Political-legal assessment of US unilateral economic sanctions against the Islamic Republic of Iran

In this article we have tried to study the different aspects of bilateral relations and the role of sanctions in these relations. In answer to the main question- what is the role and place of US unilateral sanctions against I.R.Iran in terms of international law; we have attempted to address the role of pressures on the I.R.Iran through unilateral US sanctions, using the theory of "offensive realism". The results suggest that: The United States and the European Union have used cooperative mechanisms in the world system to unilaterally impose sanctions on Iran, creating the conditions for a change in Iran's behavioral patterns to transition from UN Security Council sanctions and sanctions. Forced diplomacy is seen as part of US strategic reality to persuade and limit the Islamic Republic's strategic power. From the point of view of international law, although many of these tools have been used in pursuit of unilateral interests and hegemonic policies contrary to human rights law, sanctions policy is viewed as a countermeasure as well as a collective action by the United Nations Charter. The Security Council has relative legitimacy and, consequently, good performance.
