I'm going to assume that the NORK cadre of generals and other high-up government types are some of the least-woke people on the planet and are thus sexist beyond anything we might see in the west.
So they might well resent having to take orders from a woman and might dispose of her quickly.
If they do depends on what she has over them. Maybe it's enough to keep her in power, but then, maybe not.
And if she goes and another Kim doesn't step up we could see a civil war break out amongts the crime families that make up the Nork government.
And won't that be fun?
