The United States policy for dealing with a nuclear North Korea has been a combination of containment, deterrence, and limited engagement since 1994. While this policy has prevented war on the Korean peninsula, it has not prevented North Korea from developing a nuclear program and proliferating this technology, as well as missile technology, to numerous countries not friendly to the United States. In order to stop North Korea from transferring weapons technology, the United States needs a new strategic concept. This paper will examine four options that may be used to support the element of the U.S. National Security Strategy of preventing the proliferation of nuclear weapons.
