Korean and Vietnam Wars

The Korean War was fought for about three years in the early 1950's and is sometimes referred to as the Forgotten War. It is often viewed as a struggle of Communism vs. Democracy. This war was fought in the shadow of the Cold War and the fear of the spread of Communism was a major factor for the U.S. joining in. Vietnam was also a struggle over the spread of Communism in which the North Vietnamese communist forces attempted to take over the entire country and the U.S. and South Vietnamese tried to stop them. With the Fall of Saigon in 1975, a southern stronghold, the North Vietnamese took over the country and formed the Socialist Republic of Vietnam.
