The end of World War II shaped the path for the Korean Peninsula and remains near the top of the U.S. foreign policy agenda, with the Republic of Korea (ROC) as a close ally and the Democratic People's Republic of Korea (DPRK) as a consistent pain in the butt. The assumption is that sooner or later the North will fall and we will see reunification as we have seen in nation-states such as Germany and Vietnam.
The Atlantic Council has a good piece, The Cost of Korean Reunification, that I want to recommend. There will be significant challenges to reunification, the largest likely being the economic costs involved in combing a highly successful economy with one that has major starvation issues.
