This paper explores the illegal Israeli occupation of Palestinian territories, focusing on the West Bank and Gaza after 1967. It employs a qualitative research approach, analyzing primary and secondary sources to examine the legal ramifications of Israel’s ongoing occupation and settlement expansion, which violate international law. The findings highlight that, despite various international resolutions, Israel continues its unlawful presence. Key legal rulings, such as the International Court of Justice’s decision of July 19, 2024 and a UN General Assembly resolution in September 2024, reaffirm the illegality of Israel’s actions. Nonetheless, Israel has ignored these calls for withdrawal and persists in expanding settlements. The paper argues that the UN member states must enforce international legal rulings and hold Israel accountable through international courts. It advocates for the imposition of economic and diplomatic sanctions by the UN Security Council to curb settlement expansion and dismantle existing illegal settlements, emphasizing the need for coordinated international efforts to achieve justice for Palestine.
