What is The supreme organ of the United nation?

The supreme organ of the United Nations is the General Assembly. It comprises all 193 member states, each having one vote, and serves as a forum for discussion on international issues, including peace and security, development, and human rights. The General Assembly meets annually and plays a crucial role in setting the UN's agenda and budget, although its resolutions are generally non-binding. Decisions on key issues, such as peace and security, require a two-thirds majority, while other matters are decided by a simple majority.
