For decades, the United States has led the effort to stem the spread of nuclear weapons, both among potential adversaries and among its allies and partners. The current state of deterrence and of the nonproliferation regime, however, is open to many doubts. What happens if the nonproliferation regime should break down altogether? What happens if extended deterrence should fail, and allies no longer believe in the credibility of the U.S. nuclear umbrella? What happens when the world has not 9 but 11, 15, 18, or even more nuclear powers? This study explores how such a world might function and what it would mean for our present conceptions of deterrence, for the place of the United States in the international order, and for international order itself.
Project Atom is a forward-looking, “blue-sky” review of U.S. nuclear strategy and posture in a 2025-2050 world in which nuclear weapons are still necessary. The report highlights and addresses the current deficit in national security attention paid to the continued relevance and importance of U.S. nuclear strategy and force posture, provides a new open-source baseline for understanding the nuclear strategies of other countries, and offers a credible, intellectually tested, and nonpartisan range of options for the United States to consider in revising its own nuclear strategy.
In policy pronouncements over the last two administrations, the protection of the American homeland was regularly identified as the first priority of U.S. missile defense efforts. Homeland missile defense today is provided by the Ground-based Midcourse Defense program and other elements of the larger Ballistic Missile Defense System. The limited defenses fielded today have advanced considerably since limited defensive operations began in late 2004, but nevertheless they remain too limited and too modest relative to emerging threats. The Missile Defense Agency’s path to improve the system may require additional effort to stay ahead of even limited missile threats. This report explains how the current system works, as well as current and potential plans to modernize the system, and the authors offer recommendations for future evolution of the system.
Despite the rising salience of missile threats, current air and missile defense forces are far too susceptible to suppression. Today’s U.S. air and missile defense (AMD) force lacks the depth, capacity, and operational flexibility to simultaneously perform both missions. Discussions about improving AMD usually revolve around improvements to the capability and capacity of interceptors or sensors. Rather than simply doing more of the same, the joint integrated air and missile defense (IAMD) efforts might be well served by new or reinvigorated operational concepts, here discussed collectively as “Distributed Defense.” By leveraging networked integration, Distributed Defense envisions a more flexible and more dispersible air and missile defense force capable of imposing costs and dilemmas on an adversary, complicating the suppression of U.S. air and missile defenses. Although capability and capacity improvements remain essential to the high-end threats, the Distributed Defense concept focuses on creating a new architecture for today’s fielded or soon-to-be fielded IAMD force to boost flexibility and resilience.
This study explores the growing competition for scarce dollars at the U.S. Missile Defense Agency (MDA). It traces the authorities, roles, and missions assigned to the agency and the growing trend of using what was originally intended to be a research and development budget for procurement and sustainment of missile defense assets. As adversary missile arsenals develop in both size and sophistication, continued improvements to our current missile defense systems will be required to keep pace with the threat. The combination of an ever shrinking top line and new roles and missions being assigned to MDA make that task difficult. Finding a new path forward and more clearly defining the position of the agency inside the Department of Defense will be essential for a more sustainable missile defense posture.
In scientific computing (also known as computational science), advanced computing capabilities are used to solve complex problems. This self-contained book describes and analyzes reported software failures related to the major topics within scientific computing: mathematical modeling of phenomena; numerical analysis (number representation, rounding, conditioning); mathematical aspects and complexity of algorithms, systems, or software; concurrent computing (parallelization, scheduling, synchronization); and numerical data (such as input of data and design of control logic). Readers will find lists of related, interesting bugs, MATLAB examples, and ?excursions? that provide necessary background, as well as an in-depth analysis of various aspects of the selected bugs. Illustrative examples of numerical principles such as machine numbers, rounding errors, condition numbers, and complexity are also included. ?
This text engages students with the ethical decisions faced by health care professionals every day. Based on principles and applications in health care ethics and the law, this text extends beyond areas that are often included in discussions of political philosophy and the principles of justice.
Haitian Creole (HC) is spoken by approximately 11,000,000 persons in Haiti and in diaspora communities in the United States and throughout the Caribbean. Thus, it is of great utility to Anglophone professionals engaged in various activities—medical, social, educational, welfare— in these regions. As the most widely spoken and best described creole language, a knowledge of its vocabulary is of interest and utility to scholars in a variety of disciplines. The English-Haitian Creole Bilingual Dictionary (EHCBD) aims to assist anglophone users in constructing written and oral discourse in HC; it also will aid HC speakers to translate from English to their language. As the most elaborate and extensive linguistic tool available, it contains about 30 000 individual entries, many of which have multiple senses and include subentries, multiword phrases or idioms. The distinguishing feature of the EHCBD is the inclusion of translated sentence-length illustrative examples that provide important information on usage.
An original study of empire creation and its consequences, from ancient through early modern times The world’s first great empires established by the ancient Persians, Chinese, and Romans are well known, but not the empires that emerged on their margins in response to them over the course of 2,500 years. These counterempires or shadow empires, which changed the course of history, include the imperial nomad confederacies that arose in Mongolia and extorted resources from China rather than attempting to conquer it, as well as maritime empires such as ancient Athens that controlled trade without seeking territorial hegemony. In Shadow Empires, Thomas Barfield identifies seven kinds of counterempire and explores their rise, politics, economics, and longevity. What all these counterempires had in common was their interactions with existing empires that created the conditions for their development. When highly successful, these counterempires left the shadows to become the world’s largest empires—for example, those of the medieval Muslim Arabs and of the Mongol heirs of Chinggis Khan. Three former shadow empires—Manchu Qing China, Tsarist Russia, and British India—made this transformation in the late eighteenth century and came to rule most of Eurasia. However, the DNA of their origins endured in their unique ruling strategies. Indeed, world powers still use these strategies today, long after their roots in shadow empires have been forgotten. Looking afresh at the histories of important types of empires that are often ignored, Shadow Empires provides an original account of empire formation from the ancient world to the early modern period.
For the monumental Poetry Competition in Six Hundred Rounds (Roppyakuban uta’awase), twelve poets each provided one hundred waka poems, fifty on seasonal topics and fifty on love, which were matched, critiqued by the participants and judged by Fujiwara no Shunzei, the premiere poet of his age. Its critical importance is heightened by the addition of a lengthy Appeal (chinjō) against Shunzei’s judgements by the conservative poet and monk, Kenshō. It is one of the key texts for understanding poetic and critical practice in late twelfth century Japan, and of the conflict between conservative and innovative poets. The Competition and Appeal are presented here for the first time in complete English translation with accompanying commentary and explanatory notes by Thomas McAuley.
