The making of policy for nuclear security requires a strong grasp of the associated technical matters. That grasp came naturally in the early decades of the nuclear era, when scientists and engineers were deeply engaged in policymaking. In more recent decades, the technical community has played a narrower role, one generally limited to implementing policies made by others. This narrower role has been accentuated by generational change in the technical community, as the scientists and engineers who conceived, built, and executed the programs that created the existing U.S. nuclear deterrent faded into history along with the long-term competition for technical improvements with the Soviet Union. There is thus today a clear need to impart to the new generation of nuclear policy experts the necessary technical context.That is the purpose of this paper. Specifically: to introduce a new generation of nuclear policy experts to the technical perspectives of a nuclear weapon designer, to explain the science and engineering of nuclear weapons for the policy generalist, to review the evolution of the U.S. approach to nuclear weapons design, to explain the main attributes of the existing U.S. nuclear stockpile, to explain the functions of the nuclear weapons complex, and how this all is integrated to sustain deterrence into the future.

For decades, nuclear deterrence has been at the heart of the transatlantic relationship between the United States and Europe. It underpins European security, and the North Atlantic Treaty Organization (NATO) continuously commits to remaining a nuclear alliance as long as nuclear weapons exist. And yet, with a few important exceptions, transatlantic dialogue on nuclear issues largely declined with the end of the Cold War, particularly among non-governmental experts--and has only started to be revived in recent years. Rebuilding deterrence dialogue in response to a shifting strategic landscape is an important step in strengthening not only the transatlantic partnership, but also European security. This paper collection explores the evolving deterrence dialogue in Europe and identifies ways to inject new momentum into that dialogue. Renewed attention on the issue is particularly timely as European actors confront an adventurist Russia, rising China, and new technologies that will impact nuclear deterrence, U.S.-Europe relations, and institutions such as the Nuclear Non-Proliferation Treaty.

This book examines the recent shift in US space policy and the forces that continually draw the US back into a space-technology security dilemma. The dual-use nature of the vast majority of space technology, meaning of value to both civilian and military communities and being unable to differentiate offensive from defensive intent of military hardware, makes space an area particularly ripe for a security dilemma. In contrast to previous administrations, the Obama Administration has pursued a less militaristic space policy, instead employing a strategic restraint approach that stressed multilateral diplomacy to space challenges. The latter required international solutions and the United States, subsequently, even voiced support for an International Code of Conduct for Space. That policy held until the Chinese anti-satellite (ASAT) test in 2013, which demonstrated expanded Chinese capabilities. This volume explores the issues arising from evolving space capabilities across the world and the security challenges this poses. It subsequently discusses the complexity of the space environment and argues that all tools of national power must be used, with some degree of balance, toward addressing space challenges and achieving space goals. This book will be of much interest to students of space policy, defence studies, foreign policy, security studies and IR.

From a brilliant Brookings Institution expert, an “important” (The Wall Street Journal) and “penetrating historical and political study” (Nature) of the critical role that oceans play in the daily struggle for global power, in the bestselling tradition of Robert Kaplan’s The Revenge of Geography. For centuries, oceans were the chessboard on which empires battled for supremacy. But in the nuclear age, air power and missile systems dominated our worries about security, and for the United States, the economy was largely driven by domestic production, with trucking and railways that crisscrossed the continent serving as the primary modes of commercial transit. All that has changed, as nine-tenths of global commerce and the bulk of energy trade is today linked to sea-based flows. A brightly painted forty-foot steel shipping container loaded in Asia with twenty tons of goods may arrive literally anywhere else in the world; how that really happens and who actually profits from it show that the struggle for power on the seas is a critical issue today. Now, in vivid, closely observed prose, Bruce Jones conducts us on a fascinating voyage through the great modern ports and naval bases—from the vast container ports of Hong Kong and Shanghai to the vital naval base of the American Seventh Fleet in Hawaii to the sophisticated security arrangements in the Port of New York. Along the way, the book illustrates how global commerce works, that we are amidst a global naval arms race, and why the oceans are so crucial to America’s standing going forward. As Jones reveals, the three great geopolitical struggles of our time—for military power, for economic dominance, and over our changing climate—are playing out atop, within, and below the world’s oceans. The essential question, he shows, is this: who will rule the waves and set the terms of the world to come?

"Artificial intelligence (AI) and big data promise to help reshape the global order. For decades, most political observers believed that liberal democracy offered the only plausible future pathways for big, industrially sophisticated countries to make their citizens rich. Now, by allowing governments to monitor, understand, and control their citizens far more effectively than ever before, AI offers a plausible way for big, economically advanced countries to make their citizens rich while maintaining control over them--the first since the end of the Cold War. That may help fuel and shape renewed international competition between types of political regimes that are all becoming more "digital." Just as competition between liberal democratic, fascist, and communist social systems defined much of the twentieth century, how may the struggle between digital liberal democracy and digital authoritarianism define and shape the twenty-first? This work highlights several key areas where AI-related technologies have clear implications for globally integrated strategic planning and requirements development"--
