The aim of this paper is to illuminate some aspects of the Jeju 4.3 Grand Tragedy (the Jeju Tragedy) education and informing process. We hope to not only with these aspects show some aspects of moral origin of the Jeju World Peace Island movement, but to share a culture of peace with world citizens through world civilization education cross the Pacific at a local, national and global level. In addition bring liberty to the cause of national freedom of the SAM IL movement of 1919 in Korea. it actualizes itself as a peace buffer zone locally, nationally and globally through the “Jeju World Peace Island Treaty JWPIT,” based on international agreement of the Six Talks Nations because “it is believed that that they (Jeju islanders) will follow the pattern of the SAM IL movement of 1919 with the participants imbued with the spirit of sacrifice to life and liberty to the cause of national freedom (G-2 Summary Report)” as a moral origin of Jeju World Peace Island. Globally, one New Haven teacher has been working on an elective course called “The Power of Culture in a Multicultural World” in which to use social studies tools to investigate the meaning and importance of culture. Jeju offers an excellent opportunity to explore a culture that few New Haven students are familiar with. It will be for students to use the Jeju idea of turning troubles into opportunities, as a vehicle for addressing local issues” (“New Haven Learn- Teach Jeju 4.3,” New Haven Independent: March 29, 2017). Another New Haven teacher in his history class explains the different components of genocide. “Although the Jeju 4.3 events are not deemed genocide by the international community, using this as a lens to understand broader concepts seemed really exciting.” Jeju offers educators an opportunity to teach the curriculum but instead of gratuitous death and violence, there is a legacy of hope, healing, reconciliation and remembrance.” (Ibid, New Haven Independent: March 29, 2017). Locally and partially on the global level, “The Resurgence of Jeju 4.3 Social Healing Advocacy of “PETITION FOR A JOINT SOUTH KOREA AND UNITED STATES JEJU 4.3 INCIDENT TASK FORCE TO FURTHER IMPLEMENT RECOMMENDATIONS AND FOSTER COMPREHENSIVE AND ENDURING SOCIAL HEALING THROUGH JUSTICE” (March 27, 2014). The petition supports a combined solution to social healing for numerous survivors of Jeju 4.3. Based on interviews with members of the Jeju 4.3 Victim Family Association, 20% of them are now elderly and require expensive medical care and assistance. Many continue to suffer from psychological trauma (PTSD). It serves as a beacon of international peace in the same vein as May 24, 2015’s event, “Women Cross DMZ Demilitarized Zone.” Jeju itself aims to serve as a “Peace Buffer Zone” between the two Koreas among 6 Nations Talks within the framework of the Jeju World Peace Island Treaty, similar to Costa Rica. Never before has the need for a Peace Island in the region been so vital, with China stretching its reach across the ocean, and President Trump flexing his muscles against North Korea, the time has come for serious peacemaking, that is, prevention of conflict. It’s a real time to think about actualization of Jeju World Peace Island Treaty for Peace between two Koreas.
