North Korean leader Kim Jong Un is reportedly grooming his young daughter Kim Ju-ae, aged between 10 to 12, as his successor amidst growing concerns about his health. South Korean intelligence agencies have observed that she is being trained for leadership, evidenced by her increased presence at public and military events. Kim Jong Un, known for his obesity, smoking, and drinking, weighs around 140kg and suffers from high blood pressure and diabetes, placing him at high risk for heart disease. The North Korean regime is carefully monitoring public reactions to Kim Ju-ae's role, adjusting her exposure accordingly. Although she appears to be the front-runner, the possibility of another sibling emerging as a potential alternative has not been ruled out. This succession plan continues the Kim family's hereditary rule, which has been in place since the country's founding in 1948.
