Standard Version


We often think of history as something that was supposed to happen. We think that because it did happen it could not have been stopped. For example, in this week how many of the things that happened were meant to happen, and how many were the result of choices that people made? Natural disasters, like earthquakes cannot be avoided, but decisions by governments and the latest social trends are the result of human choices.

When we study the Cold War, we should think about how much the choices made by people led to what happened next. The Cold War split the world in two and messed up people’s lives in a great way for over 40 years. When the Cold War began, could people have made better choices? If they could have, why didn’t they? Why didn’t they just stop the Cold War from starting?

But sometimes events get out of control, and there is nothing that people can do to stop them. If this was true with the Cold War, what were the things that got out of control? What were the things that caused the Cold War that were too powerful for people to stop?

These are the questions that we will ask as we start the study of the Cold War. As World War II was ending, it seemed like the whole world was turned up-side down. It was not the way it was before World War II, and people were trying to figure it all out. Could government leaders, military leaders and everyday people have made different choices than they did that could have kept the Cold War between the East and the West from starting? Or was the Cold War going to happen anyway?


The basic difference in the Cold War was between two ideas about how the world should work. It was not a war about religion, in the way that Hitler’s hatred of Jews led to the Holocaust. It was not a war about raw materials and power, like the Spanish-American War was. And it was not really about who had charge of what land, like the Indian Wars of the late 1800s were.

But it was a fight to decide which of the ideas of how the world should work would be chosen in different parts of the world. It was an attempt to control how people would live their lives in those different areas.

The Cold War was a long and often violent struggle to bring the people of the world into either a free market economic system, or communism. These two competing ideas were not new. The struggle between those who supported these two ideas of how the world should work had been going on for years and years.

In the United States we have a free market economic system. This is sometimes called capitalism. In a capitalist system, all of your choices are free, but everything costs money, or capital. For example, you are free to choose what to buy, where to buy it, and how much to spend. Of course, you have to pay for what you buy. Also, the store owner can choose what to make and sell, and how much to charge for what he or she sells. The owners can also decide who to hire to work for them, and how much they are willing to pay their workers. No one makes the workers take a job, and they can quit if they want to. It is their choice. We call capitalism a free market economy because everyone is free to make whatever choices he or she wants. Notice that in a free market economy the government is not involved in any way. (Dad speaking: Of course this is blatantly untrue, but I suppose that is a subject for a much more advanced class.)

Capitalism may be simple because it requires no one to plan it, but it is not perfect. Some people will come up with very smart ideas, or be especially clever, or their hard work may make a lot of money for them, and they may become very rich. And some people who are lazy, or just have back luck, will end up being poor. In a free market world, there are classes of people. The upper classes own businesses and have control over most of the money, and the middle and lower classes do the work for the upper class.

Communism is different in every way. In the 1800s, two German intellectuals, Karl Marx and Friedrich Engels, saw the suffering of millions of people who worked every day in factories owned by a few wealthy men who had so much money they couldn’t possibly spend it all. Marx and Engels were sure they knew a better, more fair way to make the world work. In 1848, they wrote their ideas down into a short book and published it with the name, “The Communist Manifesto.”

Marx and Engels thought that the money of the world should be shared by the workers who made that wealth possible. Farmers should share the money earned for the food they grew. Factory workers should get some of the money earned from the goods they made. Businesses would have no owners, only workers. Marx and Engels said that if their ideas were put into practice no one would be poor. Anyone who wanted a job and was willing to work could have a job. The things and the food that the people produced would be shared by all the people who worked. Marx, Engels, and those who thought as they did had a saying: “From everyone according to his ability, to everyone according to his need.” In other words, everyone would do their best at whatever they were best at for the good of the nation, and everyone would share the country’s wealth.

Propaganda, such as this poster from the Soviet Union, was common in the communist world. Advertising is a sign of a free market economy. So, instead, the Soviet government used propaganda to urge the people to work hard for the good of the country.

Communism sounded like a good idea, but in the real world people with money — the upper classes — used their money to try to get the people who ran the government to do what they wanted done. They did not want to see communist ideas carried out. Imagine how John D. Rockefeller or Andrew Carnegie must have felt about communism! Marx and Engels had followers in both Europe and the United States. The International Workers of the World, a union that wanted to start a communist revolution in America, tried to get the working classes to throw out the government. Of course, many people were against them. Often called the “Wobblies,” their top leader, Frank Little, was murdered in Butte, Montana when he went there to lead a strike of copper miners. In the United States people were so afraid of communism, that in the years after the First World War a Red Scare moved across the nation, and more laws against immigration were passed, in part to keep people from Europe who might like the idea of communism out of the US.

