If the regime of North Korean Supreme Leader Kim Jong Un was to collapse, whether from internal problems or external force, one of the most pressing problems facing the United States, China, and South Korea—as well as one of the most promising avenues for cooperation—would be how to respond to the resulting humanitarian crisis, according to Joonbum Bae and Andrew Natsios.
