There is something richly instructive about the spectacle of King Charles III standing before a joint session of the United States Congress on the occasion of America's 250th anniversary, urging Americans not to become "more inward-looking" and extolling the architecture of NATO.
Charles, as it happens, is the great-great-great-great-grandson of King George III — the very monarch against whose accumulated abuses, distant tyrannies, and taxation without the consent of the governed the colonists took up arms in 1776. The men who gathered in Philadelphia that summer did not cite global obligations, multilateral frameworks, or the dangers of excessive national self-interest when they composed the document that gave birth to this republic. They cited the rights of man, the consent of the governed, and what they called — carefully, historically — a long train of abuses that made separation not merely justified but morally necessary.
The republic they founded was not, at its core, an internationalist project. It was a sovereign one.
None of this is to say that Charles meant ill. His visit appears to have been conducted with genuine warmth and goodwill. The relationship between the United States and the United Kingdom is one of the most durable and genuinely reciprocal alliances in modern history, built across two world wars, a Cold War, and decades of shared intelligence cooperation. The king's speech yielded high attendance and bipartisan support from lawmakers — an increasingly rare occurrence in a chamber more accustomed to partisan theater. None of that is in dispute.
What is worth examining is the assumption embedded in his counsel.
Thucydides, in his account of the Melian Dialogue, understood a certain permanent dynamic: large powers tend to invoke universal interests precisely when what they seek is compliance. The Athenians told the Melians it was in everyone's interest to accept Athenian hegemony, because the alternative — a world without order — was worse. The Melians chose instead to fight for the thing that made them Melian rather than accept a peace that would have made them Athenian. They were annihilated for it. Thucydides did not present this as a triumph of reason.
When a foreign head of state — any foreign head of state, however friendly — stands before the legislature of a sovereign republic and urges that republic not to turn inward, he is, whether he intends it or not, making a claim about who gets to define American interests. The implicit argument is clear: looking inward is a failure of maturity and responsibility. Engagement with the world — on the terms familiar to the postwar liberal order, including NATO, established multilateral frameworks, and the foreign policy consensus of recent decades — represents the more civilized alternative.
But self-governance is the exercise of looking inward. It is not a failure of vision but its expression.
Tocqueville, who traveled this republic in the 1830s with an eye unclouded by flattery, observed something that remains true: the vitality of American democracy depended not on its connection to external systems but on the health of its internal ones — its local institutions, its civic associations, its churches, its habit of attending to its own affairs. His greatest warning in Democracy in America was not about military conquest. It was about soft despotism — the gradual replacement of individual and national self-determination with a benign but smothering external management. A free people, he warned, could lose their liberty not through violence but through the slow surrender of judgment to the preferences of a distant and paternalistic authority.
Washington understood this. His Farewell Address — composed by a man who had seen what permanent entanglement cost in blood — did not counsel isolation from the world. It counseled vigilance against "permanent alliances" and "passionate attachments" that would subordinate American judgment to the imperatives of others. He was not a man afraid of the world. He was a man who had just finished remaking it.
This tension — between the republic's obligations to itself and its obligations to the international order it helped construct — does not resolve neatly. NATO served a specific strategic purpose in 1949: the containment of Soviet expansion across a devastated European continent. That purpose was legitimate. The alliance performed it reasonably well, and the fall of the Berlin Wall vindicated much of its original logic. These were genuine achievements.
But the question that serious statesmen — and serious citizens — are obligated to ask is whether alliances built for one historical moment continue to reflect the actual interests of the republic in another. Whether the terms of engagement, the distribution of burdens, the chain of mutual commitment, still serve the people who ultimately pay for them. This is not hostility to allies. It is the minimum exercise of national self-governance.
It is also, as a matter of historical record, precisely the kind of question that King George III preferred his colonists not ask.
Chesterton's fence is instructive here. Before tearing down the assumption that nations have the right to define their own interests before anyone else's, one should ask why that assumption was built in the first place. The colonists of 1776 did not fight for the right to dissolve into a larger order, however enlightened. They fought for the right to govern themselves — to make their own mistakes, chart their own course, levy their own taxes, and answer to their own people before any external authority, however benevolent.
That instinct is not parochialism. It is not the province of lesser minds or darker impulses — though it has been described as such by those for whom borders have always been optional and national identity a mere accident of birth. It is the civilizational inheritance the Founders embedded in the Constitution, the permanent thing they entrusted to their posterity.
The moment deserves its celebration. America at 250 is remarkable by any honest accounting — a continental republic that absorbed wave after wave of newcomers, fought two world wars to liberate peoples it had never met, rebuilt the economies of nations it had just defeated, and extended to its own citizens liberties that most of the world's population still cannot claim. The United Kingdom was its partner in nearly all of that work. The special relationship is not a fiction. It is a living inheritance.
But partnerships between sovereign nations are most durable — and most honest — when both parties acknowledge that the other has interests of its own, obligations to its own people first, and the right to make judgments that may not align with what the other party prefers. An alliance that requires one partner to suppress its own assessments of self-interest is not a partnership. It is a dependency.
Charles meant his counsel as encouragement. History suggests the founders of this republic would have received it differently.
Two hundred and fifty years ago, a generation of Americans looked inward — at their own conscience, their own rights, their own capacity for self-government. They decided that they, not a distant throne, would determine what obligations they owed to the world.
The republic they built was the result.
On its 250th anniversary, it is worth remembering both what they built — and why.
