I think this is exactly what we would do, but not the way you probably think. Think forward observes directing bombs/missiles using GPS/LD etc. We need to make sure we get him with photographic/video evidence if possible, and we are not going to be able to get too close without being detected (closed society). Need to make sure he is in the open, in well lit area and you have sufficient line of sight to remain far enough away to not be detected, and not be killed by blast or fragments. Send in a SEAL team, send target cords or lase for indirect fires (air delivered most likely) and videotape event. Team gets extracted and the world sees lil Kim dead. The chemical weapons stuff doesn’t make sense to me— it would be possible if they were trying to take him alive, but that would be completely insane from a risk perspective.
Air is direct fire.
I really don't want to see him dead, but to live so that he and others can learn how "dead wrong" he was about the two Koreas being unified under the flag of freedom.
