"North Korea poses two distinct but interrelated challenges. The first is external: the challenge posed by its nuclear weapons program and the threat of proliferation off the Korean Peninsula. The second is essentially but not wholly internal: the challenge posed by the pending transfer of power in Pyongyang and potential for instability as the process plays out. This complex reality underscores the need for balance and strategic patience if the twin dangers of proliferation and instability on the peninsula are to be successfully managed. U.S. national security interests on the Korean Peninsula are focused on deterrence of North Korea, defense of the Republic of Korea (ROK) if deterrence should fail, and support for Korean unification under the ROK. The United States also has a national security interest in North Korea's stability. This interest should not be mistaken as support for the Pyongyang regime, but given the risks posed by its nuclear weapons program, instability could result in the loss of command and control over those weapons and increase the risk of proliferation. The Six-Party Talks aimed at the denuclearization of North Korea are currently suspended. Nevertheless, diplomacy with North Korea will likely resume at some point but be protracted in nature. The policy challenge is what to do while the diplomacy plays out. The United States, the ROK, and Japan are acting correctly by maintaining close and effective policy coordination. The goal of U.S. diplomacy remains denuclearization. This will take time, and our security strategy must deal with the world as it is. The commitment of the administration of President Barack Obama to extended deterrence is critical in supporting both U.S. diplomatic and security strategy and its allies."--Page 1.
