I think the regime in North Korea is more fragile than people think. The country's economic system remains desperate, and one thing that could happen for example would be under a new government in South Korea, to get the South Korean government to live up to its own constitution, which says any Korean who makes it to South Korea, is a Korean citizen. A citizen of the Republic of Korea. And you could imagine the impact that would have inside North Korea if people thought, "If I could get out and make it to South Korea, I could have a different life."
