The world has always witnessed the rise and fall of great powers and the significance of the study of power shifts is due to their relevance to war, peace and security of international system. According to Charles Doran and Dylan Kissane’s Power Cycles theory, the role of a country is enhanced parallel with its power enhancement, otherwise it may lead to unpleasant upheavals in international arena. On the other hand, the balance between power and role would lead to international peace and stability. In this paper, the main question is how would the ranking of great powers be changed by 2025 and what political- security implications would it have for Iran? The analysis will focus on the US, China, India and Russia. China has become a great power with her economic takeoff. Yet the US will continue to remain superior among the superpowers thanks to its military power and political willingness. China will assist Iran to secure her economic power and enable it to mitigate the US pressures by 2025. The methodology employed in this article is analytic- comparative in which the predictions are based on statistical methods and time series. Here, the library and Internet resources as well as related statistical analysis software (Minitab &SPSS) have been used as research tools.
