Rare Earth Minerals.
They got’em. We need ‘em.
They have a huge hollowed out mountain from nuke testing. That would make a nice dumpsite for nuclear waste materials that are piling up here in the USA. They take it off our hands, we pay them, a win-win situation.
Every family in North Korea gets 5lbs of meat per week, modern medicine, a basic car, a monthly bag of rice and sufficient cabbage for kimchi and we get 60% of the minerals. Deal?
