Every new decision on foreign policy along with withdrawal announcement by Trump’s administration astonishes the world. This process could be described by the term “Unforeseeable” due to its unconventionality. Therefore, this paper aim is to root out the fundamental cause. Then the main question is what are the leading factors in the U.S foreign policy under Trump administration? In response to the point of view, by using the theory of “continuity” and the findings of two personality-characterization studies, assessing foreign policy positions, analyzing how he interacts with foreign policy institutions and its internal developments, it is argued as a hypothesis that psychological traits of Trump has promoted the status of individual factor on other influential resources of American foreign policy, namely, systemic, bureaucratic, social and role factors. “Populist Authoritarianism”, “Narcissism”, "Revengefulness" and” disagreeableness” are the most prominent characteristics of Trump’s personality which lead U.S toward an Egoistic foreign policy. These individual characteristics of Trump outweighs the bureaucratic institutions of foreign policy, hence made the institutions completely in line with the views of the president. Challenging accompanied by withdrawing from international treaties and arrangements can be considered as result; To the extent that, according to some experts, the existing world order and its compounds are at stake.
