North Korean leader Kim Jong Un and his daughter Kim Ju Ae were photographed firing pistols at a large arms factory producing light weapons.Analysts suggest these images, along with other recent public appearances, are part of an effort to cultivate Kim Ju Ae's image as a strong military leader and signal her potential succession.The publicized events follow a series of high-profile activities, including missile test observations, underscoring the regime's focus on militarized succession planning.
