Carl Gustav Horn owns Golgo 13 underwear and smokes Parliament cigarettes because it's the brand Golgo smokes. This should be more than enough proof that he was the perfect editor for Viz's 13-volume edition of Golgo 13, collecting 26 of Takao Saito's more than 500 stories of the mercenary super-sniper that have been running in Japan since 1968.
Maybe someday we'll get the complete manga series of Golgo 13 in English.
