Truman Doctrine
The Truman Doctrine was a policy set forth by the U.S. President Harry S Truman in a speech on March 12, 1947 stating that the U.S. would support Greece and Turkey with economic and military aid to prevent their falling into the Soviet sphere. Historians often consider it as the start of the Cold War.
Truman stated the Doctrine would be "the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures." Truman reasoned, because these "totalitarian regimes" coerced "free peoples," they represented a threat to international peace and the national security of the United States. Truman made the plea amid the crisis of the Greek Civil War (1946–1949). He argued that if Greece and Turkey did not receive the aid that they urgently needed, they would inevitably fall to communism with grave consequences throughout the region.
The Doctrine was informally extended to become the basis of American Cold War policy throughout Europe and around the world. It shifted American foreign policy toward the Soviet Union from détente (a relaxation of tension) to, as George F. Kennan phrased it, a policy of containment of Soviet expansion.
United Nations
The United Nations (UN) is an international organization whose stated aims are facilitating cooperation in international law, international security, economic development, social progress, human rights, and achievement of world peace. The UN was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue. It contains multiple subsidiary organizations to carry out its missions.
There are 193 member states, including every internationally recognized sovereign state in the world but Vatican City. From its offices around the world, the UN and its specialized agencies decide on substantive and administrative issues in regular meetings held throughout the year. The organization has six principal organs: the General Assembly (the main deliberative assembly); the Security Council (for deciding certain resolutions for peace and security); the Economic and Social Council (for assisting in promoting international economic and social cooperation and development); the Secretariat (for providing studies, information, and facilities needed by the UN); the International Court of Justice (the primary judicial organ); and the United Nations Trusteeship Council (which is currently inactive). Other prominent UN System agencies include the World Health Organization (WHO), the World Food Programm (WFP) and United Nations Children's Fund (UNICEF). The UN's most prominent position is Secretary-General which has been held by Ban Ki-moon of South Korea since 2007.
The United Nations Headquarters resides in international territory in New York City, with further main offices at Geneva, Nairobi, and Vienna. The organization is financed from assessed and voluntary contributions from its member states, and has six official languages: Arabic, Chinese, English, French, Russian, and Spanish
Korean War
The Korean War (25 June 1950 – 27 July 1953) was a war between the Republic of Korea (supported primarily by the United States of America, with contributions from allied nations under the aegis of the United Nations) and the Democratic People's Republic of Korea (supported by the People's Republic of China, with military and material aid from the Union of Soviet Socialist Republics). The Korean War was primarily the result of the political division of Korea by an agreement of the victorious Allies at the conclusion of the Pacific War at the end of World War II. The Korean peninsula was ruled by the Empire of Japan from 1910 until the end of World War II. Following the surrender of the Empire of Japan in September 1945, American administrators divided the peninsula along the 38th parallel, with U.S. military forces occupying the southern half and Soviet military forces occupying the northern half.
