“In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist.”—President Dwight D. Eisenhower, Farewell Address, January 17, 1961¹
Introduction: The War That Never Ended
On August 15, 1945, Americans celebrated V-J Day—the end of the most destructive war in human history. Sixteen million Americans had served; over 400,000 had died. The Japanese surrender meant the boys were coming home. The nation expected what had followed every previous American war: demobilization, return to normalcy, swords beaten back into plowshares.
After the Civil War, the Union Army had shrunk from over one million soldiers to roughly 27,000 within two years.² After World War I, the American Expeditionary Force demobilized almost entirely; by 1920, the Army had returned to its traditional peacetime strength of approximately 130,000.³ This was the American pattern: mobilize for war, then return to republican normalcy.
After World War II, something unprecedented happened.
The war ended, but the war footing did not. The bases remained. The military budget stayed high. New agencies were created not for wartime emergency but for permanent conflict. The temporary became permanent. The exceptional became normal.
The United States had won the war—and lost the republic the founders had designed.
This article examines how the national security state was constructed in the years following World War II. The institutions created in this period—the Department of Defense, the Central Intelligence Agency, the National Security Council, NATO, the global network of military bases—remain the architecture of American power today. Understanding how they were built, and what they replaced, is essential to evaluating whether the transformation was necessary, whether it has made Americans safer or more at risk, and whether it can ever be reversed.
The Old Right had warned that intervention would transform America into a garrison state. They predicted that emergency powers would become permanent, that constitutional limits would be abandoned, that the distinction between war and peace would dissolve.
Every one of their predictions came true.
The War’s Conduct: Total War, Total Victory
The Unconditional Surrender Doctrine
At the Casablanca Conference in January 1943, President Franklin Roosevelt announced that the Allies would accept nothing less than the unconditional surrender of Germany, Italy, and Japan. There would be no negotiated peace, no compromise, no armistice short of total victory.⁴
The doctrine had profound consequences.
Winston Churchill privately opposed it. He understood that unconditional surrender removed any incentive for moderate elements in enemy countries to seek a negotiated end to the war. If surrender meant national annihilation rather than merely military defeat, why would anyone surrender?⁵
Joseph Stalin welcomed the doctrine. It ensured that the Western powers would fight to the bitter end, exhausting themselves while the Soviet Union positioned itself to dominate postwar Europe.⁶
The unconditional surrender demand prolonged the war on both fronts. In Germany, it strengthened Hitler’s hand against internal opposition. The July 20, 1944 assassination attempt failed partly because potential supporters knew that even a successful coup would not produce acceptable peace terms—Germany would still face unconditional surrender.⁷ The war continued until Berlin fell and Hitler was dead.
In Japan, the doctrine complicated the path to peace. By mid-1945, Japan was clearly defeated. Its navy was destroyed, its cities burned, its empire collapsing. Elements within the Japanese government sought to negotiate surrender—but unconditional surrender meant potentially removing the Emperor, an outcome the Japanese military would fight to prevent.⁸
The atomic bombs were partly a consequence of this logic. How else could unconditional surrender be extracted from an enemy prepared to fight to the death?
The Moral Compromises
Victory in World War II required moral compromises that should not be forgotten.
Alliance with Stalin meant alliance with the greatest mass murderer in history to that point. The Soviet regime had killed millions through deliberate famine, purges, and the Gulag. American propaganda rehabilitated “Uncle Joe” for wartime consumption, but the reality of the alliance was that America fought alongside one totalitarian horror to defeat another.⁹
Strategic bombing of civilian populations was official Allied policy. The distinction between military and civilian targets—a cornerstone of just war theory—was deliberately abandoned. The firebombing of Dresden in February 1945 killed an estimated 25,000 civilians in a city of questionable military value.¹⁰ The firebombing of Tokyo on March 9-10, 1945, killed approximately 100,000 people in a single night—more than the immediate deaths at Hiroshima.¹¹
This was not collateral damage. It was deliberate policy to break enemy morale by burning cities and killing civilians. General Curtis LeMay, who directed the firebombing campaign, later acknowledged: “I suppose if I had lost the war, I would have been tried as a war criminal.”¹²
The moral distinction between Allies and Axis, clear enough when comparing democratic governance to totalitarian rule, blurred considerably when comparing methods of warfare.
