Realism vs. Idealism: How American Foreign Policy Has Changed Since World War Ii

The end of the nineteenth century marked a significant change in the American foreign policy. Prior to the late 1800’s and early 1900’s, America had paid little attention to foreign affairs. When compared to some of the more powerful European countries, such as France, Germany, and Great Britain, the United States had a

Prior to World War I, the United States generally chose to follow Washington’s farewell address and stay out of “foreign entanglements”. The United States foreign policy from 1918 to 1953 shifted from isolationism or independent internationalism to a more involved internationalism and containment of communism due to various international events, economic conditions, and US public opinion.

Throughout the course of history, the United States has remained consistent with its national interest by taking many different actions in foreign policy. There have been both immediate and long term results of these actions. Foreign policy is the United States policy that defines how we deal with other countries economically and politically. It is made by congress, the president, and the people. Some of the motivations for United States foreign policy are national security, economics, and idealism. The United States entry into World War I in 1917 and the escalation of the Vietnam War in 1964 and the both had great impact on the United States.

The Truman Doctrine affected the Cold War by stopping Communists from destroying Europe any further. History.state.gov states, “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.” In his speech, he asked Congress to give support to the Greek government and go against the Communists. If the U.S. government failed to help the Greek government, the Communists would continue to damage Europe. The Truman Doctrine affected the Cold War, and another policy that affected the Cold

Throughout the mid to late twentieth century the United States was extremely concerned with their foreign policy due to mishaps that surfaced as a result of lazy administration when dealing with communism. As an example, one mishap was how the Truman Administration dealt with China after the KMT surfaced following WWII. Instead of immediately defending the People’s Republic of China, the United States stayed mostly secluded and independent and let China slip into the favor of the KMT. This was an example of the United States’ being too moderate in their foreign policy. However, on the other hand, there were examples where the United States was too aggressive in their foreign policy. An example of this was how the US chose to dealt with North

1947: Truman Doctrine: The Truman Doctrine was one of the policies under President Truman’s “Containment Policy.” In the Doctrine, he requested $400 million to bolster forces in eastern Europe to defend against Communism. Congress agrees and passes the doctrine. Dean Acheson, who was the Secretary of State at the time, argued that the fall of a Communist country will have a “domino” effect on the neighboring countries, and they need to be properly prepared for such a situation. As result of this policy, the US became the “global

The devastating WWI left a permanent mark on the European soil, as well as in American people’s minds. People now understood what real wars are like; they are not always honorable, romantic or beneficial. As a result, isolationism ran high as the postwar United States entered the 1920s. Three presidents, Warren G. Harding, Calvin Coolidge and Herbert Hoover all devoted themselves to domestic affairs starting from 1920 while trying their best to keep the country safe from the European turmoils. However, as the WWII erupted in Europe in the 1930s, president Franklin D. Roosevelt sensed the potential danger posed by Germany toward the United States. A series of changes in foreign policies from 1920 through 1941 marked the United

Truman and Eisenhower each wanted to help limit the increasing issue of communism. One approach they did was getting involved physically and militarily in the countries that were in need. The peace conference at Potsdam was a failure, because communist Russia still stood on their own and as their own separate nation. The Soviet Union had already succeeded in conquering Poland, and much of Europe splitting up Germany. After Hitler committed suicide, the main obstacle for the United States and many other countries was to avoid the looming threat of communism. Truman created the Truman Doctrine to possibly stop or postpone this issue. “I believe,” he argued, “that it must be the policy of the United States to support free people who are resisting attempted subjugation by

Harry S. Truman was President of the United States from 1945-1953. President Truman presidency was marked throughout by important foreign policy initiatives. Central to almost everything Truman undertook in his foreign policy was the desire to prevent the expansion of influence of the Soviet Union. At the end of World War II it was immediately apparent that Russia was trying to draw as many countries as it could into its influence, if not total control. The United States became extremely alarmed as country after country did indeed fall under Russia’s

Over the years 1930 through 1941 the goals of American foreign policy generally changed. In the earlier years America dealt with war and fought with other countries. America was not very smart in learning to stay out of war. Over the years, America became more neutral and attempted to stay out of war as much as possible. Throughout the years, important figures wrote documents to support America’s journey and decisions.

Throughout the Cold War, America’s foreign policy made a great difference and was very effective. Document A states that the policy towards the Soviet Union must be long-term, which America did just that. It says to keep the Soviets more of a rival than a partner, which they did very effectively. The Truman Doctrine stated that America would help other countries fight communism both politically and physically. This was very effective because it prevented the spread of communism. The Doctrine was clearly shown in Document B, where the U.S. assisted South Korea from communist North Korea.

The Korean War begun far before North Korea had launched their first assault upon South Korea. Nearing of the end of the Second World War, the Korean Peninsula had been under Japanese control. Soon enough it was liberated by both American and Soviet forces, the Soviets occupying the country north of the 38th Parallel, and the Americans south of it. After the war, neither the Koreans, Soviets, nor the Americans could agree on the country's government. This resulted in the foundation of the Republic of Korea (ROK) in the south and the Democratic People's Republic of Korea in the north (Ohn Chang-Il, 23). The fact that neither the States nor the Soviets were willing to compromise on anything was a prime factor in the separation of the Korean Peninsula.

In their book American Foreign Policy since World War 2, Steven W. Hook, and John Spanier take a historical look at American foreign policy. Since its independence, all through to the start of the 20th century, the United States had a policy of detachment. This was rooted in the believe that Europe, the only other meaningful powerful in the world in the 18th and 19th century, had intrinsic issues related to feudism that kept the continent in a constant state of war (Hook & Spanier, 2015). The U.S on its part was far away from Europe and had a unique chance to chart a different course, one free from the troubles of Europe. As a democracy free from the class systems of Europe and hence maintain peace and stability (Hook & Spanier, 2015). To maintain this peace and stability, it was in the United States interests to maintain detachment from Europe. In fact, Monroe wrote that Europe and its flawed system was evil and America should strive as much as possible to stay away from it (Hook & Spanier, 2015). However, in the 20th century, this policy of detachment was put to the test when the United States was drawn into the first and second world wars by external factors. This led the United States to get more engaged in global affairs. The idea behind engagement was to promote the ideals of democracy which, the U.S believed were the pillars of peace, as well as to protect itself from aggressors like Japan in the Second World War. After the

1. Truman’s Policy of Containment was that the U.S. would work to stop the spread of communism by providing political, economic, and military assistance to all democratic nations under the threat of communism or any external authoritarian forces. The political aspect of this policy was the alliances made during the Cold War. NATO (North Atlantic Treaty Organization) was a defensive alliance among the U.S. and other European countries against the Soviet Union. This alliance still exists today. The Warsaw Pact was a defensive alliance that included the Soviet Union and its satellite governments in Eastern Europe. These alliances assured that if one country was attacked, then the others must react by coming to the defense.

During the Cold War from 1946 to 1990 the United States had formed a policy called the containment policy which was adopted by President Harry Truman. The containment policy was a doctrine uniting military, economic, and diplomatic strategies to turn back communism and to insure that America would hold the leading role in world affairs.
