Given the modern achievements, analysis of new developments in the international arena require putting aside the traditional understanding and enjoying instead a knowledge of influential forces that are effective on dynamism, trends and results as well as introduction of new concepts. In this way, the current paper reviews developments of the US foreign policy in the last two decades and the related theories about allocation of capabilities that are effective in shaping the poles of an international system; it also argues that, like in the past, in order to better understand the developments, it would be better to get to know the structure of poles in the international system; however, this is not enough and to achieve better understanding, one needs to know all influential new forces that affect dynamism, trends and results. To do so, the paper offers the idea of trans-pole concept according to which power is not bound to the old inter-governmental, limited and inflexible situation but enjoys some new aspects.