The Atomic Age
Hiroshima, August 6, 1945: approximately 80,000 immediate deaths from a single weapon.¹³ Nagasaki, August 9, 1945: approximately 40,000 more.¹⁴ The radiation effects would kill tens of thousands more in the months and years that followed.
The decision to use atomic weapons remains controversial. Defenders argue it saved the lives that would have been lost in an invasion of the Japanese home islands—estimated at hundreds of thousands of American casualties and millions of Japanese. Critics argue Japan was already seeking peace, that demonstration on an uninhabited target might have sufficed, that the second bomb at Nagasaki was unnecessary, that the real purpose was to intimidate the Soviet Union.¹⁵
What is beyond dispute is that the atomic bomb changed everything. Warfare, strategy, diplomacy, the very meaning of national security—all were transformed by weapons capable of destroying entire cities in seconds. The world that emerged from August 1945 was qualitatively different from anything that had come before.
The permanent national security state that followed was constructed, in part, as a response to this new reality. If American cities could be annihilated without warning, permanent vigilance seemed necessary. If the enemy possessed such weapons, could America ever afford to disarm?
The Postwar Settlement
The Truman Succession
Franklin Roosevelt died on April 12, 1945, less than three months into his fourth term. Vice President Harry Truman, who had barely been briefed on major war decisions, suddenly found himself president at the most consequential moment in world history.
Truman learned of the atomic bomb project only after taking office.¹⁶ He had not participated in the wartime conferences that shaped the postwar world. He inherited decisions half-made, commitments partially given, and a group of advisors whose views would shape American foreign policy for a generation.
Those advisors—Secretary of State James Byrnes, General George Marshall, Undersecretary Dean Acheson, diplomat George Kennan—became the architects of the Cold War. They shared certain assumptions: that the Soviet Union posed an existential threat, that American power must be projected globally to contain that threat, that the prewar pattern of limited engagement was no longer possible.¹⁷
Truman’s personal style reinforced these tendencies. He prized decisiveness over deliberation. “The buck stops here” meant that he made decisions and moved forward—not that he reconsidered or second-guessed. The permanent national security state was built by men who believed in action, not restraint.
Yalta and Potsdam
The postwar settlement was largely determined at two conferences: Yalta in February 1945 and Potsdam in July 1945.
At Yalta, Roosevelt, Churchill, and Stalin divided the postwar world. The Soviet Union would dominate Eastern Europe—this was already a fact on the ground, as the Red Army occupied these territories. Germany would be divided into occupation zones. The United Nations would be created to manage international disputes. Stalin agreed to enter the war against Japan.¹⁸
Critics later condemned Yalta as a “sellout” of Eastern Europe. But Roosevelt had little leverage. The Red Army occupied the territory in question. Short of fighting the Soviet Union—unthinkable in February 1945—there was no way to prevent Soviet domination of Poland, Czechoslovakia, Hungary, and the rest.
At Potsdam, with Roosevelt dead and Churchill soon to be voted out of office, Truman represented an America that possessed the atomic bomb. Germany’s division was formalized. Japan was issued an ultimatum demanding unconditional surrender—with the implicit threat of atomic destruction.¹⁹
The Cold War framework was established before the hot war ended. The wartime alliance against Hitler gave way almost immediately to confrontation between the former allies.
The Soviet Question
Was the Cold War inevitable? Did Soviet expansionism make confrontation unavoidable, or did American actions provoke Soviet defensiveness?
Traditional historians emphasized Soviet aggression: Stalin’s violations of Yalta agreements, the installation of communist governments in Eastern Europe, the blockade of Berlin, support for communist movements worldwide.²⁰
Revisionist historians emphasized American provocation: the abrupt termination of Lend-Lease, the denial of reconstruction loans, the atomic monopoly wielded as diplomatic leverage, the encirclement of the Soviet Union with military bases.²¹
The honest answer is that both sides contributed. Soviet behavior was genuinely threatening—the consolidation of Eastern Europe, the support for communist insurgencies, the development of nuclear weapons. American behavior was genuinely provocative—the assumption that Soviet security concerns were illegitimate, the demand that Eastern Europe be “free” according to American definitions, the military buildup that encircled Soviet territory.
