Confrontation in Europe: containment, Berlin and the alliances

The big idea: By 1947 the wartime allies had become rivals. The United States decided it would no longer just watch communism spread — it would actively stop it.

This policy was called containment, and it had two arms: a political promise (the Truman Doctrine) and a huge cheque (the Marshall Plan).

The trigger was Greece. A civil war there pitted the government against communist fighters, and Britain — broke after the war — told Washington in early 1947 that it could no longer help.

Rather than let Greece and neighbouring Turkey fall, President Truman went to Congress in March 1947 and asked for money and a bold new commitment.

The Truman Doctrine (1947): Truman promised that the USA would support free peoples resisting takeover — and he framed the whole world as a choice between two ways of life: free versus totalitarian.

In practice this meant $400 million in aid to Greece and Turkey. In principle it meant the USA would now fight communism anywhere it threatened to spread.

Money alone would not save Europe, though. In 1947 much of Western Europe was still in ruins — cities bombed flat, factories idle, people hungry.

American leaders feared that poverty and despair were exactly what communist parties fed on, especially in France and Italy where they were strong.

The Marshall Plan (1947–48): Named after Secretary of State George Marshall, this was the European Recovery Program: around $13 billion of US aid to rebuild Western Europe's economies.

The logic was simple — a prosperous Europe would resist communism, and a rebuilt Europe would also buy American goods. Sixteen nations joined.

Two arms, one goal: Truman Doctrine = the words and the will. Marshall Plan = the money. Together they made containment real — and to Stalin they looked like America buying influence right up to the Soviet border.

Stalin saw containment as an attack. To him the Marshall Plan was 'dollar imperialism' — a way to pull Eastern Europe out of the Soviet orbit with cash.

He forbade the countries he controlled from joining, and hit back with two organisations of his own.

The sharpest clash came over Germany. After the war it was split into four zones (US, British, French and Soviet), and its capital Berlin — deep inside the Soviet zone — was itself split four ways.

The West and the Soviets could not agree on Germany's future, and by 1948 they stopped trying.

What set off the crisis: The Western powers merged their zones economically into Bizonia and, in June 1948, launched a new strong currency, the Deutschmark.

Stalin saw a rebuilt, capitalist West Germany forming on his doorstep — and West Berlin as a Western island he could squeeze.

The Berlin Blockade (Jun 1948 – May 1949): Stalin cut off all road, rail and canal routes into West Berlin, hoping to starve the Western powers out and force them to abandon the city — or give up their currency reform.

Over two million West Berliners were suddenly cut off from food and coal.

The Berlin Airlift: Instead of retreating or fighting their way in, the Western powers supplied West Berlin entirely by air. For nearly a year, planes landed roughly every few minutes, flying in food, fuel and medicine.

Stalin faced a choice: shoot down aircraft and risk war, or back down. In May 1949 he lifted the blockade. The West had won a huge propaganda victory.

The Berlin crisis convinced the West it needed a permanent military shield, not just economic aid. Poverty could be fixed with dollars, but tanks needed an army.

So in April 1949 — even before the blockade ended — twelve Western nations signed a defensive alliance.

NATO (1949): The North Atlantic Treaty Organization bound the USA, Canada and Western European states together in a promise: an attack on one is an attack on all.

For the first time in peacetime, the United States was formally committed to defending Europe. Containment now had military muscle.

Two German states (1949): Germany's division became official. In 1949 the Western zones became the Federal Republic of Germany (FRG / West Germany), and the Soviet zone became the German Democratic Republic (GDR / East Germany).

One country was now two, each tied to a rival superpower — the clearest symbol of a divided Europe.

The Soviet military reply came later. For a while Stalin had no matching alliance, but a key change forced his hand: in 1955 West Germany was allowed to rearm and join NATO.

An armed West Germany inside a hostile alliance was Moscow's nightmare, so the Soviets built a bloc of their own.

The Warsaw Pact (1955): The Warsaw Pact was a military alliance of the Soviet Union and its Eastern European satellite states, created directly in response to West Germany joining NATO.

Europe was now locked into two armed camps, facing each other across a divided Germany — the shape it would keep for forty years.

The pattern examiners want you to see: Every Western move produced a Soviet counter-move: Marshall Plan → Comecon, NATO → Warsaw Pact.

Use this action–reaction pattern to argue about who was responsible for dividing Europe — the heart of most Paper 2 questions on this topic.
