The United Nations (UN) was established in 1945 to maintain international peace and security, yet its crisis managementcapacity has been increasingly questioned in the twenty-first century. This article examines the ineffectiveness of the UN inresponding to contemporary conflicts, focusing on two critical cases: the ongoing war in Ukraine (2022–Present) and theGaza conflict (2023– Present). Both crises highlight the structural limitations of the UN Security Council (UNSC), particularlythe veto power held by its permanent members (P5), which often paralyzes decision-making where great-power interestsare directly involved.The study employs a comparative case study method, drawing upon primary sources such as UN resolutions, SecurityCouncil debates, and General Assembly voting records, as well as secondary academic analyses and policy reports. Thetheoretical framework integrates realism, which emphasizes power politics and state interests; liberal institutionalism,which underscores multilateralism and the institutional role of the UN; and constructivism, which highlights the importanceof norms, legitimacy, and international perceptions.Findings indicate that in Ukraine, Russia’s veto has shielded it from binding UNSC measures, relegating the UN to a primarilyhumanitarian role with limited political influence. In Gaza, repeated U.S. vetoes have prevented collective action againstIsrael, despite mounting humanitarian crises and allegations of international humanitarian law violations. In both cases, theUN General Assembly has attempted to fill the vacuum through symbolic resolutions, yet these measures lack bindingauthority.The analysis concludes that the UN remains a normative platform capable of articulating principles of international law andmorality but lacks enforcement capacity to manage crises when great powers are implicated. The article argues forsubstantive institutional reforms, including Security Council restructuring, limitations on the veto in cases of mass atrocities,and hybrid mechanisms linking global and regional organizations to enhance legitimacy and effectiveness in crisismanagement.