The Cold War was not inevitable. Choices were made on both sides. American choices were choices—not forced upon unwilling leaders by Soviet action, but selected from alternatives by policymakers who believed confrontation was preferable to accommodation.
The Truman Doctrine: Permanent Intervention
The British Withdrawal
In February 1947, the British government informed the United States that it could no longer maintain its commitments in Greece and Turkey. Britain, exhausted by war and facing economic crisis, was withdrawing from its traditional role as the dominant power in the Eastern Mediterranean.²²
This was a pivotal moment. For over a century, Britain had maintained the balance of power that kept the sea lanes open and prevented any single power from dominating Europe. Now Britain was passing the imperial torch—and the question was whether America would pick it up.
Greece was fighting a civil war between the royalist government and communist insurgents supported by Yugoslavia. Turkey faced Soviet pressure for territorial concessions and control of the Dardanelles. If America did not act, the thinking went, both countries might fall into the Soviet orbit.²³
The Speech
On March 12, 1947, President Truman addressed a joint session of Congress. His speech would become known as the Truman Doctrine, and it committed America to a role Washington and Jefferson would not have recognized.
Truman declared:
“I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures. I believe that we must assist free peoples to work out their own destinies in their own way.”²⁴
And further:
“The free peoples of the world look to us for support in maintaining their freedoms. If we falter in our leadership, we may endanger the peace of the world—and we shall surely endanger the welfare of our own nation.”²⁵
The Significance
The specific request—$400 million in aid to Greece and Turkey—was modest. The commitment was unlimited.
The Truman Doctrine contained no geographical boundaries. It applied wherever “free peoples” faced subjugation. It contained no temporal limits. It would continue as long as threats existed. It provided no clear definition of which peoples qualified as “free” or which pressures justified American intervention.
The language was designed to be open-ended. Dean Acheson later acknowledged that the administration deliberately framed the issue in ideological rather than strategic terms to mobilize congressional and public support.²⁶ The specific situation in Greece and Turkey became the occasion for a general commitment to global intervention against communism.
Senator Robert Taft voted for the Greek-Turkish aid but warned against the doctrine’s expansive language:
“I do not want war with Russia... If we assume a special position in Greece and Turkey, we can hardly... object to the Russians’ continuing their domination in Poland, Rumania, and elsewhere.”²⁷
Taft’s warning proved prophetic. The Truman Doctrine’s logic would justify Korea, Vietnam, and interventions on every continent. Once America committed to opposing communism everywhere, there was no limiting principle.
The National Security Act of 1947
The Legislation
On July 26, 1947, President Truman signed the National Security Act into law. This single piece of legislation created the institutional architecture of the permanent national security state.²⁸
The act unified the military services under a new Department of Defense, replacing the separate War and Navy Departments that had existed since the founding. It created the United States Air Force as an independent service. It established the Joint Chiefs of Staff as the permanent coordinating body for military planning.
Most significantly, it created two new institutions that had no precedent in American history: the Central Intelligence Agency and the National Security Council.
The Central Intelligence Agency
The CIA was ostensibly created to coordinate intelligence gathering and analysis—functions previously scattered among military intelligence services and the wartime Office of Strategic Services. America needed, the argument went, a permanent peacetime intelligence agency to monitor threats and inform policymakers.²⁹
The reality was more expansive. The CIA was given authority for covert operations—secret activities to influence foreign governments, support friendly factions, and undermine enemies. This authority was not explicit in the original legislation but was added through classified directives and expansive interpretation.³⁰
The agency operated with minimal oversight. Congressional committees were informed of its activities only selectively, if at all. The CIA’s budget was hidden within other appropriations. Its officers were immune from normal legal constraints when operating abroad.
This was something genuinely new. The United States had never maintained a permanent peacetime intelligence agency. The founders had been deeply suspicious of standing armies; they would have been horrified by a permanent secret service accountable to no one.
