While the United States enjoyed unprecedented domestic prosperity and the expansion of the middle class during the postwar “Great Leveling,” its foreign policy was entirely consumed by the existential dread of the Cold War. The conflict with the Soviet Union was framed by leaders not merely as a traditional geopolitical rivalry, but as a totalizing clash between “alternate ways of life”—a zero-sum battle between free-market democracy and godless, totalitarian communism. To wage this global struggle, the United States fundamentally restructured its government, forging a formidable “national security state” that permanently altered the American republic.
The architecture for this new state was established by the National Security Act of 1947, which created both the National Security Council (NSC) to advise the president and the Central Intelligence Agency (CIA) to conduct foreign intelligence. Driven by the imperatives of a permanent war footing—codified in 1950 by the sweeping NSC-68 policy paper that demanded massive rearmament to contain Soviet expansion—the executive branch accumulated vast new legal, administrative, and war-making capacities. This concentration of authority birthed the “imperial presidency”. Under the banner of national emergency, presidents increasingly bypassed constitutional checks and balances; President Harry Truman, for example, committed U.S. troops to the Korean War without a congressional declaration of war, effectively conflating his authority as commander-in-chief with the unilateral right to initiate conflict.
To sustain this aggressive global posture, the United States developed an immense military-industrial complex. Defense budgets skyrocketed from roughly $12 billion before the Korean War to $40 billion by 1955, eventually reaching $80 billion by 1970. Charles E. Wilson, the president of General Electric, openly celebrated this “permanent war economy”. A handful of giant corporations received the vast majority of lucrative military contracts, forging a tight, interdependent alliance among the Pentagon, defense contractors, and academia. The sheer scale and unaccountability of this nexus became so alarming that President Dwight D. Eisenhower, the great hero of World War II, used his 1961 farewell address to explicitly warn the nation against the “unwarranted influence, whether sought or unsought, by the military-industrial complex,” recognizing its potential to endanger democratic processes.
Operating in the deepest shadows of this military-industrial expansion was the CIA, which rapidly morphed from an intelligence-gathering coordinating body into a highly lethal operational arm conducting covert warfare. Under the leadership of figures like Allen Dulles, the CIA operated essentially as a “secret government,” shielded from public accountability and congressional oversight. Dulles and his operatives believed that the Cold War was a ruthless struggle with no rules, concluding that “hitherto acceptable norms of human conduct do not apply”. The CIA became the “black-gloved fist” of the American power elite, empowered to subvert foreign governments and assassinate leaders who threatened American dominion.
Crucially, while the U.S. government justified its covert global interventions as necessary measures to stop the monolithic spread of Soviet communism, these operations were frequently deployed to protect American multinational corporate interests and suppress independent nationalism. The Cold War provided a potent ideological cover for economic imperialism.
Nowhere was this clearer than in the CIA’s interventions in the Middle East and Latin America. In 1953, the CIA orchestrated the overthrow of Iran’s democratically elected Prime Minister, Mohammad Mossadegh, after he nationalized the country’s oil industry. To protect Western oil interests, the U.S. installed the dictatorial Shah, whose brutal secret police ruthlessly suppressed political dissent for the next quarter-century. The following year, in 1954, the CIA launched a coup in Guatemala against the democratically elected, left-of-center President Jacobo Arbenz. Arbenz’s primary offense was not aligning with Moscow, but expropriating unused land owned by the United Fruit Company, a massive American conglomerate with deep ties to both Allen Dulles and Secretary of State John Foster Dulles. After CIA-backed mercenaries and American pilots bombed Guatemala City and forced Arbenz to flee, the new U.S.-installed dictator immediately returned the land to United Fruit, abolished taxes on foreign investors, and jailed thousands of political critics.
Ultimately, the Cold War’s legacy was profoundly paradoxical. In its zealous, heavily armed crusade to defend the “Free World” from totalitarianism, the United States built a sprawling national security apparatus that repeatedly thwarted democracy abroad and institutionalized secrecy, deceit, and unchecked executive power at home.
