Answer:
B. The assassination gave the U.S. government an opportunity to support a new military government in South Vietnam.
Step-by-step explanation:
The assassination of Ngo Dinh Diem had a significant impact on U.S. support in South Vietnam. The correct answer is B. The assassination gave the U.S. government an opportunity to support a new military government in South Vietnam.
Ngo Dinh Diem was the President of South Vietnam and a key U.S. ally during the Vietnam War. However, his government was criticized for being corrupt and repressive, which led to growing unrest and protests among the South Vietnamese population.
In November 1963, a coup d'état orchestrated by South Vietnamese military officers overthrew and assassinated Ngo Dinh Diem and his brother Ngo Dinh Nhu. The U.S. government had provided significant support to Diem's government, and his assassination created a power vacuum in South Vietnam.
The U.S. government saw an opportunity to support a new military government in South Vietnam, as they believed it would be more stable and better able to fight against the communist insurgency. The U.S. government provided support to the new government led by General Duong Van Minh, who became the new leader of South Vietnam.
However, the instability and political turmoil in South Vietnam continued, and the U.S. involvement in the conflict escalated. The assassination of Ngo Dinh Diem and the subsequent events in South Vietnam ultimately proved to be a turning point in the Vietnam War, leading to increased opposition to the war in the United States and around the world.