George Kennan, who helped design the containment strategy, later expressed regret:
“The greatest mistake I ever made was not recognizing early enough that the agency we created would become a Frankenstein’s monster.”³¹
The National Security Council
The National Security Act also created the National Security Council—a body designed to coordinate foreign policy, defense policy, and intelligence at the highest level. The NSC would advise the president on matters of national security, bringing together the secretaries of State and Defense, the military chiefs, and the intelligence director.³²
In theory, the NSC was an advisory body. In practice, it became the locus of real decision-making on war and peace. The NSC staff, operating from the White House, accumulated power that rivaled and eventually exceeded that of the State Department.
Congressional deliberation—the founders’ mechanism for preventing rash decisions on war—was marginalized. The NSC operated in secret. Its deliberations were classified. Its decisions were implemented before Congress knew they had been made.
The constitutional structure presumed that decisions about war and peace would be debated publicly by representatives accountable to voters. The national security state presumed that such decisions required secrecy, speed, and executive discretion.
What Was Created
The National Security Act of 1947 created:
A permanent military establishment unified under centralized command
A permanent intelligence apparatus operating outside normal legal constraints
A permanent advisory structure that concentrated war-and-peace decisions in the executive branch
The institutional framework for permanent mobilization
The Old Right’s nightmare had become law. The garrison state they warned against now had enabling legislation.
NATO: The Entangling Alliance
The North Atlantic Treaty
On April 4, 1949, the United States joined eleven other nations in signing the North Atlantic Treaty, creating NATO—the North Atlantic Treaty Organization.³³
Article 5 of the treaty declared that an armed attack against one member would be considered an attack against all:
“The Parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all and consequently they agree that... each of them... will assist the Party or Parties so attacked.”³⁴
This was precisely what Washington’s Farewell Address had warned against: a permanent entangling alliance that committed America to go to war automatically if any treaty partner was attacked.
The Senate Debate
The Senate debate over NATO ratification featured the last significant resistance to the emerging consensus.
Senator Taft opposed the treaty:
“The Atlantic Pact is a precursor to war... It is an alliance which obligates us to go to war if certain events occur. It obligates us to consider an attack on one member as an attack on all. It is a military alliance, and we are required to maintain an armed force sufficient to carry out those obligations.”³⁵
Taft warned that NATO would require permanent American military presence in Europe, enormous defense spending, and the subordination of American foreign policy to alliance obligations. The treaty contained no sunset clause, no mechanism for withdrawal, no limit on expansion.
He was outvoted 82-13.³⁶
The Long-Term Consequences
Every one of Taft’s predictions proved accurate.
American forces remained in Europe permanently. Bases established in 1949 remain operational today. Defense spending never returned to prewar levels.
The “temporary” alliance against Soviet threat continued after the Soviet Union dissolved in 1991. NATO not only survived but expanded—adding Poland, Hungary, and the Czech Republic in 1999; the Baltic states and others in 2004; and continuing to expand toward Russia’s borders in subsequent years.³⁷
The alliance originally designed to contain Soviet power became, after the Soviet collapse, an instrument for extending American influence ever eastward. Whether this expansion was wise, whether it contributed to the current confrontation with Russia over Ukraine, whether the alliance serves American interests or merely perpetuates institutional inertia—these questions remain contested.
What is beyond dispute is that NATO represents exactly what the founders warned against: a permanent military commitment to defend other nations’ territory, a standing alliance that limits American freedom of action, an obligation that operates automatically without fresh deliberation.
The Korean War: The Precedent
The War
On June 25, 1950, North Korean forces invaded South Korea. The invasion caught American policymakers by surprise, though it should not have—Secretary of State Acheson had publicly excluded Korea from the American defense perimeter just months earlier.³⁸
President Truman decided to intervene immediately. American forces, operating under United Nations authorization, were committed to defend South Korea and repel the invasion.
The war lasted three years. It killed approximately 37,000 Americans, along with hundreds of thousands of Koreans and Chinese.³⁹ It ended in stalemate, with the Korean peninsula divided along roughly the same line where it had been divided in 1945. North Korea remains a hostile, nuclear-armed dictatorship. American forces remain in South Korea today.
The Constitutional Violation
The Korean War established a precedent more damaging to constitutional government than any military outcome.
