With the dramatically changed balance of power, historical issues continuing to color contemporary international relations, North Korea's nuclear and missile development seemingly unresolvable, and both the United States and Russia "pivoting" toward the region, East Asia today is a region in flux. This course will provide a review of the developments of major power relations and challenges facing political and security policy communities in the region. The course will include a scenario building exercise guided by competing theories of international relations. There are no prerequisites for this course.
