Purpose: This article recognizes the dangers of North Korea's continued hostilities, including the sinking of the Cheonan, shelling of Yeonpyeong Island, and missile launches, and raises awareness in order for the forces threat-ening national security not to be established in our society. The goal is to have a firm military readiness so that we can fully respond to North Korea's provocations at any time and in any form. Method: In order to analyze North Korea's intentions and threats of provocation toward South Korea, books, academic journals, and dissertations about the provocation toward South Korea were reviewed. Various daily newspapers, news, and government data were studied to recognize the importance of security and derive em-pirical data for establishing military readiness. Results: North Korea has carried out military provocations against South Korea in various forms over the past 70 years despite our efforts to improve relations with the North. Until North Korea gives up its hostile policy toward South Korea and takes tangible military measures, it is the main enemy that threatens our security. We must make a clear distinction between the enemy and the ally. In addition, economic aid to North Korea should be continued while strengthening its nuclear deterrence and inducing change in the North. There should be no war, but it should be prepared to respond immediately if there is. Conclusion: National security is directly related to the survival of the people and is not done by the order of someone. It is important to have the same idea about security, from the leaders of the country, including the president, to all the people. We should keep in mind that national development stems from the people's thorough sense of security and have a security perspective that we protect our country. We should realize the importance of national security and have a firm military preparedness.