Article I, Section 8 of the Constitution grants Congress the power to declare war. This provision was not accidental or archaic—it was central to the founders’ design. They had seen how European monarchs dragged their nations into wars for dynastic or personal reasons. They wanted war to require deliberation, debate, and the explicit consent of the people’s representatives.⁴⁰
Truman never asked Congress to declare war on North Korea. He called the intervention a “police action” conducted under United Nations authority. When asked directly about a declaration of war, Truman responded: “We are not at war.”⁴¹
This was constitutionally untenable. A UN Security Council resolution cannot substitute for congressional declaration. The Constitution does not empower the president to commit forces to combat because an international body requests it. The commander-in-chief power is the power to direct forces in wars that Congress has declared, not the power to initiate wars on executive authority.
But the precedent was established. Truman fought a major war without congressional declaration—and succeeded politically. Every subsequent president has claimed similar authority. Korea, Vietnam, the Gulf War, Afghanistan, Iraq, Libya, Syria—none were fought under formal declarations of war.
The congressional war power, central to the constitutional design, became a dead letter.
MacArthur and the Limits
General Douglas MacArthur commanded UN forces in Korea. After initial setbacks, his brilliant Inchon landing turned the war around. American forces pushed north, approaching the Chinese border.
Then China intervened. Hundreds of thousands of Chinese troops poured across the Yalu River, driving American forces back in bitter winter fighting.⁴²
MacArthur wanted to expand the war. He advocated bombing Chinese bases in Manchuria, blockading the Chinese coast, and potentially using nuclear weapons. He publicly criticized administration policy, challenging civilian control of the military.⁴³
Truman fired him in April 1951. MacArthur returned home to a hero’s welcome and addressed Congress to thunderous applause. But his dismissal stood. Civilian control of the military—one constitutional principle that survived the transformation—was preserved.⁴⁴
The war ended in 1953 with an armistice, not a peace treaty. The model for future American wars was established: limited objectives, no victory, no declaration, no end.
NSC-68: The Blueprint
The Document
In April 1950—before the Korean War began—the National Security Council produced a document that would serve as the blueprint for permanent American militarization: NSC-68.⁴⁵
Authored primarily by Paul Nitze, the document framed the Cold War in apocalyptic terms. The Soviet Union posed an existential threat to civilization itself. Half-measures were inadequate. Only massive military buildup could preserve the free world.
NSC-68 called for tripling the defense budget. It advocated military buildup “whether or not there is a formal declaration of war.”⁴⁶ It proposed that the United States maintain sufficient force to fight simultaneously in Europe and Asia while deterring nuclear attack.
The Logic
The document’s logic was totalizing:
“A defeat of free institutions anywhere is a defeat everywhere.”⁴⁷
This single sentence captured the ideology of permanent intervention. If any country anywhere fell to communism, American security was diminished. There could be no peripheral interests, no areas outside the American perimeter, no limits to the commitment.
NSC-68 also embraced unlimited methods:
“The integrity of our system will not be jeopardized by any measures, covert or overt, violent or non-violent, which serve the purpose of frustrating the Kremlin design.”⁴⁸
Any measures. This language provided ideological justification for assassination, coups, propaganda, subversion—whatever was necessary. The end justified the means.
The Consequences
NSC-68 remained classified until 1975. The American public, whose taxes funded the buildup and whose sons fought the wars, was not permitted to read the document that justified these policies.⁴⁹
The Korean War provided the occasion to implement NSC-68’s recommendations. The defense budget did triple. The permanent military establishment that Garrett, Flynn, and Taft had warned against became reality.
The document’s framework—existential threat, global commitment, unlimited means—shaped American policy for the next four decades. It justified interventions on every continent, covert operations against dozens of governments, and military spending that consumed trillions of dollars.
The Military-Industrial Complex
Eisenhower’s Warning
On January 17, 1961, President Dwight D. Eisenhower delivered his farewell address. The speech is remembered for one phrase: the military-industrial complex.
“In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist.”⁵⁰
Eisenhower continued:
“We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.”⁵¹
The Irony
The irony was profound. Eisenhower had built the complex he now warned against.
