North Korea jams foreign radio and television signals. It is a criminal offence to read, listen to or watch non sanctioned media. North Koreans are among the most propagandized/abused populations on the planet. They do not have a clue as to what is going on.
Allowing the regime to continue unchecked is to allow their abysmal human rights abuses to continue. Negotiating with the regime facilitates the abuse.
Extreme, draconian sanctions is the lesser of all evils. If China does not take him out hopefully a patriot in his inner circle will set aside his fear of torture and do the world a favor.
