The Illusion of National Sovereignty
In a world of continental powers, the nation-state is too small to decide the things that matter most.
In October 1956, the Hungarian government announced that it was withdrawing from the Warsaw Pact and declaring neutrality. It was a sovereign decision, taken by a legitimate government in response to a popular uprising that had shaken the country for days. The announcement was broadcast on national radio. The prime minister, Imre Nagy, appealed to the United Nations and to the Western powers for recognition and support.
Four days later, Soviet tanks entered Budapest. Within two weeks, the uprising was crushed, the government dissolved, and Nagy under arrest. He was executed two years later.
Hungary in 1956 was formally sovereign. It had a government, a territory, a seat at the United Nations, and a head of state making decisions in the name of the Hungarian people. What it did not have was the capacity to make those decisions stick. The formal apparatus of sovereignty was intact. The effective capacity was nonexistent. And when the two came apart, it was the capacity that determined the outcome, not the form.
Hungary is an extreme case, chosen because it is clear. But the structure of the problem it illustrates is not extreme at all. It is the normal condition of medium-sized states in the contemporary world, experienced not through Soviet tanks but through the quieter mechanisms of economic dependency, technological exposure, and strategic irrelevance.
The Century That Changed the Scale of Power
For most of the history of the modern state system, a determined middle power could sustain meaningful sovereignty. The Peace of Westphalia in 1648 created a system of sovereign states in which a country of several million people, with a competent army, a functioning economy, and skilled diplomacy, could genuinely set its own course. Prussia did it. Sweden did it. The Netherlands did it. The scale of economic and military competition was such that a state of moderate size could compete at the relevant level.
That world ended in the twentieth century.
The First World War revealed that industrial-scale warfare required industrial-scale economies. The states that could sustain the war were the states with the largest industrial bases: Britain, France, Germany, the United States, and Russia. Smaller powers participated, suffered, and largely did what the great powers required of them.
The Second World War accelerated this dynamic. The winning coalition was built around an economy, the American one, that produced roughly half of all global industrial output by 1945. The atomic bomb, developed at a cost that only the United States could sustain at the time, immediately redefined what security required at the frontier. A state that could not develop or acquire nuclear weapons was permanently exposed to states that could.
The Cold War then organized the entire international system around two poles of such overwhelming power that every other state was, in the relevant strategic sense, a secondary actor. The question for most states was not what they would do but which great power they would align with and on what terms.
What emerged from this century of compressed change was a new threshold for effective sovereignty, one set not by the costs of seventeenth-century warfare but by the costs of maintaining a competitive position in a world of continental-scale powers and global-scale economic competition. That threshold is, for a single nation-state of ordinary size, no longer reachable.
The Three Domains Where Sovereignty Has Migrated
The argument that individual sovereignty is increasingly illusory is not primarily about military power, though military power matters. It operates across three domains that together define the effective range of state action in the contemporary world.
The first domain is security. A state that cannot defend its own territory without a foreign security guarantee is not making autonomous security decisions. It is dependent on the decision of its patron to honor the guarantee, which is a decision the patron makes on the basis of its own interests, not the protected state’s. NATO’s Article 5 has functioned as a genuine deterrent for seven decades. But its credibility has always rested on American willingness to treat an attack on a member as an attack on the United States, and that willingness is a political judgment made in Washington, not a mechanical obligation. The European states that rely on this guarantee are not sovereign in their security in the same way that a state capable of independent deterrence is sovereign. They have chosen a form of managed dependence, which is a rational choice given their individual capabilities. But it is managed dependence, not independence.
The second domain is economics. The rules that govern global trade, investment, and finance are not made by states equally. They are made, predominantly, by the largest economic actors: the United States, the European Union, and increasingly China. Standards for financial regulation, data governance, pharmaceutical approvals, technology compatibility, and trade in services are set in Washington, Brussels, and Beijing and then applied to everyone else. A medium-sized state outside these centers of rule-making is not setting the terms of its economic life. It is receiving them.
