I understand the Vietnam war is a sore point in America due to recruitment. But your comment is so incredibly one-sided that it's not a serious argument anymore.

The opposing party in the Vietnam war was far worse than the US on a moral level, before, during and after the war. And it wasn't a small difference. We're talking about democracy and democratically selecting laws here? Well: the large majority of the population in Vietnam, including in the North, wanted the US to defeat the Vietcong and the Soviets.

The 1954 Geneva Accords, which ended the French war, called for nationwide reunification elections by July 1956. Those elections never happened. Ngo Dinh Diem, the US-backed first president of South Vietnam who was a brutal authoritarian, refused to hold them. The US backed his refusal and kept backing him afterward.
In Eisenhower's 1963 memoir, he wrote that everyone knowledgeable he'd spoken to believed Ho Chi Minh would have taken around 80% percent of the vote if elections had happened.
The Vietnamese didn't really care about the Soviets. They are a fiercely independent and proud people with a long history of defending themselves against foreign interlopers and aggressors.
So let me restate your asinine and totally inaccurate conclusion:
The large majority of the population in Vietnam, in both the North and the South, didn't want a foreign power controlling their country and determining their fate. They wanted to run their own country, and have peace.
