A System in Need of Renewal: The United Nations and the Challenges to the Liberal International Order

This paper explores the evolution, practical achievements, and contemporary systemic crises of the United Nations (UN) within the context of the liberal international order. Established in 1945 following the failure of the League of Nations, the UN was designed as the central pillar of post-war multilateralism, collective security, and global governance. The study reviews the UN's historical origins, highlighting its key operational successes in peacekeeping, humanitarian assistance, and standard-setting for human rights. However, the analysis demonstrates how mid-twentieth-century institutional frameworks, particularly the structure and veto power of the UN Security Council, have created severe paralysis in addressing modern geopolitical threats. Examining contemporary case studies in Syria Gaza and Ukraine, the paper illustrates how power politics and structural gridlock undermine the UN’s core principles of international law and territorial integrity. The paper concludes that to safeguard the liberal international political order and restore its leverage for global stability, the United Nations requires comprehensive structural transformation adapted to twenty-first-century realities.
