For the last half century, as administrations have come and gone, the fundamental assumptions about America's military policy have remained unchanged: American security requires the United States (and us alone) to maintain a permanent armed presence around the globe, to prepare our forces for military operations in far-flung regions, and to be ready to intervene anywhere at any time. In the Obama era, just as in the Bush years, these beliefs remain unquestioned gospel.

When we think about the future of war, the military and Washington and most everyone gets it backwards. We think in terms of buying single military systems, such as fighter jets or aircraft carriers. And when we think about modernizing those systems, we think about buying better versions of the same things. But what really matters is not the single system but "the battle network"—the collection of sensors and shooters that enables a military to find an enemy system, target it, and attack it.

Henry Kissinger offers in World Order a deep meditation on the roots of international harmony and global disorder. Drawing on his experience as one of the foremost statesmen of the modern era Kissinger now reveals his analysis of the ultimate challenge for the 21st century: How to build a shared international order in a world of divergent historical perspectives, violent conflict, proliferating technology, and ideological extremism.

Kilcullen brings together his most salient writings on this vitally important topic. Here is a picture of modern warfare by someone who has had his boots on the ground in some of today's worst trouble spots - including Iraq and Afghanistan - and who has been studying counterinsurgency since 1985. Filled with down-to-earth, common-sense insights, this book is the definitive account of counterinsurgency, indispensable for all those interested in making sense of our world in an age of terror.

In Strategy: A History, Sir Lawrence Freedman, one of the world's leading authorities on war and international politics, captures the vast history of strategic thinking, in a consistently engaging and insightful account of how strategy came to pervade every aspect of our lives.

This book explores the dramatic difference between the Russian and US approach to warfare, which manifests itself across the whole spectrum of activities from art and the economy to the respective national cultures; illustrates the fact that Russian economic, military, and cultural realities and power are no longer what American "elites" think they are by addressing Russia's new and elevated capacities in the areas of traditional warfare, as well as cyberwarfare and space; and studies several ways in-depth in which the US can simply stumble into conflict with Russia and what must be done to avoid it.

In Team of Teams, retired four-star General Stanley McChrystal and former Navy SEAL Chris Fussell made the case for a new organizational model combining the agility, adaptability, and cohesion of a small team with the power and resources of a giant organization. Now, in One Mission, Fussell channels all his experiences, both military and corporate, into powerful strategies for unifying isolated and distrustful teams.

From the end of World War II until 1980, virtually no American soldiers were killed in action while serving in the Greater Middle East. Since 1990, virtually no American soldiers have been killed in action anywhere else. What caused this shift? Andrew J. Bacevich, one of the country's most respected voices on foreign affairs, offers an incisive critical history of this ongoing military enterprise - now more than 30 years old and with no end in sight.

Refuge seeks to restore moral purpose and clarity to refugee policy. Rather than assuming indefinite dependency, Collier - author of The Bottom Billion - and his Oxford colleague Betts propose a humanitarian approach integrated with a new economic agenda that begins with jobs, restores autonomy, and rebuilds people's ability to help themselves and their societies.

A decade after the cold war ended, policy makers and academics foresaw a new era of peace and prosperity, an era in which democracy and open trade would herald the "end of history." The terrorist attacks of September 11, 2001, sadly shattered these idyllic illusions, and John Mearsheimer's masterful new book explains why these harmonious visions remain utopian.

This book analyzes the evolution of Russian military thought and how Russia's current thinking about war is reflected in recent crises. What Jonsson reveals is that Russia's conception of the very nature of war is now changing, as Russian elites see information warfare and political subversion as the most important ways to conduct contemporary war. Since information warfare and political subversion are below the traditional threshold of armed violence, this has blurred the boundaries between war and peace.

One need not look hard to see how the incredible advances in artificial intelligence, cryptocurrencies, biotechnologies, and the Internet of things are transforming society in unprecedented ways. But the fourth industrial revolution is just beginning, says Schwab. And at a time of such tremendous uncertainty and such rapid change, he argues it's our actions as individuals and leaders that will determine the trajectory our future will take.

When Americans think of modern warfare, what comes to mind is the US army skirmishing with terrorists and insurgents in the mountains of Afghanistan. But the face of global conflict is ever-changing. In Out of the Mountains, David Kilcullen, one of the world's leading experts on current and future conflict, offers a groundbreaking look at what may happen after today's wars end.

An examination of a world increasingly defined by disorder and a United States unable to shape the world in its image, from the president of the Council on Foreign Relations. Things fall apart; the center cannot hold. The rules, policies, and institutions that have guided the world since World War II have largely run their course. Respect for sovereignty alone cannot uphold order in an age defined by global challenges from terrorism and the spread of nuclear weapons to climate change and cyberspace. Meanwhile, great power rivalry is returning.

Red teaming. It is a practice as old as the Devil's Advocate, the 11th-century Vatican official charged with discrediting candidates for sainthood. Today, red teams - comprised primarily of fearless skeptics and those assuming the role of saboteurs who seek to better understand the interests, intentions, and capabilities of institutions or potential competitors - are used widely in both the public and private sector.