However, in Russia communism did not turn out so well. Millions of poor farmers hated the king, or Czar of Russia, Nicolas II, and the rest of his family. In 1917 Russia was losing to Germany in the First World War. With the men dying in the war, Russians were ready for a change. Vladimir Lenin grabbed the opportunity. His followers, called Bolsheviks, took power away from the Czar, and created the world’s first communist nation, changing their country’s name to the Union of Soviet Socialist Republics (USSR), or the Soviet Union for short.

Vladimir Lenin led the successful revolution in Russia in 1917 and established the Soviet Union as the world’s first communist nation.

When Lenin died in 1924, the person who was second in charge took power. The new Soviet leader was Josef Stalin, a cruel man who put into prison and killed many thousands of the people of the USSR. In many ways, Stalin was just as terrible as Hitler, but during World War II the United States was at war with Germany (the Nazis) and so was Stalin’s Soviet Union, which made the United States and the Soviets partners. Being on the same side, however, did not make the Soviets or the Americans think any better of each other’s ideas about communism or capitalism.

Americans had seen what communism was like in the real world. Lenin, Stalin and the Soviet leaders had taken away the property of the wealthy. They had forced millions of people to give up their land, and moved thousands of people to work on farms and in factories run by the government. They arrested or killed those who spoke out against the government. Communism was not the perfect system that Marx and Engels had promised a century before. Americans did not want to become a communist country. They also did not want anyone else in the world to have to live in a communism nation like the Soviet Union.


President Franklin D. Roosevelt was first elected in 1932 when the Great Depression was at its worst. His New Deal programs had made him so popular that Americans elected him a total of four times. Near the end of World War II Roosevelt was in his fourth term as President. One of the most important things he did was to go to meetings with leaders of other nations (the Allies) that were fighting to win against the Nazis. These meetings were meant to help the allies plan how to beat the Axis Powers (Germany and its partner nations). But in 1945 everyone could see that the Allies were winning the war, so the Allied leaders met to plan for the future. After all of the terrible damage done by the war, what kind of future world would they build?

The Yalta Conference, held in February of 1945, in the Livadia Palace near the Soviet town of Yalta, was one of these important meetings. President Roosevelt, Prime Minister Winston Churchill of the United Kingdom, and the Soviet Union’s Josef Stalin were there. Roosevelt wanted the Soviets to help America beat Japan in the Pacific, especially because America thought that Japan might invade the US. Roosevelt also wanted Stalin to agree to join a new United Nations. Churchill wanted fair elections and democratic governments in Eastern and Central Europe. But Stalin wanted to see communism lead the governments of those countries. He thought that this would keep other countries from attacking the Soviet Union in the future. The Yalta Conference ended with general agreement between the leaders, but since the war was not over, they would need to meet again.

There were different people at the next meeting of the Allied leaders. On March 29, 1945, President Roosevelt died from a stroke. People in the US and around the world were shocked and very sad. They had not known of his failing health. On May 8, less than a month after his death, the war in Europe ended. America’s new President, Harry S Truman said that Victory in Europe Day and its celebrations were in honor of Roosevelt. Truman said that his only wish was “that Franklin D. Roosevelt had lived to witness this day.” In the United Kingdom the people voted for Clement Attlee to be Prime Minister instead of Churchill.

When the Allied leaders met in the city of Potsdam, German in July of 1945, the war in Europe was already over. Germany had surrendered. Hitler was dead. Truman did not say so, but he was about to use the nuclear bomb to end the war with Japan. The choices the leaders made at the Potsdam Conference would change the map of Europe, especially for beaten Germany.

The leaders agreed that the Soviet Union would have control over Eastern Europe, including Poland, Czechoslovakia, Hungary, Romania, Albania, and Bulgaria. Germany would be split into four areas. The Soviet Union, the United Kingdom, the United States and France would each control one of the areas. Germany’s capital city, Berlin, was inside of the Soviet area, or zone, but it too would be split up into four zones. In the years that followed, the western allies joined their zones together to make West Germany and the city of West Berlin. The Soviet Union, however, set up communist governments in each of the nations they had beaten in the war and created East Germany and the city of East Berlin.


Like Europe, the rest of the world also saw major changes. Since the 1800s, large areas of Africa and Asia had been run as colonies by the great countries of Europe. During the twenty years after 1945, most of these colonies asked for, fought for, or were given independence in a process known as decolonization. India won its independence from the United Kingdom in 1947 under the great leader Mahatma Gandhi. In Africa, dozens of new countries were created. The same thing happened in the Middle East. It was there that Jews from Europe who lived through the Holocaust created the new nation of Israel along the eastern side of the Mediterranean Sea in the land talked about in the Bible.