The third domain is technology. This is the newest and in some ways the most consequential dimension of the sovereignty problem. The critical technologies of the contemporary economy, semiconductors, artificial intelligence systems, advanced communications infrastructure, biotechnology, are produced by a tiny number of firms concentrated in a tiny number of countries. A state that cannot produce these technologies, or that depends on a single foreign supplier for them, has a structural vulnerability that no amount of diplomatic agility can fully compensate. When the United States restricted the export of advanced semiconductors to China in 2022, it demonstrated in plain terms what technological dependency means: the ability of one state to constrain the economic and military development of another without firing a single shot.
The Nationalist Temptation
Against this analysis, a familiar argument reappears in the politics of almost every country: that sovereignty can be recovered by asserting it more forcefully, by withdrawing from constraining international arrangements, by prioritizing national production and national decision-making over global integration.
The argument has genuine appeal because it identifies a real problem. The constraints on national sovereignty are real. The loss of effective control over economic policy, technological development, and security arrangements is real. The frustration that produces nationalist political movements is not invented.
What the argument gets wrong is the remedy. Withdrawing from collective arrangements does not restore effective sovereignty. It removes the formal constraints while leaving the structural ones intact, and often makes them worse. A state that leaves a trade bloc still operates in a global economy whose rules it did not write and cannot change alone. A state that withdraws from a security alliance still faces the military capabilities of states that have not withdrawn from theirs. A state that rejects international technology standards still depends on technologies it cannot produce independently.
The nationalist remedy for lost sovereignty mistakes the symptom for the cause. The formal constraints of international institutions are not what limits national sovereignty. What limits national sovereignty is the structural reality that the scale of contemporary economic and military competition has moved beyond what individual nation-states of ordinary size can match. Removing the formal constraints while leaving the structural reality unchanged does not produce more sovereignty. It produces less, combined with the illusion of more, which is more dangerous.
Why Collective Sovereignty Is Not a Contradiction
If individual sovereignty is structurally insufficient for most states, and if asserting it more forcefully does not solve the underlying problem, then the question becomes whether collective arrangements can genuinely produce the effective sovereignty that individual states cannot sustain alone.
The answer is yes, but only under conditions that are more demanding than they appear. Not every collective arrangement produces effective collective sovereignty. Many produce only the form of it, the shared institutions, the common declarations, the ceremonial solidarity, without the substance: the genuine pooling of capacity that allows the collective actor to do things its members cannot do independently.
The difference between a collective arrangement that produces real sovereignty and one that produces only its appearance is not a matter of institutional design alone. It is a matter of the underlying conditions that make collective action coherent over time. Those conditions are the subject of the analysis that follows throughout this project. But the starting point is recognizing that the alternative to collective sovereignty is not national sovereignty. The alternative is the condition Hungary found itself in on November 4, 1956: formally sovereign, actually powerless, at the mercy of forces it could neither resist nor influence.
The Uncomfortable Arithmetic
There is a way to make this argument concrete that cuts through most of the political noise around it.
The European Union’s single market is the largest economic bloc in the world by some measures. When the EU sets a product standard, every company that wants to sell into that market must comply, regardless of where it is headquartered. This is sometimes called the Brussels Effect: the practical export of regulatory power to states that had no vote in writing the rules. A medium-sized state outside the EU still has its Brussels Effect applied to it. It simply has no seat at the table when the rules are being written.
The question for every medium-sized state contemplating its relationship to larger collective arrangements is therefore not whether it will be subject to the decisions of larger powers. It will be, regardless of what it decides about formal membership. The question is whether it will be subject to those decisions as a participant with voice and vote, or as an outsider without either.
That is the uncomfortable arithmetic of sovereignty in the contemporary world. It does not resolve every question about how collective arrangements should be structured, or which ones deserve the commitment they demand. But it does clarify what is actually at stake.
The nation-state is not obsolete. But it is, for most states, insufficient. The choice is not between sovereignty and its surrender. It is between different strategies for maximizing effective capacity in a world where the threshold for genuine self-determination has risen beyond what most states can reach alone.
Imre Nagy understood what sovereignty required when it was too late to act on that understanding. The lesson is available to everyone. Not everyone is taking it.
