From Rosana's point of view, following the decline of the dominant role of states in the international arena, the world system has changed from a uni-polar to a multi-polar system. In the new system, there are many independent players. In crease in citizen's knowldge and individual expertise is one of the charactristics of our new world. In this era, legitimacy is no longer derived from authority and other traditional values, but success and evaluation of achievments on the two levels of international and domestic affairs are the basis for legitimacy. Technological development, interchange of thoughts, and expansion of global communication, which are the result of the information revolution, have changed the principles of international relations. In the meantime, because of the decline in the traditional role of states, the U.N has found a new and more powerful role in international affairs, even presenting the criteria of legitimacy.
