The main function of the United Nations in global politics is to promote international cooperation and maintain peace and security among nations. Established in 1945, the UN serves as a platform for dialogue and conflict resolution, offering forums for discussions on various issues—from humanitarian aid to sustainable development. Notably, the UN works to uphold human rights and fosters international law through various treaties and conventions. Its peacekeeping missions and diplomatic efforts aim to prevent conflict escalation and provide support to nations in turmoil, playing an essential role in promoting global stability.