Most of the old colonies were terribly poor. For years and years the people of Europe had taken their oil, minerals, diamonds, and rubber, and given almost nothing back to them. Europeans hadn’t spent their own money to make their colonies better. For example, in the Congo, a colony of 13 million people, only 16 people had a college degree when it won its independence from Belgium in 1965. Without educated people, many of these new countries had a very hard time setting up solid governments that could run all of their land and their rich natural resources.

Both the United States and the Soviet Union were interested in the future of this new, free Third World. The Soviets thought that they could spread communism there. Americans believed that these new countries could only be free if the spread of communism was stopped. Both superpowers (the US and the Soviet Union) also wanted to be able to get the natural resources of the Third World. This would help them in a big way in their race to have more powerful technology than the other superpower.

Countries were not excited about working together after World War I. Without the United States participating, the League of Nations was not strong enough to stop Germany and Japan from wanting to add to their territory. Maybe a stronger international body, like Woodrow Wilson had wanted, was needed to keep the large nations from tearing the world apart.

Even though the Soviet Union and the western allies had different ideas about how governments should run, the idea of countries around the world working together came out of World War II. Along with other things, this was because people realized that each country trying to go it alone had failed. So this new sprit of working together led to the birth of the United Nations (UN) in 1945, with its main office in New York City.

People chosen by countries from around the world met in San Francisco in 1945 to write the rules for a United Nations. Even though there were many different ideas and sometimes hard feelings between the people there, the rules for the new United Nations (UN) were agreed to by everyone.

The UN charter (the rules that were agreed to) set up a Security Council, which is the executive branch of the United Nations. The Security Council must say okay to any action that the UN takes, such as economic sanctions, the use of military might, or the use of soldiers to keep the peace in times of war.

The five countries that won World War II, the United States, Great Britain, France, China, and the Soviet Union (now Russia) each hold a seat on the Security Council that cannot be taken away. Ten more seats are held by other countries. They are chosen by the UN General Assembly every two years. The five permanent members hold the power of veto. No action can take place unless all five agree. As the Cold War became more firm, the veto power of the United States and the Soviet Union often kept the Security Council from taking strong action when difficult and important decisions needed to be made.

The main body of the United Nations is the General Assembly. Every member nation holds a seat in the General Assembly, which is often called a town meeting for the world. The General Assembly has smaller groups, or committees, to deal with regular problems of the world, such as money, social problems, different rules in different countries, the problems of people in need of help, and others. The General Assembly has the power to give advice to the Security Council, but has no power to make the Security Council do anything.

The United Nations has a Secretary General who is chosen by the Security Council. He or she runs the day-to-day activities of the UN. The United Nations charter does not say exactly what the Secretary General should do, but the people who have been Secretary General have used the job to try to bring peace to the world by helping countries find a solution to their differences, and to advance the cause of human rights. It is a custom that the Secretary General is never from one of the five permanent member countries. The Secretary Generals over the past sixty years have come from nations like Norway, Peru, South Korea, Thailand, Egypt, Ghana and Spain. The UN does other things too. It has an International Court of Justice, and it helps women and children, and people forced to leave their own country. It also works to end disease and the problem of not enough food in the world through programs such as UNICEF and the World Health Organization.

After his death, when the war was over, Franklin Roosevelt’s wife, wanted the United Nations to write an International Declaration of Human Rights. Even though it has been broken many times, the declaration that she helped to write is a noble goal for each country to try to follow.

The old League of Nations failed, but the UN has done many good things, including helping to keep the peace in areas where there is war, helping more people in the Third World learn to read, and giving the okay for countries to send their army to fight off countries that are threatening other nations.

In 1945, and today as well, the United Nations gives us hope that countries in the world can get along together. The UN is far from perfect, but it does give a way for nations to live together in peace for the good of all people.

On March 5, 1946, at Westminster College, Winston Churchill said, “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, and all are subject, in one form or another, not only to Soviet influence but to a very high and in some cases increasing measure of control from Moscow.”

The Iron Curtain that Churchill talked about was both a real border and a border that a person felt in their mind: a border between the East and the West – between freedom and communism. Border fences, guards with guns, and especially the Berlin Wall, clearly showed how divided the two great powers were during the Cold War.

