The North was fighting the US; the South was allied to the US.
North VN vs South VN; US helped the South.
The United States where fighting the North Vietnamese Army to deter communism in South Vietnam. The Chinese also were a part of the conflict however not so much as a direct entity as a funding source for the NVA.
The US helped the SOUTH Vietnamese. The North was the enemy!
NVAF (North Vietnamese Air Force) and NVA (North Vietnamese Army); plus VC (Viet Cong) units living in South Vietnam.
France, Australia, US, North Vietnamese (Vietcong), South Vietnamese.
The US wasn't fighting the Vietnamese. The US was fighting the communist NORTH Vietnamese. The SOUTH Viets were friends of the US.
The US was on the SOUTH Vietnamese side. The enemy was the NORTH Vietnamese...two separate countries. The Southerners were non-communist; the Northerners were communists.
Very. Since the US brought massive military force to bear, during the Vietnam War, there would have been no possibility of a successful insurgency against the south, without the equally massive commitment of North Vietnam and its own ally, the Soviet Union.
If they weren't communists, the US would've minded its own business. But since they were Reds...they had to be stopped!
Australia was the south's ally. Along with the US, etc.
North Vietnam & loca VC; supplied by USSR/Chinese Communists against the US/Australians/New Zealanders/South Koreans/South Vietnamese/Thailand/Philippines.
The north wanted the US out, the south wanted the US to stay.
