World System

International Relations Science has been developed to find an answer to the order puz-zle. The most important subject of processing theories of this field of study is providing an order paradigm between actors of the international system area. This paper aims at determining theories of international relations pertaining to order issue in the post-cold war international system. It seems that the field of international relations is confronted with too many paradigms for an explanation of its subject (order) because of the evolu-tion of its functional framework i.e. international system. Therefore, in reply to reasons of disorders and order issues, some important strategies like balance-driven order, insti-tution-based order, idea-based order, and justice-based order are presented, all of which are described. By the end, it has been tried to present appropriate paradigm indices of order in the current international system.

While other major global players emphasize the tangible characteristics of power, this alliance focuses on intangible power structures. For this purpose, this union is the only powerful normative identity player in the world community. Analysis of the position of this union in this context and its role in the fight against terrorism is the primary goal of the present article. Now, the main question is, what effect does the European Union's identity positioning have on this union's role in the fight against terrorism in the world system? According to the findings of the research, the European Union, be-sides enjoying normative identity advantages, as an essential international actor seeks an independent role in the fight against terrorism, but the lack of growth of standard military and security power in line with the development of normative power faces this union with a challenge and continues to rely on NATO under the leadership of the United States. The surge of terrorist activities in the territorial sphere of the European Union, the perceptual and psychological environment of the strategic and security policy-makers of the European Union on how to deal with terrorism, the specific attitude of right-wing European statesmen towards trends of terrorism, and the lack of social integration of Middle Eastern Muslim immigrants in European norms have led to more alignment and coherence of the European Union's strategic and security policies against terrorist movements.