The end of World War II created the location of the Iron Curtain. As Germany was pushed out of the countries that they had taken over during the war, the Americans and the British took control of France, Belgium, the Netherlands, and Italy. But they soon gave that control back to the people of those countries. This worked well because the people of those countries saw that the allies had saved them from Germany, and they did not need the allied countries to lead them.

But Germany was different. There was no question that the Allies were going to stay in Germany to build it again themselves. As Truman, Stalin and Attlee had planned at their meeting in Potsdam, the division of Germany into East and West was a way to share this very difficult work.

In most of Europe, the border between East and West was marked by fences and border guards.

The division of Germany gave Stalin an opportunity. His army looked out for the small Germany communist party. There had been communists in Germany since the days of Marx and Engels, but the Nazis had persecuted them. Now, with the Soviets in charge, they took over control of the government.

It was the same way all across eastern Europe. In the countries that the Soviets had taken back from Germany – Poland, Czechoslovakia, Romania, Albania, Hungary, Bulgaria and East Germany – the communists took over the governments. The Soviet Army turned the economies of these countries into the kind that the Soviets had. Private people did not own farms, or factories where things were made, or businesses. These were all owned and run by the government.

The countries in western Europe went back to the free market economy that they had before the war, and they chose their own leaders. (Except for Spain, Portugal and Greece, which were ruled by dictators until the 1970s.)

The Iron Curtain that could be seen was fences and soldiers between the East and the West, especially in what was called the “inner German border” between East and West Germany. Outside of the cities, there were double fences with sharp edges. In the cities, high concrete walls were built. In the first ten years after the war people could easily travel between the East and the West. But by the end of the 1950s that was almost impossible. After the Berlin Wall was built in 1961, people from the East were shot and killed by their own border guards if they tried to escape into the West.

The division between the communist nations and those supported by the United States during the Cold War ran into Asia as well, but the words “Iron Curtain” were only used for the border in Europe.

The Iron Curtain was a real border of concrete and steel and soldiers. But even more so, it was a border in the minds of people. It was like a screen that hangs halfway across a room, or one that keeps the inside and the outside apart. The Iron Curtain cut off neighbors from each other. It was like people who lived on either side of the Iron Curtain lived in two different worlds, and they no longer got along with each other and no longer trusted each other.


After 1945, everyone could see that the United States and the Soviet Union had very different ideas about how the world should work, and that this would lead to major problems in the years to come. People wanted a way to keep from fighting with each other. Starting the United Nations showed that they wanted this, but the new United Nations could not keep the Cold War from happening.

Maybe the beginning of the Cold War was the fault of the leaders of the East and the West. If Stalin had not been the leader of the Soviet Union, would the communists have gotten along with the West as they did during the war? If Truman had not dropped the atomic bomb on Japan, would the Soviets have been less afraid of the West?

Or maybe it was more than that. Maybe the many years of war had left people afraid of other people — “us against them” so to speak. But the Cold War was the choice that people made. Couldn’t they have stopped it from happening? Or was it going to happen anyway. What do you think?



BIG IDEA: The Cold War was a conflict about what was the best economic system and split the world between the Soviet Union and the United States and the allies of these two superpowers. Many of the alliances, geographic divisions, and international systems of the Cold War are the results of the way World War II ended.

The Cold War was a 50-year struggle between the United States and the Soviet Union. The two superpowers and their allies were trying to spread their ideas about the best way to run nations. The Soviet Union was the first communist nation and wanted to spread communism. The United States believed communism was wrong and wanted to promote a free market system.

Communism, which is now almost entirely gone in the world, is a system in which everyone works, and everyone shares in the wealth of the nation. The problem is that choice is taken out of the system, and therefore, incentive is also lost. People do not work hard, and the government becomes a dictatorship.

Before World War II ended, the leaders of the United States, United Kingdom and Soviet Union met multiple times to plan what the world would look like after the fighting ended.

After World War II, most of the nations in Africa and Asia that had been European colonies became independent. Many of these nations were poor, and both the United States and Soviet Union tried to win them as allies during the Cold War. Sometimes, this led to violence.

After World War I, Woodrow Wilson had tried to create a League of Nations to help prevent future war. After World War II, the United Nations was created. This time, the United States did join, and the UN has played an important role in the world as a peacekeeper and a forum for debate.

When Germany fell and the war ended in Europe, the Americans, French, British and Soviets divided up Europe into East and West. In the lands in the East that the Soviet armies had occupied, communist governments were supported. In the West, democratic governments were encouraged. This led to a division of the continent that would last throughout the Cold War. Germany itself was divided into East and West, as was Berlin, its capital city.
