This report presents background information and discusses potential issues for Congress relating to U.S. ballistic missile defense (BMD) efforts in the Asia-Pacific region. These efforts pose several potential policy, funding, and oversight issues for Congress. Decisions that Congress makes on these issues could affect U.S. defense funding requirements and military capabilities, and U.S. relations with countries in the Asia Pacific region, including China, Japan, South Korea, North Korea, and Australia.
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.
