Core Findings from the National Intelligence Service
On September 10, South Korea’s National Intelligence Service (NIS) announced that it continues to assess the succession line of North Korean leader Kim Jong Un. The agency reiterated its earlier assessment that his daughter, Kim Ju Ae—approximately 13 years old—is the most probable successor. At the same time, the NIS said it is still trying to confirm whether Kim Jong Un has an older son, and it noted the existence of a younger child whose gender remains unknown. The statement emphasized that even if an older brother exists, he would not be positioned to inherit leadership.
Context of the Succession Question
Kim Jong Un assumed power after the 2011 death of his father, Kim Jong Il, continuing a three-generation male dynasty that began with Kim Il Sung in 1948. Since 2022, Kim Ju Ae has appeared publicly at high-profile events such as missile launches, a circus performance, and a visit to Beijing, signaling her rising political profile. South Korean lawmakers have previously briefed legislative committees that the NIS believes Kim Ju Ae has an elder brother, prompting the current verification effort.
Known Children and Their Public Appearances
- Kim Ju Ae – identified by state media as the “most beloved” child and referred to with the honorific “great person of guidance.” She has accompanied her father to military parades, missile tests, and diplomatic trips.
- Possible older son – unconfirmed; the NIS says he would not be in line for succession even if he exists.
- Younger sibling – gender not confirmed; the NIS acknowledges the child’s existence but provides no further detail.
Expert Views on a Female Successor
Analysts note that North Korea’s deeply patriarchal system may resist a female leader, citing the historical pattern of male heirs. Some experts warn that if Kim Ju Ae eventually marries outside the Kim family, her offspring could end the Kim dynasty’s rule. Others argue that Kim Jong Un, age 42, may still be too young to formally designate an heir, which could preserve his personal authority.
Potential Political Consequences
If Kim Ju Ae is formally groomed as successor, the regime could signal a shift in dynastic tradition, affecting internal power dynamics and the perception of North Korea abroad. Conversely, the confirmation of a male heir would reinforce the longstanding male-only succession model, likely maintaining the status quo within the ruling elite.
