Tensions between communist and non-communists parties began to brew more quickly. Many wanted to prevent another from happening. On October 24, 1945 the UN was formed. Its aim was to promote world peace. This was very difficult to achieve in the early years of the Cold War.

In a popular speech by British Prime Minister Winston Churchill, he used the term "iron curtain". He was describing an imaginary boundary in Europe dividing Western and Eastern Europe. Western Europe was filled with capitalist-democratic nations. While Eastern Europe was controlled by the communist Soviets. They restricted all types on contact and travel.

On May 1 1960, a U.S U-2  spy plane was shot down by Soviet Air Defense Forces. A CIA pilot named Francis Gary Powers had been recruited for a top secret mission. He had to fly into deep Russia to photograph denied territory. When the sophisticated spy plane was caught on U.S.S.R radar, it was shot down and Francis was captured. He was sentenced to 10 years in U.S.S.R prison. Yet he was released early when the U.S exchanged a Soviet spy for Francis.

NATO stands for North Atlantic Treaty Organization. It was formed on April 4, 1949. It was a formal alliance between Europe and North America. They would help defend each other from possible communist Soviet invasions or attacks. Countries like France, Iceland, Turkey, and Norway were apart of NATO.

In 1949, the prospect of further Communist expansion prompted the United States and 11 other Western nations to form the North Atlantic Treaty Organization (NATO). The Soviet Union and its affiliated Communist nations in Eastern Europe founded a rival alliance, the Warsaw Pact, in 1955. The alignment of nearly every European nation into one of the two opposing camps formalized the political division of the European continent that had taken place since World War II (1939-45). This alignment provided the framework for the military standoff that continued throughout the Cold War (1945-91).

A Divided Europe

Conflict between the Western nations (including the United States, Great Britain, France and other countries) and the Communist Eastern bloc (led by the Union of Soviet Socialists Republics or USSR) began almost as soon as the guns fell silent at the end of World War II (1939-45). The USSR oversaw the installation of pro-Soviet governments in many of the areas it had taken from the Nazis during the war. In response, the U.S. and its Western allies sought ways to prevent further expansion of Communist influence on the European continent. In 1947, U.S. leaders introduced the Marshall Plan, a diplomatic initiative that provided aid to friendly nations to help them rebuild their war-damaged infrastructures and economies.

Did you know? NATO continued its existence beyond the Cold War era and gained new member nations in Eastern Europe during the late 1990s. That development was not well received by leaders of the Russian Federation and became a source of post-Cold War tension between the East and the West.

Events of the following year prompted American leaders to adopt a more militaristic stance toward the Soviets. In February 1948, a coup sponsored by the Soviet Union overthrew the democratic government of Czechoslovakia and brought that nation firmly into the Communist camp. Within a few days, U.S. leaders agreed to join discussions aimed at forming a joint security agreement with their European allies. The process gained new urgency in June of that year, when the USSR cut off ground access to Berlin, forcing the U.S., Britain and France to airlift supplies to their sectors of the German city, which had been partitioned between the Western Allies and the Soviets following World War II.

NATO: The Western Nations Join Forces

The discussions between the Western nations concluded on April 4, 1949, when the foreign ministers of 12 countries in North America and Western Europe gathered in Washington, D.C., to sign the North Atlantic Treaty. It was primarily a security pact, with Article 5 stating that a military attack against any of the signatories would be considered an attack against them all. When U.S. Secretary of State Dean Acheson (1893-1971) put his signature on the document, it reflected an important change in American foreign policy. For the first time since the 1700s, the U.S. had formally tied its security to that of nations in Europe-the continent that had served as the flash point for both world wars.

The original membership of the North Atlantic Treaty Organization (NATO) consisted of Belgium, Britain, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal and the United States. NATO formed the backbone of the West's military bulwark against the USSR and its allies for the next 40 years, with its membership growing larger over the course of the Cold War era. Greece and Turkey were admitted in 1952, the Federal Republic of Germany (West Germany) in 1955 and Spain in 1982. Unhappy with its role in the organization, France opted to withdraw from military participation in NATO in 1966 and did not return until 1995.

Warsaw Pact: The Communist Alliance

The formation of the Warsaw Pact was in some ways a response to the creation of NATO, although it did not occur until six years after the Western alliance came into being. It was more directly inspired by the rearming of West Germany and its admission into NATO in 1955. In the aftermath of World War I and World War II, Soviet leaders felt very apprehensive about Germany once again becoming a military power-a concern that was shared by many European nations on both sides of the Cold War divide.

In the mid-1950s, however, the U.S. and a number of other NATO members began to advocate making West Germany part of the alliance and allowing it to form an army under tight restrictions. The Soviets warned that such a provocative action would force them to make new security arrangements in their own sphere of influence, and they were true to their word. West Germany formally joined NATO on May 5, 1955, and the Warsaw Pact was signed less than two weeks later, on May 14. Joining the USSR in the alliance were Albania, Bulgaria, Czechoslovakia, the German Democratic Republic (East Germany), Hungary, Poland and Romania. This lineup remained constant until the Cold War ended with the dismantling of all the Communist governments in Eastern Europe in 1989 and 1990.

