The "Vietnam Experience" refers to the period during the Vietnam War, which lasted from 1955 to 1975. This conflict involved the United States supporting the government of South Vietnam against the communist forces of North Vietnam and the Viet Cong. The war had significant social, political, and economic impacts on both Vietnam and the U.S., leading to widespread protests and changes in military strategy. The aftermath of the war saw Vietnam reunified under communist control, resulting in major changes in the country's governance and economy. The experience also shaped U.S. foreign policy and public perception of military engagement, influencing future conflicts and the way veterans were treated upon returning home.
