Poland’s Break With NATO Raises A Difficult Question: What Comes Next?

There is a moment in the life of any institution when its defining contradiction becomes impossible to ignore. The contradiction does not appear all at once. It accumulates slowly, like water behind a dam, and then one day a small, concrete event makes visible what had been hiding in plain sight for years. For NATO, that moment arrived when Poland said no.

The sequence of events deserves to be told plainly, because its logic is devastating. Iran, through no fault of Turkey’s, targeted a NATO member state with multiple ballistic missile attacks. Turkey, a dues-paying, treaty-bound member of the North Atlantic Alliance, turned to a fellow member for help. It asked Poland to provide a single Patriot air defense battery on a temporary basis, for the straightforward purpose of protecting Turkish civilians and territory from a foreign nation’s missiles. Poland refused.

The United States intervened diplomatically. Washington took up Turkey’s case directly and asked Poland to reconsider. Poland refused again. Consider what that second refusal means. The United States stations 10,000 of its own troops in Poland, positioned roughly 50 miles from Russian territory. Those soldiers are accompanied by 170 Abrams tanks, hundreds of Bradley fighting vehicles, F-16s, F-15s, and periodic deployments of F-35s. American forces in Poland are not a symbolic gesture. They are a tripwire, and everyone in Warsaw knows it. If Russia attacked Poland, it would not merely be attacking a NATO member. It would be attacking American soldiers, which means it would be at war with the United States of America. That guarantee, backed by American blood and treasure, is the single most powerful deterrent Poland possesses. It dwarfs anything in the Polish inventory, including the Patriot batteries Poland chose to keep for itself rather than temporarily share with an ally under fire.

Poland’s calculus was, in a narrow tactical sense, understandable. Nations protect their own. But the moral logic is unsustainable when the nation making that calculation is itself protected entirely by the soldiers of the country it just refused. The American people send their sons and daughters to stand watch on Polish soil, a few dozen miles from a hostile border, so that Polish families can sleep safely. When Poland looked at that arrangement and decided it still could not lend a single missile battery to a NATO ally in distress, it communicated something important about what it believes the alliance actually is. It believes NATO is a service it receives, not a covenant it upholds.

Dwight Eisenhower saw this coming. In 1951, as Supreme Allied Commander Europe, he said something that deserves to be quoted in full: “If in 10 years, all American troops stationed in Europe have not been returned to the US, then this whole project will have failed. We must get these people to stand on their own feet militarily.” That was 74 years ago. The troops are still there. Europe never stood on its own feet. And the institution Eisenhower was warning about has now produced a moment in which a member nation simultaneously refuses to assist a treaty ally under missile attack and pockets the full security guarantee provided by the country that made the request. Eisenhower was not a peacenik or an isolationist. He was a man who understood that permanent dependency corrupts alliances and that a security guarantee with no reciprocal obligation is not an alliance at all. It is a protectorate. And protectorates, sooner or later, produce exactly the kind of ingratitude Poland just displayed.

The cost of this arrangement is not abstract. American taxpayers spend approximately $20B per year maintaining the US military presence in Europe. That figure includes installation operations and sustainment, military construction, the European Deterrence Initiative, and the overseas stationing premium, the measurable additional cost of keeping troops in Europe rather than at home. Since the beginning of the Cold War, the inflation-adjusted total approaches $2T. Two trillion dollars. Spent on a continent whose combined GDP dwarfs Russia’s, whose population exceeds America’s, and whose collective wealth is more than sufficient to fund a credible conventional deterrent without a single American soldier. A 2025 analysis found that Europe could provide for its own conventional defense with an investment of approximately €250B per year, roughly 1.5% of EU GDP, if its members coordinated effectively. Europe has chosen, year after year, not to make that investment, precisely because the United States has made it unnecessary. This is what economists call moral hazard. When someone else bears the cost of your risk, you take more of it.

Poland’s refusal is the sharpest recent expression of this dynamic, but it is not the only one. Across the continent, NATO members and European nations are quietly, and in some cases not so quietly, restricting U.S. access to military bases and assets that American taxpayers have funded and American service members have maintained for decades. Spain, Italy, France, Switzerland, and to a meaningful degree the United Kingdom have all placed constraints on American use of installations within their borders. The precise contours vary by country and by contingency, but the pattern is consistent: when the United States needs to act, the hosts hedge. When the United States asks for cooperation, the hosts calculate their own political interests first.

This is a profound problem, and not merely a diplomatic one. The strategic case for forward basing in Europe rests on the argument that those bases provide rapid response capability, logistics depth, and political signaling that deters adversaries and reassures allies. Every one of those justifications depends on the bases actually being available when the United States needs them. A base you cannot use in a crisis is not a military asset. It is a liability, because it still costs money, still requires personnel, and still creates the political entanglements that come with any forward presence, while providing none of the operational benefits that supposedly justify the expense. The Government Accountability Office has repeatedly documented the absence of complete, consistent posture-cost accounting in U.S. military planning for Europe. The American people are paying an enormous bill without a reliable ledger. And increasingly, they are paying that bill for installations that allied governments will not let them use freely.

