(JCPoA) Comprehensive Joint Plan of Action and its Role in Non-Proliferation in International Law

Weapons of mass destruction and their destructive effects have always been the focus of lawyers' efforts to create legal barriers to non-proliferation, as the consequences of these weapons are far from universal in the international community. This article, while addressing the nature of the international agreement of the Joint Comprehensive Plan of Action, which is called the "JCPOA", (as is called "Barjam" in Persian) seeks to examine the role of non-proliferation of WMDs in international law. In this paper, after expanding the conceptual space of the "JCPOA ", its importance and role in the non-proliferation of WMDs are discussed. The research method used in this article is descriptive-analytical and data collection has been done in the form of libraries. The findings of this study suggest that JCPOA, through its commitment to and implementation of the International Atomic Energy Agency's Additional Protocol and Safeguards, and the memoranda and transparency measures set out in the text of the Vienna Agreement, reduce international arms competition and non-proliferation. The ruling affects the non-proliferation of weapons of mass destruction.
