North Korea has publicly admitted that it has nuclear weapons. But beyond the country’s escalating nuclear brinkmanship with the U.S., very little else is known about its closed society.

A new book by Asia-based foreign correspondent Bradley Martin peels away some of the layers shielding the country. “Under the Loving Care of the Fatherly Leader: North Korea and the Kim Dynasty” chronicles the methods of indoctrinating children, the brutality of the gulags, and the peccadilloes of North Korea’s rulers.

Hear a conversation about North Korea’s nuclear weapons and everyday life in the self-isolated, hard-line Communist state.

Bradley K. Martin, author of “Under the Loving Care of the Fatherly Leader: North Korea and the Kim Dynasty”
