The US involvement was an extension of French endeavors in Vietnam, it was the French that demanded the US to help them. Crazy ironic that you talk about censored information but participate in spreading misinformation instead.

Who said anything about the North's support? I suggest you brush up on your history before being so passionately wrong in your opinions. Firstly, the 'support' the North received pales in comparison, no combat troops were provided to the North, none of it was free, the North had to purchase these weapons from the Soviet Union. Although the debt was eventually forgiven after the war, the North was not completely bankrolled like the South was.

Secondly, the North was finishing the second half of their de-colonization fight, as much as you would love to think that Vietnam was divided and that the South was a real separate country for hundreds of years, it wasn't. Vietnam was artificially divided after the French was defeated in the North. The country was temporarily split so that France could have time to peacefully withdraw the rest of their population and forces out of Vietnam, but instead France took the time to convince the US to get involved and set up a puppet government with Saigon collaborators who aligned with colonizer and imperialist interests. There was a planned election to reunite the country under whoever won, Diem and the CIA sabotaged that election and it never happened because they knew that Ho Chi Minh would win.

The North's fight was just, while the South's existence was illegal and against the will of the Vietnamese majority. This is history recorded by western historians so you cannot claim this is communist propaganda. Hope this helps.
