Vietnam is a country in Southeast Asia.
After World War II, the Vietnamese communists engaged in a protracted war with France for independence. France agreed to cede control of the area, leaving northern part of the country under communists and the southern part under a unitary anti-communist republic. The North tried to overthrow the South by supporting the Viet Cong insurgency, eventually escalating into the Vietnam War, which dragged the United States of America in to deter the expansion of Soviet influence. The United States however was eventually forced out withdraw and the country reunited with fall of South Vietnam.
