Final answer:
The French were expelled from Vietnam post-WWII due to the struggle for independence, culminating in the Battle of Dien Bien Phu. Operation Frequent Wind was the U.S. evacuation from Saigon in 1975. Vietnam Veterans against the War exemplified domestic opposition to the conflict.
Step-by-step explanation:
The French were ousted from Vietnam post-World War II following a series of colonial conflicts that cumulated in the decisive Battle of Dien Bien Phu in 1954. Vietnam's struggle for independence was a significant part of the larger Indochina Wars, which involved various military campaigns aimed at ending French colonial rule. The campaign known as Operation Frequent Wind marked the final phase of the U.S. military's evacuation of American citizens and at-risk Vietnamese from Saigon, as North Vietnamese forces closed in during April 1975.
Vietnam Veterans against the War emerged as a response to the controversial war, with U.S. personnel expressing dissent and joining movements to end U.S. involvement in Vietnam. The valor demonstrated during the evacuation campaign and the subsequent asylum granted to Vietnamese refugees in the United States is a memorable aspect of the prolonged conflict.
