The intelligence failures exposed by the events of 9/11 and the missing weapons of mass destruction in Iraq have made one thing perfectly clear: change is needed in how the U.S. intelligence community operates. "Transforming U.S. Intelligence" argues that transforming intelligence requires as much a look to the future as to the past and a focus more on the art and practice of intelligence rather than on its bureaucratic arrangements. In fact, while the recent restructuring, including the creation of the Department of Homeland Security, may solve some problems, it has also created new ones. The authors of this volume agree that transforming policies and practices will be the most effective way to tackle future challenges facing the nation's security. This volume's contributors, who have served in intelligence agencies, the Departments of State or Defense, and the staffs of congressional oversight committees, bring their experience as insiders to bear in thoughtful and thought-provoking essays that address what such an overhaul of the system will require. In the first section, contributors discuss twenty-first-century security challenges and how the intelligence community can successfully defend U.S. national interests. The second section focuses on new technologies and modified policies that can increase the effectiveness of intelligence gathering and analysis. Finally, contributors consider management procedures that ensure the implementation of enhanced capabilities in practice. "Transforming U.S. Intelligence" supports the mandate of the new director of national intelligence by offering both careful analysis of existing strengths and weaknesses in U.S. intelligence and specific recommendations on how to fix its problems without harming its strengths. These recommendations, based on intimate knowledge of the way U.S. intelligence actually works, include suggestions for the creative mixing of technologies with new missions to bring about the transformation of U.S. intelligence without incurring unnecessary harm or expense. The goal is the creation of an intelligence community that can rapidly respond to developments in international politics, such as the emergence of nimble terrorist networks while reconciling national security requirements with the rights and liberties of American citizens.

A history of winning intelligence practices from the Spanish Armada to Cyberwar that offers timeless, practical lessons we ignore at our peril. According to conventional wisdom, strategic surprise and other intelligence failures are both inevitable and ultimately irrelevant because, at least in international politics and war, military muscle matters more than brains. In Decision Advantage, Jennifer E. Sims counters this argument by investigating the history of intelligence through centuries of international conflict, including the 16th Century's Spanish Armada, two US Civil War battles, the hunt for President Lincoln's assassin, and key diplomatic crises before the two World Wars. Sims dives deep into these events to show that the competitive pursuit of intelligence advantage has been a measurable, buildable, and consequential form of power that can help competitors win against otherwise stronger opponents. From these observations, the author develops a general guide to building intelligence readiness, whether for war, diplomacy, or international manhunts. Refuting arguments that intelligence is a sideshow because intentions are unknowable and predictions risky, she redefines success as gaining information advantages over an adversary, prescribes four practical pathways for gaining them, and confirms what seems to be simple common sense: smart competitors know how to learn, and the ones who learn best tend to win. Thinking of intelligence in this way, Sims argues, adds a moral character to an enterprise that is too often mired in excessive secrecy and tyrannical agendas. By "lifting the veil" on international politics, Decision Advantage shows how good intelligence can lessen the likelihood of wars of misperception and folly.

Decision makers matching wits with an adversary want intelligence -- good, relevant information to help them win. Intelligence can gain these advantages through directed research and analysis, agile collection, and the timely use of guile and theft. Counterintelligence is the art and practice of defeating these endeavors. Its purpose is the same as that of positive intelligence -- to gain advantage -- but it does so by exploiting, disrupting, denying, or manipulating the intelligence activities of others. The tools of counterintelligence include security systems, deception, and disguise: vaults, mirrors, and masks.

In one indispensable volume, top practitioners and scholars in the field explain the importance of counterintelligence today and explore the causes of -- and practical solutions for -- U.S. counterintelligence weaknesses. These experts stress the importance of developing a sound strategic vision in order to improve U.S. counterintelligence and emphasize the challenges posed by technological change, confused purposes, political culture, and bureaucratic rigidity. "Vaults, Mirrors, and Masks" skillfully reveals that robust counterintelligence is vital to ensuring America's security.
