IB History: The Cold War — notes, maps and essay questions

Chapter 1: The World the War Left

The security dilemma — two rational fears. The USSR, invaded twice through Poland in thirty years at a cost of 27 million dead, defined security as controlling everything between Berlin and Moscow. The United States, twice dragged into world wars by European collapse, defined security as ensuring no single power dominated Eurasia. Each definition made the other side’s nightmare true: Soviet buffer-building looked like expansion. American engagement looked like encirclement. No villain is required for this mechanism to run. Which is precisely what makes it worth studying.

Ideology made compromise read as defeat. This was not only a great-power rivalry. Leninism taught that capitalist encirclement guaranteed eventual war. American liberalism taught that closed societies breed aggression (the lesson of the 1930s). Both creeds were universal. Each side believed history itself was on its side. So every local dispute, from Polish ministries to Iranian oil, carried the weight of a verdict on the future of mankind.

Poland: the test case that failed. Watch Poland on this map. The country Britain went to war for in 1939. At Yalta, Stalin conceded “free and unfettered elections”. What followed were arrests of Home Army leaders, a rigged referendum (1946) and a falsified election (1947). For Washington, Poland proved Soviet promises were worthless. For Moscow, Western protest over Poland proved the West meant to re-encircle Russia with hostile states. One country, two proofs.

A power vacuum with two occupants. Germany and Japan. The powers that had organized Eurasia’s two ends. Were rubble. Britain was bankrupt (it would devalue and retreat from Greece, India and Palestine within three years). France was humiliated. Only two states retained the means to shape the world, and nothing but each other stood between them. Bipolarity wasn’t chosen. It was the arithmetic of 1945.

Chapter 2: Containment

Europe was starving, and hunger votes. The brutal winter of 1946–47 froze canals, halved German rations and pushed French and Italian communist parties. Already a quarter of the vote. Toward power through the ballot box. Marshall’s planners argued that empty stomachs, not Soviet tanks, were the immediate threat. The Plan was containment aimed at despair. It worked: Western European output passed prewar levels by 1951, and the communist vote crested and receded.

Why Moscow refused the money. Marshall aid was offered to the USSR and its sphere. Sincerely or as a wedge, historians still argue. Stalin sent Molotov to Paris with ninety economists, then pulled him out: the Plan required open accounts and integration into a Western-run system, which for a command economy meant surrendering control of its buffer. Refusing was rational for the regime and ruinous for its subjects. Czechoslovakia had voted to attend, and was overruled by phone. The two Europes on this map begin as two answers to one memo.

Berlin: geography as leverage. The 1945 occupation plan left the Western sectors of Berlin deep inside the Soviet zone with no written guarantee of ground access. Only three agreed air corridors, each twenty miles wide (your three arrows). Stalin’s blockade was calibrated below the threshold of war: no shots, just closed gates. The airlift answered in kind. No convoy forced through, just physics and logistics. Both sides discovered the Cold War’s grammar: pressure everywhere short of the trigger.

The bomb behind the politeness. America’s atomic monopoly (until August 1949) shaped both sides’ caution. Stalin would not shoot down transports. Truman parked B-29s in England as a signal. The bombers were not actually atomic-configured, an early bluff in a long tradition. Neither side wanted the war both were preparing for. The entire crisis ran on nerve.

Who ended it? The four-way argument. Pressure (Reagan school): the buildup and SDI made the arms race unaffordable and emboldened reformers. Choice (Gorbachev school): nothing required a Soviet leader to renounce force. A Li Peng in Moscow shoots, and this atlas ends differently. Structure (economics school): a 1970s-technology command economy at 15–20% defense burden was doomed regardless. Leaders only chose the exit’s date and decency. People (1989 school): Solidarity, Leipzig, the Baltic chain. Legitimacy was withdrawn from below, and no Kremlin decision could have restored it. The honest synthesis: structure set the stage, pressure raised the rent, Gorbachev declined to burn the theater, and the audience walked out. Weight them yourself. The exam will not, but history teachers forever will.

What the new map inherits. Nuclear arsenals in four sudden states (Ukraine, Belarus, Kazakhstan disarm by treaty within years. A nonproliferation triumph with a long shadow). Yugoslavia already dissolving into Europe’s first wars since 1945. The hatching on this final map. NATO victorious and open-ended. Russia, shorn of empire and depression-struck, nursing the narrative that it was not defeated but dismantled. The post-Cold-War order’s crises. Expansion debates, frozen conflicts, the 2014 and 2022 wars over exactly the Belovezha borders. Are footnotes to this snapshot. The era ended. Its map kept legislating.

The ledger of the “long peace”. No direct great-power war in 46 years. Deterrence, bipolar discipline, or luck (Ch. 6 says: all three). But the chart below counts what “cold” cost where the war was hot: Korea, Vietnam, Afghanistan, Angola, Cambodia, Ethiopia, Central America. Something like 20 million people died in Cold War-connected conflicts, almost none of them in Europe, most of them in the countries this atlas’s Chapter 8 insists were players and not squares. Both facts. The peace and the price. Are true. Keeping them in one sentence is the era’s epitaph.