His administration had expanded the nuclear arsenal from roughly 1,000 warheads to over 22,000.⁵² His administration had authorized CIA operations that overthrew governments in Iran and Guatemala. His administration had extended the network of global military bases. His “New Look” policy had relied on nuclear deterrence—the ultimate expression of permanent military readiness.⁵³
Eisenhower’s warning was sincere. He genuinely believed the military-industrial complex posed dangers to republican government. But it was a farewell address, not a governing philosophy. He warned against what he had enabled.
The Permanent War Economy
The military-industrial complex that Eisenhower described was not a conspiracy—it was an incentive structure.
Defense spending never returned to prewar levels. In 1940, defense spending was approximately 1.7% of GDP. After World War II, it settled at roughly 5-10% of GDP—a permanent peacetime militarization unprecedented in American history.⁵⁴
Defense industries became permanent constituencies. Companies that manufactured weapons depended on government contracts for survival. Their workers depended on those jobs. Their communities depended on those workers. Every congressional district had defense contractors, every state had military bases.
The incentive structure was perverse. Peace threatened livelihoods. War—or at least the permanent preparation for war—ensured prosperity. Reducing military spending meant unemployment, closed factories, abandoned bases. Increasing it meant jobs, contracts, campaign contributions.
This was not what the founders envisioned. They had deliberately kept the military small, relying on citizen militias rather than standing armies, precisely because permanent military establishments created constituencies for permanent war.
The military-industrial complex was the institutional expression of what Madison had warned against in 1795: war’s tendency to become self-perpetuating.
The Interventionist Defense
The Case for the National Security State
The interventionist position deserves fair statement.
The Soviet Union was a genuine threat. Stalin’s regime had murdered millions of its own citizens. Soviet forces occupied Eastern Europe. Communist parties, supported by Moscow, sought power across the globe. The Soviet development of nuclear weapons—achieved in 1949—meant that the American homeland could be annihilated.⁵⁵
In this environment, the argument goes, traditional American foreign policy was obsolete. The oceans no longer provided protection. Enemies possessed weapons of mass destruction. The luxury of non-intervention was no longer affordable.
The national security state, whatever its flaws, kept the peace. NATO deterred Soviet aggression in Europe. American nuclear forces prevented nuclear war. The global network of bases and alliances contained communist expansion. The Cold War ended with American victory and Soviet collapse—without the great-power war that would have killed tens of millions.
Perhaps the costs were high. Perhaps constitutional niceties were sacrificed. But the alternative—Soviet domination, nuclear war, the end of Western civilization—was worse.
The Response
This defense deserves serious engagement.
First, the Soviet threat was genuine but often exaggerated. Soviet capabilities were consistently overestimated by American intelligence. The “missile gap” that helped elect John F. Kennedy did not exist. The domino theory that justified Vietnam proved false. The monolithic communist bloc was actually riven by divisions—the Sino-Soviet split made nonsense of the idea that all communists everywhere served Moscow.⁵⁶
Second, containment was one policy response to Soviet power; the permanent national security state was another. One could advocate firm resistance to Soviet expansion without creating a permanent intelligence apparatus that overthrew governments, without abandoning congressional war powers, without military spending that consumed half the federal budget.
Third, the costs were real and predicted. The Old Right’s warnings about what permanent militarization would mean for American liberty have been vindicated. The surveillance state documented in The New Leviathan series, the erosion of civil liberties after September 11, the permanent war footing that continues decades after the Soviet collapse—these are the consequences of choices made in 1947.
Fourth, the Soviet Union collapsed despite American policy, not because of it. The Soviet system was economically unviable, politically illegitimate, and ideologically exhausted. Whether containment hastened its collapse, prolonged it through external pressure that justified internal repression, or had little effect either way is genuinely debatable.
Finally, the national security state did not dissolve when its justification disappeared. The Soviet Union collapsed in 1991. NATO not only survived but expanded. The CIA not only continued but grew. Military spending declined briefly in the 1990s before September 11 restored it to Cold War levels. The institutions created for a specific threat found new threats to justify their continuation.
Conclusion: The Republic Transformed
What Was Lost
The national security state replaced constitutional government with something different.
