The main goal of the United Nations (UN) is to promote international cooperation and maintain world peace and security. Established in 1945 after World War II, the UN aims to prevent conflicts, provide humanitarian aid, and uphold human rights worldwide. It addresses global challenges such as climate change, poverty, health crises, and inequality through various specialized agencies and programs. The organization serves as a forum for dialogue among member states, fostering collaboration toward sustainable development and collective solutions to pressing global issues.
