The "damage limitation" that the United States envisioned against the Soviet Union at the beginning of the Cold War between the United States and the Soviet Union is resurfacing today. This is because nuclear nations emphasize the attitude of controlling the power of nuclear weapons to prove that they are practical means of use. The U.S. officially mentioned damage limits in the 2018 Nuclear Posture Review (NPR). In the event of a failure to deterrence, the United States will minimize the damage it will inflict as much as possible in view of the actual nuclear war situation. Meanwhile, North Korea's nuclear capabilities continue to sophisticate. Domestic and foreign experts assessed that North Korea's possession of nuclear warheads is constantly increasing, and that there is a great possibility of combining nuclear warheads with short-range missiles. Under these circumstances, South Korea needs to make efforts to reduce the damage it will receive from a nuclear attack by North Korea after the failure of deterrence. However, since damage limitation is a measure that assumes war, the problem of impeding crisis stability must be considered at the same time. Therefore, this article examines the possibility of limiting damage based on South Korea's conventional forces under the growing threat of nuclear war, and at the same time discusses the vulnerabilities it will cause. This emphasizes the need for a balanced "damage limitation strategy" for South Korea.
