Kim Yo-jong, his sister, is the closest thing to an heir he has. Not good news for North Korea if true.
From a Guardian article published just yesterday:
As the world grapples with the coronavirus pandemic – with Pyongyang continuing to insist it has not recorded a single case – Kim Yo-jong’s ascendancy continues.
Last month, she made her first public statement, condemning the South as a “frightened dog barking” after Seoul protested against a live-fire military exercise by the North. And in March, she publicly praised Donald Trump for sending Kim a letter in which he said he hoped to maintain good bilateral relations and offered help in dealing with the coronavirus pandemic.
The publication of political statements in Kim Yo-jong’s name underlines her central role in the regime, according to Youngshik Bong, a research fellow at Yonsei University’s Institute for North Korean Studies in Seoul. “It is revealing that Kim Jong-un permitted her to write and announce a scathing statement about South Korea in such a personal tone,” Bong said. “He is clearly ready to allow his sister to become his alter ego.”
A ruthless dictator woman would be an interesting change of pace. Also, she's younger than I am, and I haven't managed to oppress anyone yet
