Sadly there's no good way to resolve this conflict that does not end in death and greater suffering. Even if the Kim family dynasty finally collaspes under sanctions, you are potentially looking mass chaos and an internal power stuggle, which coud also lead to many deaths. I know I would like to see this conflict resolved, if necessary by force, but let us not forgot how easy it can be to idealize war. If it comes to conflict, all sides will feel tremendous loss both economically and in human life.
