Purpose: The purpose of this paper is to think about the benefits and gains which unification will bring about in our reality as divided nations, understand the legitimacy for unification, and devised a strategy for preparing for unification. The purpose is to establish values and a desirable attitude towards the state while preparing for unification and analyzing the stature and future of the Republic of Korea. Method: In order to come up with the legitimacy of unification, strategy, and what we need to do to prepare for unification, references such as books, academic journals, and dissertations related to unification were examined, and in order to derive empirical data for the stature of South Korea and the future, empirical studies were conducted for news and government data, etc. Results: The strategy to prepare for unification is to induce North Korea not to make unreasonable demands by maintaining a strong security arrangement, such as by securing regular and irregular warfare capabilities, strengthening the ROK-U.S. alliance and joint operational capabilities, and adhering to firm principles rather than a principle of less appeasement policy not to mislead the public s perception of North Korea. Unification requires an agreement between the two Koreas, yet what is clear is that unification must be liberal and democratic based on a market economy, and it is also necessary to reach a national consensus. Furthermore, while expanding the breadth of mutual understanding between the two Koreas, close friendly and cooperative relations with neighboring countries must also be maintained. Conclusion: Most of the people have a negative perception towards unification, and the MZ generation even demonstrate a cynical attitude towards North Korea. However, unification must be achieved in order to pursue development and prosperity while continuing the historical legitimacy of our people, and for stability in Northeast Asia and the world peace. In the process of pursuing unification, it should serve as an opportunity to properly establish the ‘view of state’ as well as the ‘view of unification’ or ‘view of security’ which have not been fully established in the consciousness of the people.
