The Korean War had its day and it wasn’t as dark and negative as the media treatment of Vietnam.
Vietnam is so dark that if you think back to the modern sitcoms and cartoon shows with the dad, or uncle being a war vet, none of them were ever Vietnam vets, instead they would make him a Korean War vet, is grandpa ever a Vietnam vet, even now?
Don't remember any in TV shows, but many movies are based on Vietnam Vets.
