Examining Change in the Structure of the International System: Based on a Modified Structure from the Waltz Model

Investigating the possibility of change in the structures of the international system by modifications in the Waltz model of the structure is the main goal of this research. The main question is how to make Waltz's model capable of explaining the structural change in the system. In order to answer this question, the concepts and variables affecting the international outcomes are identified by evaluation and doing a review of Waltz theory and the critics and commentators to offer the proposed plan of this research while being loyal to the Waltz model for a better understanding of the change of structures in the international system. Our results show the stillness of Waltz's model to changes in the structures of the international system, especially in the ordering principles and functional specification. Also, the results show that the Waltz model needs modification due to the lack of the structure of the process. We define a tolerance within two extremes for ordering principle in the first element of the political structure of the system and units, then we change the direction from the principle of difference and similarity to the principle of differentiation and separation in the second element of the political structure of the system and units and finally, we add a third structure called the structure of the process. The triple structure of the international system is presented as the solution of this research to explain the structural change and the emergence of alternative systems.
