Structure, powers and needs of UN reform

The United Nations (UN) is the foundation of modern international legal architecture, having been created in 1945 in response to the tragedy of World War II and the failure of the league of Nations. Its role is to ensure international peace and security, promote human rights, international cooperation and harmonious global development. The UN brings together 193 member states, making it the largest existing multilateral institutional framework. The UN Charter, adopted in San Francisco, remains the" Constitution of the international community, " providing the legal basis for all its powers. In essence, the emergence of the UN was a turning point in the evolution of international law, since for the first time states consented to create an organization with its own international legal personality, endowed with the ability to act and adopt decisions with global impact. The UN Charter enshrined the principle of collective security - a joint commitment of states to respond in solidarity to threats to peace-replacing the bilateral or regional system of the interwar period, marked by fragility and inefficiency. At the same time, the UN has become an indispensable forum for multilateral diplomacy, where states can express their interests, negotiate compromises and adopt legal instruments with universal applicability. Today, the UN functions as a complex network of specialized institutions, mechanisms and agencies designed to manage global problems of unprecedented diversity: armed conflict, international terrorism, climate change, migration, pandemics, unequal economic development, Food Crises, Energy Security, accelerated digitization or artificial intelligence. The UN system reflects, more than any other international structure, the interdependence of the contemporary world, in which regional events have immediate consequences for the entire international community.
