The reasons of the US withdrawal from JCPOA based on the Neoclassical Realism Perspective

Joint Comprehensive Plan of Action (JCPOA) is one of the important legal and international events in the international relations history. This international agreement, result of two years formal and intensive negotiations, was signed between Iran and 5+1 countries, in Vienna. Following the signing of this document, the Security Council resolution 2231 legislated. According to this resolution, previous Security Council sanctions have been canceled and JCPOA signatory countries were forced to implement the commitments which were inserted on it. However, it did not take long time that the new president of America, Donald Trump, revealed his incompatibility with Iran's multilateral international nuclear agreement. Finally, the United States government officially gets out of the Joint Comprehensive Plan of Action. Therefore, this study tries to answer this question that, what are the reasons of the US withdrawal from the Joint Comprehensive Plan of Action? In order to answer this question this hypothesis examined that the US withdrawal of the Joint Comprehensive Plan of Action can be examined in individual level: Trump characteristics, national: unilateralism approach from the “First America” doctrine and systemic: supporting regional allies and consolidate America's hegemonic position. The research method in this study is descriptive-analytic and the method of data collection is library and internet. The use of neoclassical realism theory to examine the causes of America's exit of the Joint Comprehensive Plan of Action is the research innovation in the present study.
