Kim Il Sung (or his son? memory is hazy) had a special all-female army unit that was his literal harem. I don’t think they value women very much, outside perhaps of nepotism.
This doesn't make it a rule, but it shows there are women with power in North Korea. Because it's such an opaque country to outside observers, who knows how many more are there? Keep in mind the world didn't even know of her existence until relatively recently (about 2014).
I don't think something like this -- a woman being considered to run the country -- would be even thinkable in Iran.
It's possible North Korea had a division made up of former comfort womem at some point, but I've never heard of it and the youngest members left would be in their 80's now.
