The Truman Doctrine was a foreign policy announced in 1947 that pledged economic and military aid to countries threatened by communism. Historians view this as important to the American strategy of containment in the Cold War.

The Truman Doctrine is one of the most significant events of the history of the Cold War.  The Cold War was a major world event that took place from approximately 1945 until 1990.  In general, the Cold War was a period of increased tensions and hostility between the superpowers of the United States and the Soviet Union (USSR).  The Truman Doctrine was a policy of containment by the United States against the Soviet Union, that was practiced throughout nearly the entire history of the Cold War.

TRUMAN DOCTRINE – COLD WAR

When World War II came to an end in 1945, the Allied powers (USA, Britain and the Soviet Union) held conferences to discuss how Germany should be divided up upon its defeat.  The first conference was held at Yalta in February of 1945 and the second was held at Potsdam in July of the same year.  The agreements ultimately led to the splitting of the defeated Germany into four “allied zones” with portions controlled by the Soviet Union, United States, Britain and France.  The conferences are considered by many historians to be the early stages of the Cold War since this was when tensions started to show between the former allies of the Soviet Union and the United States.

As the Allied countries liberated Europe from Nazi control and pushed the German army back into its own country, another development began to emerge.  More specifically, Joseph Stalin’s forces captured and remained control over the European territory that they ‘liberated’.  United States President Harry S. Truman, along with others, viewed this as a threat to the democratic world, because it saw the ideology of communism spreading throughout Europe.  Truman was concerned that many other nations would ‘fall’ to communism and threaten democracy around the world.

In response Truman argued that the United States and its allies should actively combat the spread of communism wherever it emerges.  Historians refer to this idea as the Truman Doctrine.  The Truman Doctrine was followed by the United States throughout the course of the Cold War and was an important reason for America’s involvement in events, such as: the Berlin BlockadeKorean War and the Vietnam War.  In general, historians refer to this as ‘containment‘ because the Truman Doctrine involved the United States trying to contain Soviet expansionism wherever it emerged.

Containment in the Cold War
Containment in the Cold War was significant because it was a major factor of American foreign policy for decades, especially in relation to conflicts, such as: Korean War and Vietnam War.

TRUMAN DOCTRINE – CONTAINMENT

The Cold War is often viewed as an ideological conflict because it displayed the difference in worldview between the two nations in terms of democracy and capitalism versus communism and dictatorship. As such, the United States and the Soviet Union differed greatly in their views of how the world should be organized following the major events of World War II.  For their part, the United States feared Soviet expansionism into regions in Europe and around the world.  As a result, the United States President at the start of the Cold War, Harry S. Truman, developed the Truman Doctrine policy in which the country would work to contain the spread of communism.

The United States, led by Harry S. Truman feared that communism as an ideology would spread throughout Europe and the rest of the world.  For example, after World War II both Greece and Turkey were facing financial crisis.  Due to their proximity to Soviet territory and the rise of communism in recent decades it was feared that the two countries might fall into the Soviet sphere of influence and become communist.  In a speech in 1947 on the crisis facing both countries Harry S. Truman stated:

“I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures. I believe that we must assist free peoples to work out their own destinies in their own way. I believe that our help should be primarily through economic and financial aid, which is essential to economic stability and orderly political processes.” 

​In this passage, Truman is promoting the idea that the United States should financially support the two nation to avoid them turning to communism.  This approach by Truman formed the basis of American foreign policy throughout the remainder of the Cold War in the form of containment, which historians refer to as the Truman Doctrine.  In conclusion, the Truman Doctrine was the idea that the United States should attempt to contain the Soviet sphere of influence and the spread of communism.  This foreign policy caused the United States to enter into conflict with the Soviet Union as it attempted to thwart Soviet expansionism in events such as: Berlin Blockade, Korean War, Vietnam War, etc.  As such, many historians view this as a cause of the Cold War because it increased tensions between the two superpowers and led to several conflicts between the two superpowers.
