The N. Koreans have a history of being provocative when they are in trouble internally. Usually it has to do with crop failure or something similar. It seems that asking for help makes them and their system seem to be failures, which of course they are. But if they act out then we will meet with them and offer them something they can’t refuse. They will agree to our offer and they save face.
I’m sure the intelligence agencies know what they want already and in a short time they will agree to stop firing missiles and we will send a boatload of rice or medicine or something.
This has been going on for decades. While their leader (or figurehead) might be a goofball or more likely incapacitated, the military knows that aggression against China, S. Korea or Japan would be the end of their regime.
