This report provides background information on the negotiations over North Korea's nuclear weapons program that began in the early 1990s under the Clinton Administration. As US policy toward Pyongyang evolved through the George W. Bush presidency and into the Obama Administration, the negotiations moved from mostly bilateral to the multilateral Six-Party Talks. Although the negotiations have reached some key agreements, major problems with the implementation have persisted. With talks suspended since 2009, concern about proliferation to other actors has grown.

As U.S. policy toward Pyongyang evolved through the George W. Bush presidency and into the Obama Administration, the negotiations moved from mostly bilateral to the multilateral Six-Party Talks (made up of China, Japan, Russia, North Korea, South Korea, and the United States).

This report describes President Trump's current policy toward North Korea and possible options for future U.S. policy.

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.

Although the primary focus of U.S. policy toward North Korea is the nuclear weapons program, there are a host of other issues, which this report explores through an overview of the U.S.-North Korea relationship, including an emphasis on the diplomacy of the Six-Party Talks. Please refer to the list at the end of this report for the full list of CRS reports focusing on other North Korean issues.

This report discusses how as North Korea has accelerated its missile and nuclear programs in spite of international sanctions, Congress and the Trump Administration have elevated North Korea to a top U.S. foreign policy priority. Legislation such as the North Korea Sanctions and Policy Enhancement Act of 2016 (P.L. 114-122) and international sanctions imposed by the United Nations Security Council have focused on North Korea's WMD and ballistic missile programs and human rights abuses. North Korea's cyberattacks have the potential not only to disrupt international commerce, but to direct resources to its clandestine weapons and delivery system programs, potentially enhancing its ability to evade international sanctions. This report will provide a brief summary of what unclassified open-source reporting has revealed about the secretive program, introduce four case studies in which North Korean operators are suspected of having perpetrated malicious operations, and provide an overview of the international finance messaging service that these hackers may be exploiting.

This report discusses the recent comments and upcoming summits between North Korea, South Korea, and the United States regarding denuclearization and negotiating a formal peace treaty to officially end the Korean War. A brief overview of past attempts to negotiate a peace treaty between the parties in the Korean War is provided and current priorities for a peace treaty are provided.

This report discusses the rapid advancements North Korea has made in its nuclear weapons and ballistic missile programs since 2012. Despite the absence of any missile launch activity or nuclear tests in 2018 to date, previous tests and official North Korean statements suggest that North Korea is striving to build a credible regional nuclear warfighting capability that might evade regional ballistic missile defenses. Such an approach likely reinforces their deterrent and coercive diplomacy strategy--lending more credibility as it demonstrates capability--but it also raises serious questions about crisis stability and escalation control. Congress may further examine these advances' possible effects on U.S. policy.

Much of the debate over U.S. policy toward Iran has centered on the nature of the current regime; some believe that Iran, a country of about 70 million people, is a threat to U.S. interests because hardliners in Iran's regime dominate and set a policy direction intended to challenge U.S. influence and allies in the region. President George W. Bush, in his January 29, 2002, State of the Union message, labeled Iran part of an "axis of evil" along with Iraq and North Korea.
