There is an anecdote showing just how ignorant Kim Young-sam was

During the 1987 presidential candidate debate hosted by the Kwanhun Club, editorial writer Hong In-geun of the Dong-A Ilbo asked:
"You mentioned making the area a nuclear-free zone; does that include tactical nuclear weapons as well?"
Kim Young-sam's response:
"Are you talking about nuclear reactors?"
Editorial writer Hong In-geun was taken aback. Calling nuclear weapons "nuclear reactors."
"I mean tactical nuclear weapons, nuclear weapons."
Kim Young-sam continued to miss the point and talk about irrelevant things. Eventually, frustrated by Hong's repeated questioning, Kim Young-sam snapped:
"Ah, I said I don't know, so why do you keep pushing me?"
Was his idea of a nuclear-free zone simply not building nuclear power plants in the Demilitarized Zone??