The strategic picture is not symmetrical. The United States faces genuine defense requirements across multiple theaters simultaneously. The Indo-Pacific demands growing attention and resources. Homeland defense requirements are not shrinking. And the marginal dollar of defense spending directed toward a wealthy European theater where allies refuse to bear their fair share is a marginal dollar not available for higher-priority commitments. The Congressional Budget Office estimated that maintaining approximately 56,000 Army forces in Germany alone cost about $1B more per year than stationing those same forces in the United States. Scale that premium across the full European presence, now estimated near 100,000 troops in the post-2022 surge, and the number grows considerably. That is money that could fund platforms, readiness, and capabilities in theaters where American allies are more willing to reciprocate and where adversaries are less deterred by current posture.

None of this is an argument for abandoning Europe to Russian aggression. The deterrence function of U.S. presence is real, and NATO, when it has functioned as designed, has served American interests by preventing a third European war from developing on a continent where two world wars cost millions of American lives. The argument is different and more specific. It is that the current arrangement, in which the United States provides a near-unconditional security guarantee, maintains an enormous forward presence at enormous cost, and receives in return a pattern of free-riding, access restrictions, and outright refusals of the kind Poland just demonstrated, is not sustainable as a matter of either fiscal prudence or alliance integrity.

An alliance that operates this way is not really an alliance. The word “alliance” implies mutual obligation. It implies that when one member is struck by ballistic missiles, the others will set aside parochial calculations and help. It implies that when the country providing the ultimate security guarantee makes a reasonable request, the beneficiaries of that guarantee will take the request seriously. Poland’s refusal, replicated across the continent in various forms, reveals an institution that has become comfortable with consuming American protection while declining to extend equivalent solidarity in return. The Turkey-Poland episode is the canary in the coal mine. The air in that mine has been thin for some time.

Eisenhower’s warning was precise. He did not say NATO would fail because of Russian aggression or because the alliance lacked military capability. He said it would fail if European members never stood on their own feet militarily. That is exactly what happened. Europe leaned on the American commitment, spent its defense dollars elsewhere, and built political cultures that treated security as something the United States would always provide. The warning expired long ago. What Poland’s refusal provides is not a prediction but a diagnosis. The patient is not in the early stages of an illness that might be reversed with the right prescription. The patient has been declining for decades, and the Poland episode is simply the clearest recent evidence of what the decline looks like in practice.

The American people deserve a serious accounting of what they are receiving for $20B a year and $2T since Harry Truman signed the North Atlantic Treaty. Here is the central irony of the alliance they funded: the presence of American troops across Europe meant that Russia never had to wonder whether NATO would hold together if it attacked. It would not merely be attacking Germany or Poland or the Baltic states. It would be attacking American soldiers from the moment the first shell landed. That was the tripwire. That certainty, not the Article 5 text, not the Brussels communiques, not the summit declarations, is what kept the peace for 75 years. Russia did not need to calculate whether the US would eventually join the fight as it had in the First and Second World Wars, arriving late and tipping the balance. American forces would already be in the fight when it started. That is the most powerful deterrent in the history of military statecraft, and it is the thing Europe is now casually placing at risk by calling for American troops to leave Germany and other host nations and by restricting access to installations the United States has maintained at enormous expense. The strategic recklessness of that position is almost impossible to overstate.

And yet the legal architecture of the alliance was always thinner than its rhetoric suggested. Most people who invoke NATO’s collective defense commitment do not know what Article 6 actually says. It does not require member states to come to the aid of an attacked ally with military force. Poland’s refusal to share a single Patriot battery with Turkey demonstrated this with perfect clarity. Each member decides for itself how to respond to an attack on another member. That response could be troops. It could be humanitarian aid. It could, in the most cynical reading of the treaty’s plain language, be nothing more than a formal expression of concern. The guarantee that made NATO feel like a real alliance was never the treaty text. It was the physical presence of American soldiers on European soil. Remove that presence, and you discover what the alliance actually is, which is a framework that allows each member to calculate its own interests while sheltering under an American umbrella. NATO was, in a meaningful sense, a polite fiction that made Europe comfortable with the arrangement of allowing the United States to bear the primary burden of its defense. The fiction served a purpose. But fictions have a cost when they are mistaken for facts.

The timeline ahead sharpens the question considerably. A senior French Air Force commander warned this week that Russia will likely test NATO’s resolve in 2028 and 2029. If that assessment is correct, Europe has two or three years to decide whether it intends to defend itself or whether it intends once again to depend on American soldiers to do it. Given the pattern of the last seven decades, the answer is not difficult to predict. But the American people are entitled to make their own calculation. We can preserve NATO in name. The acronym can survive. The headquarters in Brussels can remain open. The annual summits can continue producing their communiques. But the honest truth is that if Russia moves against a European member in 2028 or 2029, it will fall to whoever occupies the White House at that moment to decide, with no binding legal obligation forcing the answer, whether to commit American lives and treasure to a continent that spent a generation free-riding on American protection and then, when asked to share one missile battery with an ally under fire, said no. If Europe wants to go it alone, America should let it. Bring the troops home. Save the $20B a year. And let the Europeans discover, at last, what standing on their own feet actually requires. Eisenhower knew the answer in 1951. It has taken the rest of us 74 years to catch up.
