Terrorism: Commentary on Security Documents is a series that provides primary source documents and expert commentary on the worldwide counter-terrorism effort. Among the documents collected are transcripts of Congressional testimony, reports by such federal government bodies as the Congressional Research Service (CRS) and the Government Accountability Office (GAO), and case law covering issues related to terrorism. Each volume carries a single theme, and inside each volume the documents appear within topic-based categories. The series also includes a subject index and other indices that guide the user through this complex area of the law. Volume 121, Nuclear Non-Proliferation Treaty, covers recent developments relating to the 2010 NPT Review Conference, primarily those pertaining to Iran and North Korea. After the 2005 Review Conference ended without a final consensus declaration due to disputes over Iran's nuclear activities, Israel's nuclear program, and implementation of the Middle East nuclear weapon-free zone, the lack of consensus in 2005 combined with continued concern over the nuclear programs of Iran and North Korea made the 2010 Review Conference a critical moment in the achievement of the NPT's goals. Kristen Boon provides introductory analysis of the key documents relating to the NPT generally and the 2010 NPT Review Conference in particular. The documents in this volume include the Final Declaration of the 2000 Conference, statements made by the key parties at the 2010 Conference, the Final Statement of the 2010 Conference, and related UN Security Council resolutions from 2009 and 2010. Professor Boon also includes renewed discussion of two critical past documents, the U.S. Nuclear Posture Review Report of April 6, 2010, and the U.S. National Security Strategy of May 27, 2010.
