Iran and the “six” of international negotiators reached an agreement in July 2015 to resolve the long-standing problem of the Iranian atom. The months-long negotiations culminated in the adoption of a joint comprehensive action plan (JCPOA), the implementation of which will completely remove Iran’s previously imposed economic and financial sanctions by the UN Security Council, the United States and the European Union. The agreement also provided that the arms embargo will be lifted from Iran within five years, arms deliveries are possible earlier, but only with the permission of the UN Security Council. The deal in its original form did not survive even three years: in May 2018, the United States announced a unilateral exit from it and the restoration of severe sanctions against Tehran. Nevertheless, since only the United States formally withdrew from the deal, the rest of its participants must abide by the condition of lifting the arms embargo.
