"Defining Documents in American History: Vietnam War offers students a variety of tools of historical importance to study and analyze vital documents from the Vietnam War. From 1956 to 1975, the North Vietnamese Army and the Viet Cong (aided by the Soviet Union, China, and other communist allies) fought a long, bloody war for control of South Vietnam against South Vietnamese forces (aided by the United States and other anti-communist allies). The war lasted twenty years and left countless causalities and severe destruction in its wake, sparking international anti-war movements and controversy about U.S. involvement."--Publisher website.
