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.The United States policy for dealing with a nuclear North Korea has been a combination of containment, deterrence, and limited engagement since the enactment of the 1994 Agreed Framework.

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.The question is if current U.S. policy has prevented North Korea from developing a nuclear program and exporting its technology to other countries. The answer is no. Even though one of North Korea's demands is to be removed from the list of state sponsored of terrorism, the North has not complied by following policies that would lead to that removal. Gregory J. Moore states that "the United States did not prevent North Korea from acquiring and testing nuclear weapons, despite its deterrent strategies, its diplomatic efforts, its ultimatums, and U.S.-sponsored UN Security Council resolutions against it." There are signs that the North should comply with the non-proliferation treaty. Gregory L. Schulte writes that, "Since the first atomic bomb was assembled, 18 countries have chosen to dismantle their nuclear weapons programs. Countries such as Argentina, Libya, South Africa, and Switzerland made this decision for a variety reasons, but foremost among them was the desire to improve their international standing. Another important factor was foreign pressure, especially from the United States." However, since the 1994 Agreed Framework, North Korea has not complied with any agreements they have made. Hence, the six-party talks are an example of failed American diplomacy.
