Catastrophic Collapse of North Korea (1996) http://bit.ly/1MAPxS1Beyond the Nuclear Crisis: A Strategy for the Korean Peninsula (2004) http://bit.ly/1CWA5vmShould The United States Support Korean Unification And If So, How? (2014) http://bit.ly/1IcFMGh
And this 2006 Atlantic article by Robert Kaplan: When North Korea Falls http://theatln.tc/1FgQvxj (He interviews Robert Collins and gives an overview of the Seven Phases of Collapse which is the seminal work on understanding how the regime might collapse and the indications and warnings that will give us an idea of failure of the regime)
The good news is that this collapse has the potential to be a win-win for nearly everyone. The North Korean people will end their terrible suffering, North and South Korea will be reunified under South Korean law, potentially following a UN-administered transitional period and referendum, the specter of a rogue nuclear nation at the heart of Asia will be removed, and China will gain a valuable trading partner in a unified Korea and access to Seoul’s high tech economy and northern Korea’s natural resources through high quality rail, road, and communications links. American troops could even be maintained below the 38th parallel to ease China’s fears of encirclement, with the long-term international relations of a unified Korea being up to the Korean people.North Korea is a historical relic, destabilizing force, and human rights abomination. The Korean people and the world will be far better off without it.
