This study was analyzed from the perspective of the 2nd generation of Jeju 4·3 experienced residents, unrelated to the ideology of right or left. This study was approached from the perspective of a historical trauma. In order to confirm the cause of this traumatic event, collective stigma politically imposed on Jeju at macro system were analyzed and four Korean national daily newspapers titled Donga Ilbo(1962-1999), Kyung Hyang Newspaper (1947-1999), Maeil Business Newspaper (1966-1999), Hankyoreh Newspaper (1989-1999) were analyzed by the key word Jeju 4·3 in the Naver news library at exo system[1]. And interview results were analyzed at micro system. Incurring the “unidentified unsafe feeling”, anxiety and fear that even innocent ordinary people from Jeju Island could be stigmatized in “red” without their knowledge whether they were left or right, different attitudes changing at various systems have had influence on trauma transmission from generation to generation since 1948 until now. This research showed that the sense of safety or security at all the level of systems was never secured over 70 years. Therefore, publicly guaranteed safety feeling at macro system should become the starting line of recovering the Jeju 4·3 historical trauma. The Jeju 4·3 related historical trauma, which has been handed down through generations in the silence of 70 years, should be solved by the central government policy.
