The Vietnam War was between the North & South Vietnam nations. With the North being a Communist regime & the South being a Democratic state in brought in the world’s Superpower like The US, USSR, and the PRA making the Vietnam War a proxy war to influence the spread of their ideologies. If the US was more friendly with the USSR & PRA then the US would have never entered the Vietnam War as “advisors” and the South would had fell more quickly with all of Vietnam being ruled un Communism.
