Rothbard’s book combines intellectual history, political argument, and memoir. Its governing argument is that American conservatism did not preserve the older Right but displaced it. The “betrayal” names the replacement of an anti-statist, antiwar, anti-New Deal movement by a Cold War conservatism committed to military mobilization, executive power, and anti-Communist empire.
The Old Right was staunchly opposed to Big Government and the New Deal at home and abroad: that is, to both facets of the welfare-warfare state.
The Right Rothbard recovers is therefore not primarily nationalist, traditionalist, or managerial. It descends from Jeffersonian suspicion of central power, Jacksonian hostility to privilege, abolitionist radicalism, Cobdenite peace politics, and the individualist criticism of Mencken, Nock, Flynn, Villard, and Chodorov. What later looked “conservative” was, in this genealogy, a radical liberal opposition to state power, monopoly privilege, bureaucracy, and war.
The difference between the two right wings, “Old” and “New,” and how one was transformed into the other, is the central theme of this book.
Rothbard traces that transformation through World War I, the New Deal, World War II, and the Cold War. War is the central mechanism because it concentrates authority, disciplines dissent, expands administration, and habituates citizens to command. His antiwar politics rest on a class analysis drawn from Nock and Oppenheimer: exploitation arises less from market exchange than from taxation, conscription, political privilege, and state-protected monopoly.
Crying, “War is the health of the State,” Bourne declared: “Country is a concept of peace, of balance, of living and letting live. But State is essentially a concept of power.”
The New Deal then reorganizes American ideological language. Individualists who had once belonged to liberal or radical circles are pushed to the Right because progressives, socialists, and Communists enter Roosevelt’s coalition. Rothbard insists that the libertarians had not changed; “liberalism” had. To the Old Right, the New Deal was not liberation but corporate statism, cartelization, and Hooverism intensified.
Foreign policy becomes the book’s deepest dividing line. Rothbard treats isolationism not as provincial withdrawal but as the authentic American anti-imperial tradition. World War II and the early Cold War nearly destroy that tradition by equating nonintervention with treason or fascist sympathy. Yet Flynn, Garrett, and others preserve its central warning: the greatest danger to American liberty is the domestic state that invokes foreign enemies to justify permanent power.
We have crossed the boundary that lies between Republic and Empire.
The memoiristic sections follow Rothbard through FEE, Mises’s seminar, Chodorov, Austrian economics, and his movement toward anarcho-capitalism. He first identifies with the most anti-interventionist Republican remnants—Taft, Buffett, Bender, Gross, and the Chicago Tribune—because they resist NATO, conscription, Korea, and Cold War militarization. But Buckley’s National Review becomes, in Rothbard’s account, the decisive instrument of betrayal: it preserves free-market rhetoric while subordinating liberty to anti-Communist state power.
Rothbard’s break with conservatism is therefore conceptual as well as tactical. With Leonard Liggio he rethinks the political spectrum, locating classical liberalism historically on the Left and throne-and-altar conservatism on the Right. New Left revisionists such as Williams and Kolko help him reinterpret Progressive regulation as corporate liberalism—intervention serving Big Business rather than restraining it. For a time, antiwar radicalism seems to revive the Old Right’s moral energy.
That alliance fails when the New Left turns toward Leninism, violence, and countercultural anti-intellectualism, while libertarians remain too weak to absorb allies without being absorbed themselves. The later chapters turn to Nixon, whose presidency completes the Right’s incorporation into the post-New Deal order through inflation, regulation, welfare-state management, and imperial foreign policy.
The book emphasizes bipartisan convergence. Liberal and conservative establishments differ in idiom, but both accept welfare, war, inflation, bureaucracy, and state-corporate capitalism. Rothbard’s alternative is a renewed coalition against the welfare-warfare state, joining civil liberty, economic freedom, anti-imperialism, and opposition to corporate privilege. The Betrayal of the American Right thus reconstructs libertarianism as the radical heir of antiwar liberalism and Old Right republicanism, and warns that movements for liberty are betrayed when they make peace with empire.
