The United Nations, founded in 1945, is a prominent international organization dedicated to maintaining peace, security, human rights and promoting socio-economic development. Comprised of key organs including the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice and the Secretariat, the UN also relies on specialized agencies such as WHO, UNESCO and FAO to address specific global issues. Despite notable achievements, there is an urgent need for reform, particularly within the Security Council, to better align the organization with contemporary challenges and improve its effectiveness. This reform specifically implies the restructuring of the Security Council. Only through comprehensive changes can the UN develop into a more responsive and effective entity capable of addressing current and future global issues.
