Answer:
Public support; governmental.
Step-by-step explanation:
The Vietnam War is also referred to as the Second Indochina War and it started on the 1st of November, 1955 in several locations including Cambodia, Laos and Vietnam.
Basically, the war pitted South Vietnamese communists, Vietcong and the government of North Vietnam against South Vietnam and its principal ally, which was the United States of America. During the war, President Dwight D. Eisenhower sent military advisors and aid in allegiance to South Vietnam.
In the Geneva Convention that held in 1954, Vietnam was divided into two (2); North and South. Also, the Vietnam war was escalated by President Lyndon B. Johnson.
Furthermore, there was a credibility gap between the media and the government, as there were so many contradictions between what the media reported and the government's report with respect to the war.
Hence, as the Vietnam war dragged on, public support waned because many believed that government was not telling the truth about the war.
