There are no preconditions, as Trump insisted.
Other than a commitment to nuclear disarmament.
This is a good thing. And progress.
Yeah, it may not pan out, but Norklandia now knows if it does not they will cease to exist.
This is Trump preparing the American people for the coming war. Showing he is sincerely interested in peace bolsters his strength at home.
Here’s a much more likely scenario than the Norks abandoning their nuke program: NK will cheat and Trump won’t stand for it. It will begin with a blockade. Hopefully that will lead to an NK economic collapse and not too many SKs will get hurt.
