The Goldwater-Nichols Department of Defense Reorganization Act of 1986 is the most important legislation to affecting U.S. national defense in the last 50 years. This act resulted from frustration in Congress and among certain military officers concerning what they believed to be the poor quality of military advice available to civilian decision-makers. It also derived from the U.S. military's perceived inability to conduct successful joint or multi-service operations. The act, passes after four years of legislative debate, designated the Chairman of the Joint Chiefs of Staff as the principal military advisor to the President and sought to foster greater cooperation among the military services. Goldwater-Nichols marks the latest attempt to balance competing tendencies within the Department of Defense, namely centralization versus decentralization and geographic versus functional distributions of power. As a result of the Goldwater-Nichols Act, the Chairman of the Joint Chiefs has achieved prominence, but his assignment is somewhat contradictory: the spokesman and thus the advocate for the Commander in Chief, while simultaneously the provider of objective advice to the President. While the act did succeed in strengthening the CINCs' authority and in contributing to the dramatic U.S. achievements in the Gulf War, the air and ground campaigns revealed weaknesses in the CINCs' capability to plan joint operations. In addition, the increased role of the military in ad hoc peacekeeping operations has challenged the U.S. military's current organizational structure for the quick deployment of troops from the various services. Rapid technological advances and post-Cold War strategic uncertainty also complicate the U.S. military's organizational structure.

Preface 2012 edition: The United States Code is the official codification of the general and permanent laws of the United States. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First session, enacted between January 3, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 USC 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office. -- John. A. Boehner, Speaker of the House of Representatives, Washington, D.C., January 15, 2013--Page VII.
