To the People of the State of Connecticut:

Among the first truths which must be understood by any people desirous of preserving constitutional liberty is this: that the Union which secures their common safety, their political stability, and the lawful exercise of their rights cannot be treated as a temporary convenience, but must be regarded as a permanent and essential condition of the Republic itself. It is neither a compact of convenience among sovereign nations nor a consolidated government in which the several States exist only at the pleasure of a distant national authority. It is instead one constitutional Republic, composed of States which retain meaningful authority of their own while remaining permanently joined beneath a common Constitution and within one national Union. The strength of the Union therefore depends neither upon extinguishing the constitutional authority of the States nor upon permitting that authority to become a pretext for disobedience to lawful national authority. The wisdom of this arrangement consists in its recognition that national unity and local self-government are not opposing principles, but necessary supports of the same constitutional system. A Union which demands uniformity upon every question will inevitably transform ordinary political disagreement into a contest for national supremacy.

Differences of position and political judgment are not, of themselves, injuries to national unity. Where Connecticut may adopt one view of a question, Texas may arrive at another, while California may determine that the same question requires little action at all. Such differences are not defects in the federal system, but natural consequences of allowing the several States to exercise genuine constitutional authority of their own. Nor does their existence threaten the Federal Government or render its lawful authority illegitimate. The greater danger arises from the belief that every disagreement among the States must be settled nationally by whichever faction happens, for the moment, to command the Government. The Union is strengthened, not weakened, when the States are permitted to remain States. Yet they remain States within a Union, not nations at liberty to disregard lawful national authority whenever its exercise becomes disagreeable.

When every substantial political question is removed from the States and transferred to the national arena, the ordinary disagreements of a free people acquire an importance far greater than they ought naturally to possess. If control of the Federal Government comes to determine questions of education, policing, local regulation, social policy, economic regulation, and every other concern at once, then each national election is inevitably made to appear a contest upon which the whole political condition of the Republic depends. Federalism, properly understood, diminishes rather than enlarges these occasions for national conflict by leaving those questions which do not require a common national rule to the constitutional authority of the States. No faction need be made the national victor, nor another the national loser, in every political disagreement. The preservation of the Union does not require the nationalization of every political question; indeed, such nationalization may itself become an instrument of disunion.

Yet the same constitutional arrangement which protects the States from unnecessary national interference imposes upon them an equal obligation to respect those powers which the Constitution has lawfully entrusted to the Federal Government. When Congress acts within that authority, disagreement by a State cannot transform valid federal law into an optional recommendation. A State remains free to challenge such a law before the courts, petition Congress for its repeal, elect representatives committed to its alteration, or seek constitutional amendment where necessary; but it cannot preserve the Union while simultaneously claiming a power to nullify those national laws it finds disagreeable. Neither does federal supremacy permit the National Government to command the States to administer every federal policy on its behalf. A State may, within constitutional limits, decline to employ its own officers or resources in the execution of a federal program; what it may not do is obstruct the lawful exercise of federal authority itself. The distinction between refusing cooperation and attempting nullification is essential to the preservation of genuine Federalism. Nor can popular approval alone settle the question of constitutional authority. If the people desire a national policy which exceeds the powers presently entrusted to the Federal Government, the proper remedy is not to disregard the Constitution but to pursue that policy through the States where appropriate or, if national authority is truly required, to amend the Constitution. If, however, that policy rests upon legitimate federal authority and has been enacted through the constitutional process, the States remain bound to respect it regardless of temporary political disagreement. The Constitution grants neither Washington a general authority over the States nor the States a veto over the lawful authority of the Union.

The danger to the Union begins when either government ceases to regard these boundaries as obligations and instead treats them as inconveniences to be discarded whenever political advantage recommends it. From the National Government, this error takes the form of consolidation: the gradual assumption of powers properly reserved to the States until their constitutional authority becomes little more than a formality. From the States, it takes the opposite form of nullification: the claim that lawful national authority may be resisted or disregarded whenever its exercise offends the policy or political interests of a particular State. Though these errors proceed in opposite directions, their effect upon Federalism is much the same. The former preserves the Union by extinguishing the States; the latter preserves the States by extinguishing the authority which makes them members of a Union. Neither can be reconciled with the constitutional system we have inherited.

