The text discusses the importance of pursuing functional and substantial unification between North and South Korea through economic cooperation and a future strategy of unification, rather than viewing it solely as a political and territorial concept. The author emphasizes the need for a unified Korea to navigate through the complex international environment and secure its future. However, the current political landscape, as well as issues such as inequality, insecurity, and lack of concrete agreement on unification, make it challenging to achieve. Furthermore, with North Korea's continued development of nuclear and missile capabilities, the tensions on the Korean peninsula continue to rise. The text suggests that open communication and dialogue between the North and South will be crucial for the future of the peninsula.
