North Korea has no incentive to speak to The West. It has nuclear capacity now with missiles that reach the USA. North Korea is not planning on giving that up. Un won’t use it against South Korea because he wants to unit the North and South. That will be the aspiration of the North forever.
Un’s idea of uniting with the South is to maintain leadership as he has nuclear missiles and the South would disarm from them. In sees any disarmament as opening up danger to all Koreans.
North Korea has amusement parks now along with many impoverished. It sees these western cultural achieves as an advancement.
Un’s sister has also stated in the past South Korean activists were responsible for infecting North Korea with the current SARS virus. She complained South Korea did nothing to stop the activists. I think she has a point in that in a global pandemic activists by principle alone should not be flying balloons over the border. That is just a global standard. For all we know the North Korean citizens that receive the packages from the South might actually welcome the contact as if family.
So, while The West sees nothing wrong with allies meeting for whatever the reason, North Korea does. Has anyone welcomed an invited North Korean delegation to the meetings? Perhaps that would mean real in roads if the North was welcomed to meet with the South and it’s friends.
