The conflict began in 1955, took place in Vietnam, Laos and Cambodia, and officially ended in 1975 with the fall of Saigon. We know the battle well in the Western world due to the United States’ involvement from 1965 to 1973.The war in Vietnam has spawned several cinematic and literary masterpieces that often depicted the sheer depravity of what took place in the Southeast Asian country, particularly concerning the US’ involvement and ensuing mental consequences on its soldiers.
