Comparing to the divided sovereignty issue, after ending of Cold War, North Korean nuclear crisis has brought the new threat to Korea Peninsula and regional security. However, what noteworthy to mention about is, though North Korea seems like being the core of this crisis, and regarded as the trouble-maker that the Six-Party Talks built together by China, US, Japan, Russia, South Korea and North Korea in 2003 try to suppress induce, the fact that continuous procrastination of a final act still implies that, maybe the strategic confrontation among major powers is the real show for this crisis. Accordingly, in this paper, this author will try to explain how North Korea crisis would influence the Northeast Asia power structure, and what might happen in the near future.
