Cold War

Story hook

5 March 1946. Westminster College, Fulton, Missouri, population 8,000. A former British Prime Minister, voted out of office the previous July, accepted an honorary degree at a small liberal-arts college because the college's president had personally invited the sitting US President to attend. Harry Truman was there in the front row. Winston Churchill, 71 years old, in academic robes, delivered a speech titled "The Sinews of Peace". Halfway through, he uttered the metaphor that would name an era:

"From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent. Behind that line lie all the capitals of the ancient states of Central and Eastern Europe. Warsaw, Berlin, Prague, Vienna, Budapest, Belgrade, Bucharest and Sofia, all these famous cities and the populations around them lie in what I must call the Soviet sphere…"

The Iron Curtain had been a phrase used by Joseph Goebbels in 1945 and a few earlier writers — but Churchill turned it into a global proper noun. Joseph Stalin read the speech in Pravda and gave an interview calling Churchill a "warmonger" comparable to Hitler. The wartime alliance was over. Within fifteen months, Truman would announce his Doctrine of containment (12 March 1947), Marshall would announce his Plan (5 June 1947), and the Berlin Blockade (June 1948) would crystallise the geographic and political division of Europe. By 1949 the world had NATO (4 April 1949), Soviet nuclear weapons (29 August 1949), and a communist China (1 October 1949). The Cold War — a 46-year nuclear-armed standoff between the United States and the Soviet Union — had begun. It would end only on 26 December 1991, the day the Soviet flag came down over the Kremlin.

Why this matters for UPSC

UPSC's GS-I treats the Cold War as the organising structure of the second half of the 20th century. Prelims has tested NATO (1949), Warsaw Pact (1955), Cuban Missile Crisis (1962), Truman Doctrine, Marshall Plan, Brezhnev Doctrine, and dates of major proxy wars (Korea, Vietnam, Afghanistan). Mains framings ask about India's non-alignment, the role of nuclear deterrence, and decolonisation as Cold War battleground. Weight: medium for Prelims (heavy on dates), high for Mains (analytical frameworks). Specific proxy wars — Korea, Vietnam, Cuba — are covered in separate units; this unit treats the Cold War architecture.
