This report describes President Trump's current policy toward North Korea and possible options for future U.S. policy. Options include diplomatic engagement, international and U.S. sanction increases, military strikes, destabilization of the North Korean government through intelligence activities and popular resentment, enhanced military cooperation with allies, and additional funding for preventing arms trading and related trade with North Korea.

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 U.S. policy toward Pyongyang evolved through the George W. Bush and Obama presidencies, 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).

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.

This report discusses the economic sanctions the United States imposes on North Korea for activities related to weapons proliferation, destabilizing the region, anti-terrorism, and undemocratic governance.

This report provides background information on the deployment of nuclear weapon systems in South Korea in the past, explores the options that might be available for the redeployment of nuclear weapons to South Korea now to deter the North Korean threat, and discusses the potential implications of doing so for South Korea, North Korea, Japan, and the U.S.
