But what will matter is who China wants.
Is she China-centric enough?
If not she’ll be lucky to live.
Kim Yo-jong knows where her bread is buttered. She went to the NK military academy after she graduated in Switzerland.
That she is now as prominent in the Party, the only female member of the Politburo, is pretty much the Chinese seal of approval.
She took temporary charge of the government in 2014 when Kim Jong-un had a health “episode”.
IMVHO Kim Yo-jong is more politically astute than her brother. Probably brighter overall as well. The fact she is female has held her back so far.
The only other heirs are unknowns to the NK people.
Both China and the NK military have an interest in keeping the Kim dynasty going.
We can be sure KJU had Chinese approval when he took out his brother, though I expect they were upset with how sloppy the job was.
