The United Nations plays a critical role in international politics by promoting global peace, security, and cooperation among nations. It serves as a forum for states to discuss and resolve conflicts, primarily through diplomatic negotiations and dialogues. The UN also coordinates humanitarian efforts, addresses global challenges like climate change, and advances human rights initiatives. Through its various agencies and peacekeeping missions, the UN works to prevent conflicts and support sustainable development worldwide. Its importance lies in fostering multilateral collaboration and maintaining a rules-based international order.
