At any time in history, various countries take a reflection at their policies and see if they are out of touch or are on track with their behaviors over a particular period of time (Duedney, Daniel, &Jeffrey, 2008, p, 2). According to Rosenau, Smith, & Smith, (209, p,38, & p, 42) what actually consist of his work on foreign policy analysis in the 960s and early 970s the trend of his work is far less easy to determine. Rosenau goes on to claim that, his second volume can offer much light on interdependence and transnationalism which is clearly concerned with the phenomenon of international relations, and in no area, is this more visible than in foreign policy analysis. Foreign Policies had often been described as interplay between various political agents and structures formed by social structures. Also, foreign policies are the determinants in how a country conducts itself. Usually, when the topic of Foreign policies comes up the next topic on the top of most peoples mind is diplomatic ties, countries are always in competition with each other be it business o
r social structures. One must understand one thing, when it comes to talking about a countries foreign policies it all comes down to how they interacts with other nations. Moreover, when considering countries foreign policies it has always been important to pick out what is very essential because, there are quite numerous factors involved when taking particular countries into consideration. The paper attempts to show the crucial factors that matter in the processes that shape them when considering these countries: Iran, United States of America and China. Before, going into details when considering the factors internally they depicts the inputs to the foreign policy making processes as the external, societal, governmental role and individual categories that make up the analytical framework whereas the external source category refers to the attributes of the international system and to the characteristics and behaviors. Foreign policy has to do with relations with other countries so what makes China, Iran and USA so unique and dominant in spheres of influence.
