This agreement is arguably the most important and the most complex of this century. It treats with widespread concerns about Iran’s nuclear program. It resolves a serious nonproliferation problem for at least 15 years and likely beyond. It sets U.S.-Iranian relations on a new course. It opens the door of possible change in the Middle East region while at the same time also raising issues for key U.S. relationships there. The agreement between Iran and the P-5 + 1 (Five Permanent Members of the U.N. Security Council—China, France, Russia, the United Kingdom, and the United States, plus Germany) was concluded after many years of negotiation on July 14, 2015.
This article describes the agreement, explores the arguments against it, and summarizes the views of experts on how to evaluate it. The agreement is 159 pages, technically complex as it deals with key elements of nuclear science related to civil nuclear uses and weapons. It is accompanied by a U.N. Security Council (UNSC) resolution and is before the U.S. Congress until about Sept. 20, 2015. It has been and will continue to be the subject of debate, politics, and emotion. This guide is provided to be helpful in understanding its key elements and importance—politics and emotion are left to the individual reader.
