There is a fundamental disagreement between the US and NK.
NK wants a permanent end to the Korean War, first. That gets the UN out of the NK sanction business.
The US wants a complete and verifiable inventory of all the NK nukes and delivery systems, first.
We are at a stalemate until NK complies.
The US cannot blink, ever, or we go back to the NK wiggle and squirm game that has been going on for 65 years.
If that happens then we’re back to square one. So what? If Fat Boy keeps farting around his people continue to eat grass and dirt.
