The U.S.-Japan alliance has been hailed as the “cornerstone” of peace in the Pacific. The alliance relationship has been strengthened and institutionalized over the years. However, there is a considerable gap between the two countries in their understandings of concepts such as use of force and the right of collective self-defense. This is problematic: the continuation of the gap may lead to wrong expectations at both diplomatic and operational levels and weaken the alliance in the future.
This workshop is an attempt to bring together experts from the United States and Japan to discuss how the two countries can address this gap and seek ways in which the two countries can utilize international law as the common language of diplomacy. With experts from fields of international law and political science, we will discuss conceptual issues as well as specific regional concerns and new domains such as cyberspace and outer space.
