The Vietnam War was a war that decimated the Vietnam, Laos and Cambodia regions of South-East Asia, and the US entered the war with the goal to stop the spread of Communism. Up until the GWoT, this was the longest American conflict that was one of the biggest things that were tearing apart Americans on the homefront. The war was unpopular with many and it would be one of the first times where American was at war and those that were fighting it didn't trust the government.
