The ball is in China's court. It is their responsibility to reign in NK and its murderous, nuclear threatening dictator. China has been allowed to use NK as a proxy in its battle for top dog country with the US, it must stop and no one should back down because of China's appeal to level heads--we are beyond that;  it is time for China to act decisively in its direct sphere and move beyond starving the people of NK to suffocating the murderous psychopath that leads it.
