The Legality of Israel's Use of Armed Force In Disputes With Palestine Reviewed From Article 51 Of The UN Charter on Self-Defense

The conflict between Harakat al-Muqawamah al-Islamiyyah (HAMAS) and Israel, which peaked on October 7, 2023, has given rise to the dynamics of international legal issues, especially related to international humanitarian law and human rights law. Based on this conflict, the principle of self-defense has become a debate among the international community regarding compliance with the provisions of the UN Charter. In the Charter of the United Nations (UN), the concept of the exercise of the right of self-defense as stipulated in Article 51 of the UN Charter is the basis and justification for Israel to use armed force against the Hamas Group in Palestine. The research method of this writing uses a juridical-normative approach with a statute approach. This approach is used to examine and analyze the legal provisions governing self-defense, especially against the conflict between Hamas and Israel in Palestine. The author will review Israel's actions in carrying out counterattacks against Hamas in Palestine by analyzing elements of Article 51 of the UN Charter, as well as on the basis of cases that have occurred, both resolved through the International Court of Justice and those that have been stopped due to bilateral agreements
