According to the text, the pursuit of unification should focus on functional and tangible unification through economic cooperation and the dismantling and integration process. The future strategy should include overcoming national division and achieving peace and co-prosperity on the Korean peninsula. However, the unification process is also influenced by international factors and requires cooperation from neighboring countries. In order to successfully prepare for unification, discussions on unification and peace need to take place. It should also be noted that unification without a specific agreement between South and North Korea is difficult. Finally, the issue of national division and unification is not only a domestic issue but also an international issue, as it has been impacted by neighboring countries and has a dual nature.
