After World War II and the swiftly following Korean War, America entered a time of relative peace. However, starting in 1955, a conflict in Vietnam would eventually drag America into war once again. Throughout the 1960’s and early 1970’s, America had a large military presence in Vietnam as a result of the Truman Doctrine. The Vietnam War, which ran from 1955 to 1975, was a conflict between the forces of capitalism and those of communism and was part of the overall Cold War pattern of indirect confrontation. This war fundamentally changed the relationship between American citizens and their government, as the citizenry vocally and violently did not support the conflict while the American government supported it passionately. The draft was still in force during most of the conflict, meaning that young men could be made to go to war, regardless of their opinions about the matter. Because the war was a guerilla war, the tactics used were often grotesque, and seen as immoral. As more and more soldiers were killed in the fight to control the jungle (where most of the conflict took place), the American people became angrier and angrier with the American government for being unresponsive to the will of the people. This distrust of government shaped the attitudes of many Americans in the 1970’s and 1980’s, and this was felt particularly strongly in music, where the theme of rebellion was championed. In 1975, the communist forces of North Vietnam overran the capitalistic South Vietnam, unifying the country under the banner of communism. This was perhaps the most difficult defeat in war for America since early battles of the American Revolution.
