Containing Communism During the Cold War

After the War

In February 1945, the Nazis were on the run. The combined armies of Great Britain and the United States had liberated France and the Netherlands while the Soviet Red Army was steadily pushing in from the east. Hitler’s days were numbered. As World War Two drew to an end, British Prime Minister Winston Churchill, President Franklin Roosevelt and Soviet leader Joseph Stalin-- the leaders of the three great Allied nations, sat down at the Russian town of Yalta to work out the details for a post-war Europe. During the Yalta Conference, the ‘Big Three’ agreed to demand an unconditional surrender from Germany and to divide the conquered nation into four zones of occupation. After Germany surrendered in May, the Allies met again at Potsdam in July 1945 to hammer out the final details of occupation and de-nazification.

Stalin also agreed that fair and democratic elections would be held in areas occupied by the Red Army. But as soon as the war was over it became obvious that Stalin’s promise to his allies of free and fair elections turned out to be as worthless as a lifejacket made of bacon.

Joseph Stalin was not the kind of man who left things to chance and instead used force, intimidation, and even murder to make certain that voters in Soviet-occupied territories chose communism. Backed by Soviet tanks, Stalin installed pro-Soviet puppet governments by literally liquidating the opposition. You know, the sort of “accidents” where rival politicians fell out of third-story windows. Non-communists were denounced as Nazi spies and collaborators that were shipped off to Russian labor camps or shot on the spot. With Poland, Hungary, Romania, Bulgaria, and East Germany under Soviet occupation, Europe was transformed into a divided continent.

From Stalin’s perspective, this was about survival. Germany had invaded Russia twice in thirty years, killing tens of millions of Soviet citizens and devastating the country. Stalin wanted a buffer zone of friendly governments between the Soviet Union and Western Europe to make sure it never happened again. Whether that justified crushing democracy and murdering thousands of political opponents is another question entirely.

The Iron Curtain Drops

In March of 1946 Winston Churchill paid a visit to the United States where he gave a speech warning against the rising threat of Communist aggression. Churchill described the situation in Eastern Europe using the metaphor of an iron curtain to drive home the point that Europe was divided between the free and democratic nations of western and the communist police-states of Eastern Europe. Even more frightening, he spoke of secret “communist fifth columns” operating in Western and Southern Europe whose goal was to bring the entire continent under the red banner. Churchill warned that only a strong military stance could stop Soviet expansion and that the United States was the only country strong enough to take up the challenge.

The Truman Doctrine

In 1947, Greece was tearing itself apart in a civil war between communist rebels backed by the Soviet Union and the Greek government. Meanwhile, neighboring Turkey was under intense Soviet pressure to give up control of key straits connecting the Black Sea to the Mediterranean. Britain, which had been supporting both countries, was broke and could no longer afford to help. If Greece and Turkey fell to communism, the whole Mediterranean region could follow. The warhawks in Congress were calling for military action to drive the Soviets out of Poland and 97 Russian cities were drawn up as potential targets for nuclear bombing.

But President Truman took a more level-headed approach, instead he asked Congress for $400 million in emergency aid for Greece and Turkey. The Truman Doctrine laid out a plan to contain the spread of communism by providing money and resources to any country under threat of a communist takeover. The only other alternatives were either to do nothing and allow communism to expand worldwide or to start a war that probably couldn’t have been won. The Truman Doctrine became the basis for how the U.S. would fight the Cold War leading to U.S. intervention in Korea and Vietnam a few years later.

Europe in Chaos

In 1947, the Americans were the only ones with the atomic bomb, but Stalin had a weapon every bit as deadly: human misery. After the war Europe was a shriveled corpse of what it had been in 1939. Its great cities had been bombed into dust, factories, bridges, and railroads had been demolished, and miles of weed choked fields stretched across the continent. The death toll reached into the tens of millions but it was the living that were the real problem. Sixty million people were homeless refugees where only starvation and unemployment awaited them once they returned home. The postwar economy had sunk back into a depression and millions were on the verge of starving to death. Amid the chaos, membership in the communist party was growing throughout Europe. In France and Italy communists, instigated by Moscow, were staging massive strikes. Many feared that if something wasn’t done to stabilize Europe then the whole continent could fall to communism.

The Polish capital of Warsaw, like most major Europeans cities, was in complete ruins after the war.

The Marshall Plan

Secretary of State George Marshall came up with a plan that called for pumping an additional $13 billion in US aid to get Europe’s economy moving again. By this point, the United States had already given billions of dollars in aid to help ease the suffering but Europe’s economy remained hopelessly stalled. One of the biggest reasons was Germany. Before the war, Germany had been the largest producer and consumer on the continent. No one objected to helping America’s allies but many Americans objected to sending aid to a defeated enemy.

Predictably, the Russians fiercely objected to the idea of giving money to rebuild a country that had twice declared war on it. In fact, the Russians had in mind the exact opposite plan for the defeated Germans. Stalin had already begun dismantling German factories and shipping them, along with thousands of slave laborers, back to Russia. But Marshall argued that like it or not, European recovery could not happen without a strong Germany.

Convincing Congress to hand over that kind of money seemed like another impossible task. Conservatives claimed that we were giving away free money to Europe, liberals were afraid that the Marshall Plan would only antagonize the Soviets. And then, the Czech Foreign Minister Jan Masaryk mysteriously “fell” out of a window, followed by a communist overthrow of the Czech government. Congress saw the writing on the wall and approved the funds.

The Marshall Plan worked like a charm. The whole thing would be paid for with American money but the Europeans themselves would have to come together and cooperate on how the money was to be spent. The plan also called for an end to trade barriers to stimulate free trade and end the competition which had led to so many European wars in the past.

