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.

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.
