The United States didn't fight against South Vietnam in fact they were allies fighting against North Vietnam.
Vietnam wasn't fighting anybody in 1964 because there was no country named Vietnam. There were two nations, one called North Vietnam and another called South Vietnam. Just like the states North Carolina and South Carolina or North Dakota and South Dakota in America...FOUR separate states! In 1964 North Vietnam became engaged in war with America; after the Tonkin Gulf naval battle(s) in August 1964.
Militarily, the forces of North Vietnam (including South Vietnamese sympathizers known as the Viet Cong) were the only units fighting against the U.S. China and Russia both provided material support to the Hanoi government.
America "Helped" Vietnam against "the communists" and i think that's it.
