Today, the question of Palestine is one of the most urgent and significant topics in the study of  world politics and international relations. Despite the United Nations' efforts for over seven decades to establish peace, security in this case, the goal seems to be more elusive than before. In this context, it is relevant to mention the right of veto power in the United Nations Security Council. The use of veto power in this body, whose main goal is to maintain peace, has often prevented the adoption of resolutions that could contribute to addressing the question of Palestine, hindering progress towards a peaceful solution. The purpose of this essay is thus to examine how the US, with its veto power in the UNSC , has influenced the role of the UN in the question of Palestine. The research issue is examined through the lens of realism and hegemony. To carry out this research, a qualitative content analysis has been employed as the methodology. The results indicate that the UN's inability to address the question of Palestine is due to the power and support of the US towards Israel. The US uses its veto power to protect Israel from criticism in the UNSC. This dynamic has played a role in preventing a solution to the question of Palestine and has made it difficult for the UN to act as a neutral mediator in this conflict. The UN's lack of effectiveness in this issue calls into question its status as a dependable international actor.
