At the 78th UN General Assembly Session in New York, the Indonesian Minister of Foreign Affairs expressed Indonesia's concern about the condition of the Palestinian people in the Israeli-Palestinian conflict. This speech also emphasized that Indonesia would not stop providing support for the Palestinian people to gain independence. During the conflict, both parties have violated human rights, namely the right to live in safety and other rights. This phenomenon is in stark contrast to the foundation of the Indonesian state, Pancasila, as a national ideology, aspires to justice and prosperity for every individual. In the 1945 Constitution, Indonesia stated that it rejected colonialism and was ready to participate in world order. This commitment is proven by Indonesia's diplomatic activities for world peace. The free and active political system and the Non-Aligned Movement practiced by Indonesia really support Indonesia to become a neutral mediator in regional and international conflicts. This article examines the implementation of Pancasila in world peace, especially in efforts to mediate the Israeli-Palestinian conflict.
