At the close of the World War II, the world did not find peace so much as it found structure. Two opposing security architectures emerged from the ruins of Europe: the Western alliance institutionalised in North Atlantic Treaty Organization, and the Eastern bloc consolidated under the Warsaw Pact. These were not mere military alliances; they were ideological fortresses, each defining the limits of sovereignty within their spheres.
From the outset, cracks existed beneath the surface of both blocs. In Western Europe, not every nation was comfortable outsourcing its ultimate security to Washington. France, under Charles de Gaulle, pursued an independent nuclear deterrent—force de frappe—a quiet declaration that sovereignty, especially nuclear sovereignty, could not be subcontracted indefinitely.
In the East, dissent was far more dangerous. The Prague Spring represented an attempt by Czechoslovakia to carve out political autonomy within Soviet constraints. Moscow’s response was swift and brutal: tanks, not tolerance. It was a clear signal that independence within the Warsaw Pact would not be negotiated—it would be crushed.
The collapse of the Fall of the Berlin Wall marked not just the end of division in Germany, but the unraveling of the Soviet security order. The Warsaw Pact dissolved soon after, and with it, the bipolar certainty that had defined global politics for decades. Yet instead of dissolving alongside its adversary, NATO expanded—eastward, steadily, and provocatively.
To the West, this expansion was framed as stabilisation. To Russia, it was something else entirely: encroachment. A strategic tightening of the noose. The seeds of present tensions were planted not in a moment, but in a pattern.
NATO has long insisted it is a defensive alliance. Yet its record complicates that narrative. Its interventions during the Yugoslav Wars and later in Libya intervention blurred the line between defence and projection of power. These actions raised uncomfortable but necessary questions: is NATO a shield, or is it also a sword?
Ironically, the only time NATO’s foundational principle—collective defence under Article 5—was invoked came after the September 11 attacks. In response, allies rallied behind the United States in military campaigns in Afghanistan and Iraq. Even here, unity came at a cost, as the legitimacy and outcomes of those wars remain deeply contested.
Enter Donald Trump. Where previous American presidents treated NATO as a strategic instrument of influence, Trump reframed it in transactional terms. His demand was blunt: pay more, or risk abandonment. Defence spending targets—2% of GDP—became less a guideline and more a toll. Unsurprisingly, much of this increased spending flowed back into the coffers of the American military-industrial complex.
But Trump’s approach did not stop at financial pressure. He expanded expectations of loyalty into geopolitical compliance. Calls for allied support in potential conflicts with Iran, alongside his controversial interest in acquiring Greenland, unsettled even the most loyal NATO partners. These were not the actions of a steward of alliances; they resembled those of a proprietor testing the limits of ownership.
Now, the unthinkable is being said aloud: that the United States might withdraw from NATO altogether.
For Europe, this is not merely a diplomatic inconvenience—it is an existential reckoning. For years, the idea of an independent European defence capability was debated, often resisted. The United Kingdom, even as a member of the European Union, acted as a brake on deeper military integration, arguing that it would undermine NATO cohesion.
In retrospect, that resistance may have been strategically short-sighted.
Today, the logic is shifting. Europe is beginning to recognise that its security interests may no longer align perfectly with Washington’s unpredictability. The prospect of a “Euro force” is no longer theoretical—it is becoming necessary. With France’s independent nuclear capability as a potential cornerstone, Europe has the latent capacity to construct its own deterrence architecture.
If such a transition occurs, the implications would be profound. The unipolar moment of American dominance would give way to a more distributed balance of power: the United States, China, Europe, and Russia as competing centres of influence.
In that world, the United States would not disappear—but it would be diminished.
And perhaps, from another perspective, normalised.
There is also a paradox worth confronting. NATO’s continued existence after the Cold War has long been a source of grievance for Russia—a symbol of its defeat and exclusion. If NATO were to dissolve or fragment, it might remove a persistent irritant in East-West relations. Russia would no longer feel like a vanquished power being encircled, its geopolitical “nose rubbed in defeat,” as some would put it.
But such an outcome would not necessarily produce stability. Power vacuums rarely remain empty.
What is clear, however, is this: Trump’s approach to alliances may achieve what decades of adversaries could not. Not through confrontation, but through corrosion. Not by attacking NATO from without, but by hollowing it from within.
In the end, the question is no longer whether NATO will change. It is whether it will survive the change at all—and what kind of world will emerge in its absence.