Like NATO, the Warsaw Pact focused on the objective of creating a coordinated defense among its member nations in order to deter an enemy attack. There was also an internal security component to the agreement that proved useful to the USSR. The alliance provided a mechanism for the Soviets to exercise even tighter control over the other Communist states in Eastern Europe and deter pact members from seeking greater autonomy. When Soviet leaders found it necessary to use military force to put down revolts in Hungary in 1956 and in Czechoslovakia in 1968, for example, they presented the action as being carried out by the Warsaw Pact rather than by the USSR alone.

The Truman Doctrine was established on March 12,1947 by President Harry S. Truman. This doctrine stated nations that it would help provide military, economic, and political help to democratic nations. It would stop the spread of authoritarian or communist nations. This doctrine provided aid to countries like Greece and Turkey from pressure from the Soviet expansion.

With the Truman Doctrine, President Harry S. Truman established that the United States would provide political, military and economic assistance to all democratic nations under threat from external or internal authoritarian forces. The Truman Doctrine effectively reoriented U.S. foreign policy, away from its usual stance of withdrawal from regional conflicts not directly involving the United States, to one of possible intervention in far away conflicts.

The Truman Doctrine arose from a speech delivered by President Truman before a joint session of Congress on . The immediate cause for the speech was a recent announcement by the British Government that, as of March 31, it would no longer provide military and economic assistance to the Greek Government in its civil war against the Greek Communist Party. Truman asked Congress to support the Greek Government against the Communists. He also asked Congress to provide assistance for Turkey, since that nation, too, had previously been dependent on British aid.

At the time, the U.S. Government believed that the Soviet Union supported the Greek Communist war effort and worried that if the Communists prevailed in the Greek civil war, the Soviets would ultimately influence Greek policy. In fact, Soviet leader Joseph Stalin had deliberately refrained from providing any support to the Greek Communists and had forced Yugoslav Prime Minister Josip Tito to follow suit, much to the detriment of Soviet-Yugoslav relations. However, a number of other foreign policy problems also influenced President Truman's decision to actively aid Greece and Turkey. In 1946, four setbacks, in particular, had served to effectively torpedo any chance of achieving a durable post-war rapprochement with the Soviet Union: the Soviets' failure to withdraw their troops from northern Iran in early 1946 (as per the terms of the Tehran Declaration of 1943); Soviet attempts to pressure the Iranian Government into granting them oil concessions while supposedly fomenting irredentism by Azerbaijani separatists in northern Iran; Soviet efforts to force the Turkish Government into granting them base and transit rights through the Turkish Straits; and, the Soviet Government's rejection of the Baruch plan for international control over nuclear energy and weapons in June 1946.

In light of the deteriorating relationship with the Soviet Union and the appearance of Soviet meddling in Greek and Turkish affairs, the withdrawal of British assistance to Greece provided the necessary catalyst for the Truman Administration to reorient American foreign policy. Accordingly, in his speech, President Truman requested that Congress provide $400,000,000 worth of aid to both the Greek and Turkish Governments and support the dispatch of American civilian and military personnel and equipment to the region.

Truman justified his request on two grounds. He argued that a Communist victory in the Greek Civil War would endanger the political stability of Turkey, which would undermine the political stability of the Middle East. This could not be allowed in light of the region's immense strategic importance to U.S. national security. Truman also argued that the United States was compelled to assist "free peoples" in their struggles against "totalitarian regimes," because the spread of authoritarianism would "undermine the foundations of international peace and hence the security of the United States." In the words of the Truman Doctrine, it became "the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures."

Truman argued that the United States could no longer stand by and allow the forcible expansion of Soviet totalitarianism into free, independent nations, because American national security now depended upon more than just the physical security of American territory. Rather, in a sharp break with its traditional avoidance of extensive foreign commitments beyond the Western Hemisphere during peacetime, the Truman Doctrine committed the United States to actively offering assistance to preserve the political integrity of democratic nations when such an offer was deemed to be in the best interest of the United States.

After WW2 the U.S,British,and Soviet military all divided and occupied Germany. Later, the Soviets would block all railway,canal, and road access of Berlin under Western control. In response, the U.S does a huge airlift of medicine,food, and water to citizens in the city. This lasted for nearly a year. It ended on May 12, 1949 when Soviets admitted defeat and lifted the blockade.

4. The Berlin Airlift: The End of the Blockade

After World War II, the Allies partitioned the defeated Germany into a Soviet-occupied zone, an American-occupied zone, a British-occupied zone and a French-occupied zone. Berlin, the German capital city, was located deep in the Soviet zone, but it was also divided into four sections. In June 1948, the Russians-who wanted Berlin all for themselves-closed all highways, railroads and canals from western-occupied Germany into western-occupied Berlin. This, they believed, would make it impossible for the people who lived there to get food or any other supplies and would eventually drive Britain, France and the U.S. out of the city for good. Instead of retreating from West Berlin, however, the U.S. and its allies decided to supply their sectors of the city from the air. This effort, known as the "Berlin Airlift," lasted for more than a year and carried more than 2.3 million tons of cargo into West Berlin.