Nor is the spirit of disunion confined to controversies between governments. It may take root among the people themselves whenever constitutional institutions are regarded as legitimate only while they produce the results desired by a particular faction. Congress does not cease to possess its constitutional character because it enacts a law we oppose; the Executive does not become illegitimate merely because its lawful authority is exercised by a political adversary; nor does the Judiciary forfeit its place within the constitutional order whenever its judgments disappoint us. Their acts may be condemned, challenged, appealed, repealed, or restrained by the means the Constitution provides; but no Republic can endure if each faction recognizes the legitimacy of its institutions only while it remains victorious. The same principle must govern our understanding of political protest. A citizen remains free to denounce the Government, condemn the history of the Republic, display the national flag in distress, burn that flag, or raise the banner of another nation as an expression of political belief. Many Americans may regard such acts as offensive, unpatriotic, or even hostile to the spirit of national unity; yet the constitutional liberty to express such sentiments is itself among the liberties the Union exists to secure. The strength of a free Republic is demonstrated not by suppressing expressions of contempt toward it, but by preserving the liberty under which even such contempt may be expressed.

But the liberty to oppose lawful authority is not a liberty to prevent its lawful exercise by force. When protest passes into assault, physical obstruction, or deliberate interference with officers executing powers constitutionally entrusted to the Federal Government, the character of the act is altered. Political disagreement remains protected; private nullification does not. A citizen may demand the repeal of a federal law, challenge it in court, organize against it, or seek the defeat of those who enacted it. He may not substitute his own force for the constitutional processes by which that law is to be judged. Recent demonstrations against federal immigration enforcement in California illustrate this distinction. Those who opposed federal policy possessed every right to protest its enforcement and to express, however forcefully, their disagreement with the Government. Even rhetoric describing American territory as wrongfully acquired, or asserting that lands presently within the Union properly belong to another nation, remains within the broad liberty of political advocacy. The Federalist is nevertheless under no obligation to regard such ideas as harmless. When historical grievance is employed to deny the legitimacy of the present Union or to encourage Americans to regard portions of their own Republic as the rightful possession of a foreign state, the argument ceases to concern history alone and begins to touch directly upon national allegiance and the integrity of the Union.

Such an argument must be answered, not silenced. The First Amendment secures the liberty to advocate even propositions hostile to the existing constitutional order; it does not require the citizen to pretend that every proposition so protected is equally conducive to the preservation of that order. Nor does political allegiance to the United States demand the abandonment of ancestry, language, culture, or affection for the countries from which our families may have come. The Republic has always drawn citizens from many peoples. But the political allegiance of an American citizen cannot depend upon ancestral origin. Whatever the land of his fathers, his constitutional country is the United States; and whatever his political disagreements with its Government, his fellow citizens remain members of the same Republic.

Disunion therefore begins long before a State formally declares its separation from the Republic. It begins whenever constitutional allegiance becomes conditional: when the National Government treats the States as administrative conveniences; when a State obeys federal law only while agreeable; when a faction recognizes institutions only while victorious; when lawful authority is met not with constitutional opposition but with obstruction; or when Americans are encouraged to regard one another not as political opponents within a common Republic, but as members of hostile peoples possessing no common political country. A Perpetual Union requires no uniformity of opinion; it requires instead a common determination to remain one people while exercising the liberty to disagree. More dangerous still is the moment at which faction abandons the constitutional means of opposition altogether and substitutes force for persuasion, election, petition, and law. The citizen possesses every right to condemn his Government, demand the repeal of its laws, challenge their constitutionality, organize for their defeat, and advocate even fundamental alterations to the political order. These liberties belong not merely to those whose opinions strengthen the Union, but equally to those whose opinions we may consider hostile to it. Yet no liberty of political expression confers upon any private combination a right to oppose by force the lawful authority of the United States, to prevent the execution of constitutional law, or to substitute its own judgment for that of the constitutional Republic. Where political opposition assumes this character, it ceases to be merely dissent and approaches sedition against the lawful order itself.

A free Republic must therefore possess both the restraint to tolerate the most severe criticism of itself and the strength to resist those who would overthrow or obstruct its constitutional authority by force. To punish opinion as sedition would betray the liberty of the Union; to excuse genuine sedition as mere opinion would betray the Union which secures that liberty. These considerations establish the obligations which the Union imposes upon governments, factions, and citizens alike; but the permanence of that Union, and the consequences which have attended attempts to place sectional interest above national allegiance, demand a further examination.
