I think Ambassador Harris should troll the Korean leftists by growing out his mustache to look like Choi Jin-dong:

In the black-and-white photo, two men wearing mustaches pose proudly in military uniforms with guns at their waists. The taller man on the left has been confirmed as independence fighter Hong Beom-do. But the identity of the short and stout man standing next to Hong has been shrouded in mystery for decades. Recently the identity of the mam was confirmed to be independence fighter Choi Jin-dong. / Courtesy of Ban Byung-yool

You can read the whole story about how Choi Jin-dong was identified at this link. The picture was taken in Moscow during a communist conference and the guns both are wearing were actually gifts from Lenin.
