Ask HN: What can we do (individuals and community) to stop war with North Korea?

I'd like to see Trump and Kim meet in neutral territory, in person, and form a personal relationship.

I'd also like to see all the rich entrepreneurs in the tech community stand tall and use their money to prevent war.

Everyone stands to lose a great deal if this madness is not cooled down.

I can't think of a war since WW2 that anyone won.... including the U.S.

What else can be done?
