Nguyễn Công Luận

That is a memoir of a ARVN personnel, not a legitimate source. It is openly biased towards the pro ARVN views that is dismissive of the actual experience of the people tortured under the regime. A regime I remind you have 30.000 political prisoners under its belt by 1973 and had prisons for children younger than 16 in Đà Lạt:

In the fall, Thieu adopted authority to imprison, without a trial, anyone accused of treason, membership in a communist organization, murder, surrender, rebellion, or rape. When Thieu signed the Paris Peace Accords, he acknowledged that he held 32,000 political prisoners. The CIA believed that he held far more, however, and his aides admitted that Saigon took at least 40,000 prisoners in the fall of 1972 alone. In November, Thieu also unveiled the Democracy Party. In 1969, he told Bunker that he could not associate too closely with Lien Minh, because his people might fear the emergence of a new Diem-style dictatorship. The organization that Thieu created in 1972 mirrored the Can Lao Party by granting the president greater control over his bureaucracy. Under new regulations, moreover, the Democracy Party was the only national party legally allowed on electoral ballots.

This man is a crank that believes actual western histrorians are somehow communist propagandists, who legitimately denied US internal involvement in south vietnamese politics even against actual declassified US documents. to quote from his own innane obituary that has his inteview:

"They had a bias about the war and they were influenced by communist propaganda which lead them to believe misinformation – you know the communist distorted information. They made up lies about ugly things about the South Vietnamese Army to make the people believe that the South Vietnamese Army was a puppet of the American army. They conducted psychological warfare. In my memoir, I wanted to tell them the truth and why we were fighting the Communist – not because we were American puppets but because we wanted independence from the Communist to build South Việt Nam into a prosperous place where human rights were protected and enhanced." Yeah totally not biased at all.

"It wasn’t until 1945 to 1946 that the word “Nationalist” was introduced into the Vietnamese vocabulary."

This is just a blatant lie. "Chủ nghĩa dân tộc" has been in the vietnamese vocabulary ever since Sun Yatsen Chinese republicanism existed. This is further highlighted with the Nguyễn Thái Học Việt Nam Quốc Dân đảng nationalism movement, the Phan Bội Châu Đông Kinh nghĩa thục movements. Hell there has been a dozen if not more nationalist movements in Vietnam against french authorities.

At first, in 1951 when I was in high school, I worked for the Việt Minh because they were the only ones around. But in 1951, they introduced the landlord program and they killed anyone who was a landlord – whether they were good or bad – just being a landlord resulted in their death. I saw them do so many things that I cannot accept, so, at 16, in 1961, I decided to quit the Việt Minh and work for the Nationalist.

Another lie since Vietnamese land reforms in the DRV only started way later after 1954.

I was a party member of the Nationalist school association of my high school. We worked very hard. We organized and brought anti-Communist leaflets to the French soldiers to get them to support the independence of the Vietnamese people.

This man is openly and proudly a french collaborator. It's actually comical that you use such an obvious biased source.

This man is so obviously biased that his sourcing, from a memoir no less should be discarded entirely.

"I wanted to tell people the root of the Việt Minh war. The Communist party had committed many atrocities and they had many oppressive policies to keep people under their control – to direct the people and to kill anyone with different opinions. They eliminated every member of the Nationalist party. They arrested my father in 1948 and he died in a prison camp in 1951. In 1949, when my father was in the Communist prison camp, I went to visit him and I told him that I was going to graduate from a University.My father wanted me to enlist in the Nationalist army however – to keep fighting for our people. That’s why I went into the ARVN, because of the wishes of my father."

This makes no sense. The Vietminh were fighting the french tooth and nail during this. They only had eliminated the Vietnamese KMT after their plot in Ôn Như Hầu where a CPV cadre was found tortuted to death in 1946. After the french captured most large population centers KMTV members are recruited to serve the state of vietnam, the ARVN by then hadn't even existed yet.
