Northeast Asia is the center of the world's most protracted, and unsuccessful, effort to roll back nuclear proliferation, and the story is far from over. North Korea has resisted diplomacy and endured isolation from the international community for decades and continues to build up its nuclear arsenal. The region is also home to two close allies of the United States : the Republic of Korea and Japan. Two great nuclear-armed states, Russia and China, are also in the region. Chapters 13 and 14 analyze this situation from the vantage points of both Japan and South Korea. Possibilities for easing tensions and moving away from nuclear confrontations are presented.
