A Rivalry Under Threat
After World War II, the United States and Soviet Union emerged as superpowers. Their nuclear arsenals created the danger of mutually assured destruction: a direct war could destroy both sides.
Fighting Indirectly
Instead of open conflict, the rivals backed competing allies and movements. The United States fought communist forces in Korea and Vietnam, supported containment through the Truman Doctrine and Marshall Plan, and joined NATO. The Soviet Union responded with the Warsaw Pact.
Competition Beyond Battlefields
The Cold War unfolded through arms races, propaganda, intelligence operations, and technology. When Sputnik became the first artificial satellite in 1957, the shock intensified the Space Race and led to the creation of NASA.
The rivalry also shaped domestic life. McCarthyism targeted alleged communists in government and entertainment, while the fear of ideological subversion reached into civil society.
The Cold War ended with the Soviet Union’s collapse in 1991. Its paradox was lasting: the absence of direct superpower war did not mean peace, but a worldwide contest conducted everywhere except the central battlefield.
