Assuring South Korea and Japan as the Role and Number of U.S. Nuclear Weapons are Reduced   [open pdf - 426KB]

"Japan and the Republic of Korea (ROK) are among the principal allies of the United States and perhaps its most important allies in the Asia-Pacific region. The two are key democratic, trading, diplomatic, and military partners of the United States. Both countries have defense ties with United States that are nearly six decades old. The security arrangements with each country include a nuclear guarantee by which the United States pledges its readiness to use nuclear forces to protect its ally. The nuclear guarantee to each ally serves two distinct, but related, purposes: to discourage an attack against the ally (extended deterrence) and to give the ally confidence in the U.S. commitment to its defense (assurance). Ongoing developments in Northeast Asia have caused both Tokyo and Seoul to raise questions about U.S. nuclear commitments. These developments are the growth in Chinese military power and Beijing's efforts to exert greater influence in the region, and the new nuclear capabilities of North Korea and Pyongyang's provocative behavior. In addition, the nuclear weapon policies of the United States have been a source of allied concern. [...] The need to assure allies of U.S. security commitments, including nuclear guarantees, as the United States seeks lower numbers of nuclear weapons and a smaller nuclear role, is an imperative recognized by the NPR [Nuclear Posture Review] and in subsequent statements by U.S. officials. Changes in the Northeast Asian security environment and changes in U.S. nuclear weapons policies thus present the problem of assuring Japan and South Korea as further nuclear reductions are pursued."
