political diagnosis.
Trump, however, views alliances as transactions. From his perspective, allies are not partners, but rather recipients of American protection, for which they must bear a price. When that price is not enough, he turns them into targets. Greenland, in this logic, is simply a geographical projection of the same paradigm—a territory that “makes sense” only if it is under the American flag. Such a mindset does not recognize the concept of collective defense; it recognizes only a hierarchy of power.
That is why much more is at stake in this conflict than Greenland itself. The entire architecture of international relations on which the postwar world rests is at risk. If America pursues territorial appropriation in the name of “strategic necessity,” how is that different from what Russia did in Crimea? If international law is applied selectively, where does the boundary between the West and the authoritarian powers it accuses of destroying order lie?
At this moment, Europe is forced to confront what it has avoided for decades: its security cannot rest forever on the American guarantee. NATO is, at best, an alliance of equals; at worst, a front for American hegemony. Trump’s policy of expanding territorial control through economic and political blackmail clearly shows that the United States has moved away from the Alliance’s value base. It is no longer an alliance of ideas but a marketplace of power.
However, the deepest dimension of this crisis is not military but civilizational. Since 1949, NATO has been more than a defense treaty; it has been the framework of the West’s moral unity. It was a guarantee that democratic forces would not attack each other, that there was a line between political interest and fundamental principle. If that line is erased, if America turns against a country whose soldiers have fought alongside Americans from Normandy to Helmand, then not only does the alliance break—the idea of the West breaks.
Trump, however, is not the cause but the symptom. He does not invent a new world; he only reflects its essence: a world in which collective defense has become mere rhetoric and power is the only language of politics. Europe, weary of crises and internal divisions, now faces a question it has suppressed for decades: what if America is no longer a reliable ally, but an unpredictable force?
In this context, Greenland becomes a reflection of a broader power shift. Its strategic importance—control of the Arctic, new trade routes, energy, and mineral resources—is just the beginning. The fundamental issue is political: the Arctic now serves as a boundary between multilateralism’s struggle for survival and the growing dominance of unilateralism. When Trump refers to Greenland as “America’s natural sphere of influence,” he is not just talking about the Arctic. He is describing a world in which “sphere of influence” once again becomes a legitimate concept.
The European response, though strong in diplomatic tone, remains uncertain in action. Brussels, Berlin, Paris, and London—they know that direct conflict with Washington would be political suicide, but also that silence means acceptance. This is why European capitals are adopting a new strategic language—the language of “strategic autonomy.” Greenland acts as a catalyst in this regard. It is forcing Europe to realize that the era of the American guarantee is over and that it must learn to see itself as a security subject, not merely an object.
For Trump, however, it is precisely this European push for independence that poses a threat. His vision of NATO is not a community but a chain of dependence. If Europe were to disengage from American strategy, American dominance over the Western order would collapse. This is why he employs aggressive rhetoric and exerts economic pressure. Greenland, though symbolic, becomes the place where the struggle between the old and new West is most direct.
In this situation, Russia and China do not need to take any action. Trump’s approach is already working in their favor. Every crack in NATO, every doubt about Article 5, and every diplomatic quarrel within the Alliance means less cohesion and greater freedom of action for authoritarian powers. In Moscow, Putin watches with cynical satisfaction; in Beijing, Xi Jinping sees confirmation that the liberal order is crumbling from within, without a single shot fired.
Trump, although he claims otherwise publicly, probably does not fully recognize Greenland as a tool for Russian or Chinese interests. But objectively, it is. If the US undermines the territorial integrity of a NATO member, the West ceases to exist as a political idea. NATO, stripped of moral credibility, becomes an impotent military administration without purpose or effect. Europe, forced to choose between blind alliance and autonomy, begins to fracture.
The irony is that Trump, in trying to cement America’s global dominance, may actually undermine the very structure that makes that dominance possible. Without NATO, the United States would lack the global political and military reach that makes it a world power. With no real power to shape events in Europe, the Middle East, or Asia, its influence would remain limited to the Western Hemisphere. Without Europe as a political and moral partner, American power becomes purely military, lacking the soft power that gave it legitimacy.
Greenland, in this respect, is not the end of the world but the beginning of a new understanding of it. On its icy shores, two paradigms collide—the world of collective security and the world of raw power. The outcome of that collision is not measured by territory but by values: will the international order remain based on law and trust, or will it devolve into an endless chain of coercion in which even allies are not safe from their own allies?
If America continues on the path Trump has set, NATO will not collapse from external pressure but from within—the moment its most powerful member stops believing in its own rules. Then everything on which the West was built—shared values, solidarity, and respect for international law—will lose its real meaning and remain only a memory of a period that ended without a clear legacy.
