North Korea has presented one of the most vexing and persistent problems in U.S. foreign policy in the post-Cold War period. The United States has never had formal diplomatic relations with the Democratic People's Republic of Korea (the official name for North Korea), although contact at a lower level has ebbed and flowed over the years. Negotiations over North Korea's nuclear weapons program have occupied the past three U.S. administrations, even as some analysts anticipated a collapse of the isolated authoritarian regime. North Korea has been the recipient of over $1 billion in U.S. aid (though none since 2009) and the target of dozens of U.S. sanctions. This report covers the overall U.S.-North Korea relationship, with an emphasis on nuclear diplomacy.

This report summarizes what is known from open sources about the North Korean nuclear weapons program--including weapons-usable fissile material and warhead estimates--and assesses current developments in achieving denuclearization.

At least 50 documented incidents in more than 20 countries around the world, many involving arrest or detention of North Korean diplomats, link North Korea to drug trafficking. Such events, in the context of credible, but unproven, allegations of large scale state sponsorship of drug production and trafficking, raise important issues for the United States and its allies in combating international drug trafficking. The challenge to policy makers is how to pursue an effective counter drug policy and comply with U.S. law which may require cutting off aid to North Korea while pursuing other high-priority U.S. foreign policy objectives including (1) limiting possession and production of weapons of mass destruction; (2) limiting ballistic missile production and export; (3) curbing terrorism, counterfeiting, and international crime; and (4) addressing humanitarian needs.
