"Trump Administration statements, including President Trump's speech to the U.N. General Assembly on September 19, 2017, indicate that the Administration does not believe that the 2015 multilateral nuclear agreement with Iran, the Joint Comprehensive Plan of Action (JCPOA), addresses the full range of potential threats posed by Iran. Administration officials assert that the Administration is considering ending or altering U.S. implementation of the JCPOA - a decision that is opposed by the other powers that negotiated the accord with Iran: Russia, China, France, Britain, and Germany. This report analyzes some of the options the Administration might use to end or alter U.S. implementation of the JCPOA, if there is a decision to do so. These options, which might involve use of procedures in the JCPOA itself or the Iran Nuclear Agreement Review Act (P.L. 114-17), are not necessarily mutually exclusive. Some potential implications of Administration decisions on the JCPOA are analyzed as well."