The Berlin Airlift: The Partitioning of Berlin

As World War II came to an end in 1945, the Allied powers held peace conferences at Yalta and Potsdam to determine how they would divide up Germany's territories. The agreements split the defeated nation into four "allied occupation zones": They gave the eastern part of the country to the Soviet Union and the Western part to the U.S. and Great Britain. In turn, those nations agreed to cede a small part of their territories to France.

Did you know? During the Berlin airlift, an Allied supply plane took off or landed in West Berlin every 30 seconds. The planes made nearly 300,000 flights in all.

Even though Berlin was located entirely within the Soviet part of the country (it sat about 100 miles from the border between the eastern and western occupation zones), the Yalta and Potsdam agreements likewise split the German capital into Allied sectors: The Soviets took the eastern half, while the other Allies took the western. This occupation of Berlin, governed by a multipower agency called the Kommandatura, began in June 1945.

The Soviets were dissatisfied with this arrangement. Twice in recent memory, they had been invaded by Germany, and they had no interest in promoting that country's reunification-yet it seemed that was exactly what the United States, Great Britain and France had in mind. For example, in 1947 the Americans and the British combined their two sectors into a single "Bizonia," and the French were preparing to join as well. In 1948, the three western Allies created a single new currency (the Deutsche Mark) for all of their occupation zones-a move that the Soviets feared would fatally devalue the already hyperinflated Reichsmarks that they used in the east. For the Soviets, it was the last straw.

The Berlin Airlift: The Berlin Blockade

The Russians were also concerned about a unified West Berlin: a capitalist city located right in the middle of their occupation zone that would likely be powerfully and aggressively anti-Soviet. They decided that something needed to be done to stop this creeping unificationism. They withdrew from the Kommandatura and began a blockade of West Berlin, a maneuver that they hoped would effectively starve the western powers out of Berlin. If West Germany was to become its own country, they argued, then Berlin, located more than 100 miles from its border, could no longer be its capital.

On June 24, 1948, the Soviet authorities announced that the Autobahn, the highway connecting western Germany to Berlin, would be closed indefinitely "for repairs." Then, they halted all road traffic from west to east, and barred all barge and rail traffic from entering West Berlin. Thus began the blockade of Berlin.

As far as the western Allies were concerned, withdrawal from the city was not an option. "If we withdraw," said the American military commander, "our position in Europe is threatened, and Communism will run rampant." President Harry Truman echoed this sentiment: "We shall stay," he declared, "period." Using military force to strike back against the Soviet blockade seemed equally unwise: The risk of turning the Cold War into an actual war-even worse, a nuclear war-was just too great. Finding another way to re-provision the city seemed to the Allies to be the only reasonable response.

The Berlin Airlift: "Operation VITTLES" Begins

It was quickly settled: The Allies would supply their sectors of Berlin from the air. Allied cargo planes would use open air corridors over the Soviet occupation zone to deliver food, fuel and other goods to the people who lived in the western part of the city. This project, code-named "Operation VITTLES" by the American military, was known as the "Berlin airlift." (West Berliners called it the "Air Bridge.")

The Berlin airlift was supposed to be a short-term measure, but it settled in for the long haul as the Soviets refused to lift the blockade. For more than a year, hundreds of American, British and French cargo planes ferried provisions from Western Europe to the Tempelhof (in the American sector), Gatow (in the British sector) and Tegel (in the French sector) airfields in West Berlin. At the beginning of the operation, the planes delivered about 5,000 tons of supplies to West Berlin every day; by the end, those loads had increased to about 8,000 tons of supplies per day. The Allies carried about 2.3 million tons of cargo in all over the course of the airlift.

Life in West Berlin during the blockade was not easy. Fuel and electricity were rationed, and the black market was the only place to obtain many goods. Still, most West Berliners supported the airlift and their western allies. "It's cold in Berlin," one airlift-era saying went, "but colder in Siberia."

The Berlin Airlift: The End of the Blockade

By spring 1949, it was clear that the Soviet blockade of West Berlin had failed. It had not persuaded West Berliners to reject their allies in the West, nor had it prevented the creation of a unified West German state. (The Federal Republic of Germany was established in May 1949.) On May 12, 1949, the Soviets lifted the blockade and reopened the roads, canals and railway routes into the western half of the city. The Allies continued the airlift until September, however, because they wanted to stockpile supplies in Berlin just in case the blockade was reinstated.

Most historians agree that the blockade was a failure in other ways, too. It amped up Cold War tensions and made the USSR look to the rest of the world like a cruel and capricious enemy. It hastened the creation of West Germany, and, by demonstrating that the U.S. and Western European nations had common interests (and a common foe), it motivated the creation of the North Atlantic Treaty Organization (NATO), an alliance that still exists today.

Europe was let in ruins and devastation after WW2. The Marshall plan initiative was passed in 1948. Another name for it was the European Recovery Program. The U.S gave $12 billion to Western Europe to help rebuild European economics. They also sent things such as fuel,machinery,food and money. At least 17 countries were apart of the ERP. The Marshall Plan was very effective. It promoted peace,friendship, and continued to contain the Soviet expansion.
