An Explanation of the Break and Theoretical Transformation from Classical Terrorism to Modern Terrorism

As an inevitable phenomenon, terrorism has directly and indirectly engaged the formal and informal actors of the international system, and has gradually expanded the geographical scope of terrorist acts. This research is intended to assess the capability of the theories of international politics to respond to the conceptual transformation of terrorism, and to try to provide an answer to this question: “What are the most important features of the theoretical transformation of classical terrorism to modern terrorism?” With this in mind, due to the fact that theories in the field of international politics have not been able to analyze modern terrorism well, we tried to test the hypothesis that, there is a theoretical rupture in the concept of modern terrorism compared to the classical type following the process of globalization and change in the system International on the basis of systemic and multilevel views. Accordingly, the most important components of the theoretical transformation and of classical terrorism compared to modern terrorism are: increase of threats, generalization and expansion, change in the nature and function, importance of organizational, networking and cyber terrorism, geographical spread of international terrorism and change in activists' reaction to international terrorism. This is a theoretical research following explanatory method whose data are collected on the basis of library and internet resources.
