No single individual or entity rules the entire world. The world is divided into sovereign nations, each with its own government and leaders. The international system is based on the principles of state sovereignty and non-interference in the internal affairs of other nations. The United Nations (UN) is an international organization that plays a significant role in promoting international cooperation, peace, and security. The UN consists of member states that work together on various global issues, but it does not have authority over the internal affairs of individual countries. Global governance is a complex system involving various international organizations, treaties, and agreements that address issues like trade, climate change, human rights, and more. No single entity or individual has ultimate authority or control over every aspect of the world. Instead, global governance involves cooperation, diplomacy, and negotiation among nations to address common challenges and shared interests.
