Vietnam Myths

Op-for has a good recap of some common Vietnam myths.
Some highlights (emphasis mine):

Isolated atrocities committed by American Soldiers produced torrents of outrage from anti-war critics and the news media while Communist atrocities were so common that they received hardly any media mention at all. The United States sought to minimize and prevent attacks on civilians while North Vietnam made attacks on civilians a centerpiece of its strategy. Americans who deliberately killed civilians received prison sentences while Communists who did so received commendations. From 1957 to 1973, the National Liberation Front assassinated 36,725 Vietnamese and abducted another 58,499. The death squads focused on leaders at the village level and on anyone who improved the lives of the peasants such as medical personnel, social workers, and school teachers. - Nixon Presidential Papers Common Myths Dispelled: Myth: Common Belief is that most Vietnam veterans were drafted.