The Marshall Plan succeeded in putting Europe back on the road to recovery. In fact, it worked so well that by 1951 output was 35% higher than it had been in 1939. The years of the Marshall Plan overlapped the most rapid economic growth in the history of Europe. But the icing on the cake was with rising employment and food production the communist backbone in Italy and France had been broken. After all, what did Soviet communism have to offer a prosperous people?

NATO: An Alliance for Defense

Economic aid was one thing, but Western Europe remained militarily vulnerable. In April 1949, the United States, Canada, and ten European nations signed the North Atlantic Treaty creating NATO— the North Atlantic Treaty Organization. For the first time in American history, the United States committed itself to a permanent peacetime military alliance. The heart of NATO was Article 5, which stated that an attack on one member nation would be considered an attack on all. If the Soviets invaded France, they’d be at war with the United States. The message to Stalin was crystal clear: Western Europe was off limits.

NATO transformed the balance of power in Europe and became the cornerstone of Western defense throughout the Cold War. The Soviets answered in 1955 by forming the Warsaw Pact, their own military alliance that included the Soviet Union and seven Eastern European countries: Poland, East Germany, Czechoslovakia, Hungary, Romania, Bulgaria, and Albania.

On paper, the Warsaw Pact looked like NATO’s communist twin — a defensive alliance where an attack on one meant an attack on all. In reality, it gave the Soviets legal cover to station troops throughout Eastern Europe and maintain their grip on the region. Unlike NATO, where countries joined voluntarily, there was no option to leave the Warsaw Pact. When Hungary tried to withdraw in 1956, Soviet tanks rolled into Budapest. When Czechoslovakia attempted reforms in 1968, Warsaw Pact forces invaded to crush the movement. The message was clear: membership was permanent, whether you liked it or not.

The Berlin Crisis

At the Yalta Conference, it was agreed that Germany would be temporarily divided into four occupation zones until it could be de-nazified and it’s economy stabilized. The French, British, and Americans each controlled zones in the western half of the country while the Soviets controlled the east. The city of Berlin, deep within the Soviet Zone, had been divided in the same way. At some point in the future, the four zones would be merged into a unified Germany... or at least that was the plan.

As the Cold War began to harden it became obvious that Germany would not be reunited as one country. The Americans wanted to rebuild a strong and peaceful Germany. The Soviets on the other hand wanted revenge.

What they had in mind was to split Germany and reduce it to an agricultural country that could never again wage war on its neighbors. For a while the other Allies had been on board with restricting German industry. However, after the Marshall Plan, the Americans had a change of heart and they ceased sending German factories and machines to the Soviets.

After the Marshall Plan, cooperation between the United States and Soviet Union fell apart faster than a dollar store water gun. President Truman decided that it was time to stop “babying the Soviets” and went ahead with plans for unifying Germany without the cooperation of the Soviet Union. In 1948, the French, British, and Americans introduced a new German currency, the deutschmark, and announced the merger their three sectors into what soon would become West Germany.

The Berlin Air Lift

Stalin immediately retaliated by announcing the complete blockade of Berlin, severing all land travel between West Germany and West Berlin. For months open access between the zones had been allowed and Germans freely moved between east and west without any problems. But all that came to an abrupt halt when a directive came from Moscow declaring that “free and unrestricted use of the established corridor (between West Germany and Berlin) would no longer be permitted…”

The Soviets were effectively holding Berlin hostage in an effort to force the Allies to surrender it. But instead, the plan backfired. The Americans weren’t going to lose face by giving up control of Berlin and instead decided to bypass the Soviet blockade by simply flying food, medicine, and clothing over Soviet controlled East Germany. For fifteen months more than 250,000 flights were made to save the people of West Berlin from starvation. The Soviets could have shot down the American planes but that would have certainly sparked a war and so they helplessly sat back and watched their scheme go up in smoke. In the end, the Soviets had no choice but to admit defeat and on September 30, 1949 abandoned the blockade.

Berlin Divided

The division between East and West Germany was complete. In 1949, Stalin responded by creating a new country, dubiously named the German Democratic Republic, AKA “East Germany”. East Berliners now found themselves living under a communist dictatorship. However, many East Germans continued to freely travel to the western half of the city where they made their escape to West Germany. That is until 1961 when the Soviets ordered the construction of the Berlin Wall which sealed East Germans behind a barrier of concrete, barbed wire, and machine gun nests. It remained standing until 1989 when East Germany collapsed and the wall was torn down. For the rest of the Cold War, the Berlin Wall remained the most powerful symbol of communist oppression. Over 100 people died trying to cross it, killed by their own government for the crime of wanting freedom.

The Berlin Wall was a 96 mile long concrete barrier that completely surrounded the eastern section of Berlin until it was demolished in 1989.

Why It Matters

The decade from 1945 to 1955 didn’t just divide Europe — it established the playbook for the entire Cold War. Containment became America’s go-to strategy for the next forty years, from Korea to Vietnam to Afghanistan. The Marshall Plan proved that throwing money at a problem could actually work if done right, and it became the model for foreign aid programs ever since. NATO showed that the U.S. was willing to commit military forces to defend allies, a promise that’s still in effect today with over 30 member nations. And that divided Berlin? It stayed split until 1989, a constant reminder of how a world war had turned into a cold one.

Here’s the thing: these Cold War patterns never really went away. NATO is still around and still matters — just ask Ukraine, which has been trying to join since Russia invaded in 2022. The tension between Russia and the West over Eastern Europe? That’s the same argument Stalin and Truman were having in 1947, just with different players. The United States still uses economic and military aid to support allies and contain rivals. The specific ideology might have changed (it’s not really about communism versus capitalism anymore), but the basic geopolitical chess game that started in the rubble of World War Two is still being played today. Understanding how it all began helps explain why the world looks the way it does right now.
