Proof of videos leading to the Vietnam War on UA-cam video and see/ listen yourself. 1) LBJ Admits assassinating Diem (1967) 2) JFK Speak of Diem Coup -Whitehouse Tapes Assassination. 3) Lyndon Johnson -Report on the Gulf of Tonkin Incident. 4) Whistleblower John White on Gulf of Incident. 5) LBJ announce Vietnam increase and rise in draft. 6) Violent racism during peaceful protests in the Civil Rights Movement. 7) President Lyndon Johnson using the N word. 8) The Truth about the Vietnam War (PragerU) 9) US bombing civilian village, actual footage 10) US troops spray Agent Orange from riverboat in Vietnam. Look up the bio Nguyễn Văn Thiệu. The South Vietnamese President that US President JF Kennedy place as President of South Vietnam after he had the former South Vietnamese catholic President, Ngô Đình Diệm and his younger brother, Ngô Đình Nhu killed. Ngô Đình Diệm was appointed by Vietnam emperor Bao Dai Nguyen and France and United States agreed to stay and support him to establish a Democratic South Vietnam. But that later change when a young Democrat name John F Kennedy became US President and his Vice President LB Johnson became America Commander in Chief. And then LB Johnson started the Vietnam War over the Gulf of Tonkin on Aug. 4, 1964. The following year after JF Kennedy sent his CIA to stage a military coup assassination on a catholic South Vietnamese President Ngô Đình Diệm. Also search and read about US President Franklin D. Roosevelt on Vietnam and see who he sent to help train the Vietminh under Ho Chi Minh against the Japanese army in the Pacific during WWII.
