    YCAPS and The Sasakawa Peace Foundation are excited to announce our next event in Sasebo. This event will feature Dr. Takuya Matsuda, who will lead us in a discussion on the trilateral security relations between the United States of America (U.S.), Japan and South Korea and address the future of the U.S. alliance system in East Asia.


    The emerging great power competition in the western Pacific has prompted gradual qualitative changes to the alliance structure in the region. Alliances are increasingly being regarded as a means to create military power. Japan, for example, has been upgrading its security strategies in order to strengthen the U.S.-Japan alliance. Moreover, the growing U.S.-Japan-South Korea trilateral security relationship as underscored in the Camp David Summit in mid-August illuminates these major changes in the way alliances are operationalized in the region. By examining this trilateral security relationship, this seminar will explore the evolving nature of the U.S. alliance system in East Asia as well as its implications for the region and beyond.


    All are welcome and free food and refreshments will be provided.
