The United Nations (UN) has seen a significant decline in its influence and relevance in global diplomacy since the end of the Cold War. Initially founded in 1945 to prevent wars, the UN now struggles with a membership of 193 states, many of which are aligned with superpowers like the US, Russia, and China. The article highlights the diminishing respect for the UN, particularly in the context of conflicts in Iran, Ukraine, and North Korea, where leaders such as Donald Trump, Vladimir Putin, and Xi Jinping prefer unilateral action over multilateral cooperation. Thant Myint-U, a biographer of former UN Secretary-General U Thant, calls for a revival of the UN's moral authority and multilateral institutions, emphasizing the importance of diplomacy over military action. The piece argues that while the UN may not regain its former power, it can still serve as a platform for humanitarian efforts and peacekeeping if global leaders prioritize traditional diplomacy. The article concludes that restoring respect for professional diplomats and the UN's humanitarian mission is crucial for a more stable international landscape.
