This four- part documentary made for the History Channel, chronicles the story of America's so called "Forgotten War". As many as two million people died in the Korean War, yet it remains one of the least studied or understood conflicts of modern times. This is truly an irony, for the Korean War established the Cold War strategies that were to define the political arena for 50 years. It was the first war in which a military power was not free to unleash all its military power: the horror of the atomic weaponry which ended World War II was kept in abeyance. The political strategy that evolved in Korea became the standard for the entire Cold War-that of East and West taking opposite sides in a small divided country to promote their own political agendas. Part One explores the underlying issues that led to the invasion of South Korea by the Communist North on July 25, 1950.On June 25, 1950 North Korea surged across its southern border, catching South Korea and its allies off guard. U.S. and United Nations forces acted swiftly, but faced the likelihood of a humiliating evacuation.