Congressional war power—the founders’ central mechanism for preventing executive adventurism—was abandoned without constitutional amendment. Presidents now take the nation to war on their own authority, citing UN resolutions, NATO obligations, authorizations for use of military force, or simply executive discretion. The last formal declaration of war was in 1942.⁵⁷
Civilian control over intelligence was never established. The CIA operated for decades with minimal oversight. When abuses were finally revealed in the 1970s—assassination plots, domestic spying, drug experiments on unwitting subjects—reforms were enacted, then gradually eroded.⁵⁸
Constitutional limits on executive action were replaced by the doctrine of “national security.” This phrase, appearing nowhere in the Constitution, became justification for secrecy, surveillance, detention without trial, and actions that would be criminal if performed by private citizens.
The founders’ foreign policy—peace, commerce, and honest friendship with all nations, entangling alliances with none—was replaced by permanent intervention, global military presence, and alliance obligations that commit America to fight for dozens of other nations.
The distinction between war and peace, fundamental to constitutional government, was abolished. The Cold War was neither formally war nor genuinely peace. The “War on Terror” continues indefinitely against an enemy that cannot surrender. The permanent emergency has become the permanent condition.
What Was Gained
Fairness requires acknowledging what the national security state achieved.
The Cold War ended without great-power conflict. Whatever role American policy played, the fact remains that the nuclear powers did not destroy each other.
Western Europe and Japan were protected. Countries devastated by World War II recovered under the American security umbrella to become prosperous democracies.
Soviet expansion was contained. Eastern Europe suffered under communist domination, but Western Europe did not.
American hegemony, for those who value it, was established and maintained. The United States emerged from the Cold War as the sole superpower, its military unchallenged, its economy dominant.
Whether these gains justified the costs—whether they could have been achieved at lower cost—whether they were American interests or merely the interests of those who managed American power—these questions remain contested.
The Question That Remains
The fundamental question is whether the transformation was necessary.
Could America have been secure without becoming an empire? The oceans still exist. Nuclear deterrence requires far less than the global military presence America maintains. Most of the interventions justified by Cold War logic—Vietnam, the coups in Iran and Guatemala, support for dictators across the globe—proved counterproductive or irrelevant to American security.
Has the national security state made Americans safer? The permanent war footing did not prevent September 11. The surveillance apparatus documented in The New Leviathan series has not obviously reduced terrorism. The interventions in Iraq, Libya, and Syria created chaos and strengthened the very forces they were supposed to defeat.
Can the transformation ever be reversed? The institutions created in 1947 have proven remarkably resilient. They survived the Soviet collapse that justified their creation. They have accumulated constituencies—defense contractors, intelligence agencies, military commands—with powerful interests in their perpetuation. Every attempt at reform has been captured or circumvented.
The Old Right asked whether America could remain a republic while becoming an empire. The national security state provides the answer: it could not. The institutions of empire are incompatible with republican government. Permanent military establishments, permanent intelligence agencies, permanent executive war-making—these are the apparatus of empire, not of republics.
Whether that transformation was worth it, whether it can be reversed, whether the republic the founders designed can ever be recovered—these are questions for citizens to answer, if citizens are still permitted to decide.
Self-Reflection Prompts
As you consider this history, ask yourself these questions:
Eisenhower’s Warning. Eisenhower warned against the military-industrial complex after spending eight years building it. What does this suggest about the difficulty of restraining institutions once established? Why might a president recognize dangers he felt unable to address while in office?
The Korean Precedent. Truman fought a major war without congressional declaration, calling it a “police action.” Do you believe this was constitutional? What are the long-term consequences of establishing the precedent that presidents can wage war without declarations?
NATO’s Persistence. NATO was formed to counter Soviet threat. The Soviet Union collapsed in 1991, yet NATO not only survived but expanded to Russia’s borders. Should NATO have dissolved after achieving its purpose, or does the alliance serve interests that justify continuation? What are those interests?
NSC-68’s Logic. NSC-68 stated that “a defeat of free institutions anywhere is a defeat everywhere.” Is this true? If America’s security depends on the success of freedom everywhere, are there any limits to American responsibility? What are the implications of accepting—or rejecting—this premise?
The Tradeoff. The national security state may have helped win the Cold War, but it transformed American government in ways the founders would not recognize. In your judgment, was the tradeoff worth it? What would have to be true for you to change your assessment?
