Is peace an aberration? The New York Times bestselling author of Paris 1919 offers a provocative view of war as an essential component of humanity. NAMED ONE OF THE TEN BEST BOOKS OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW “Margaret MacMillan has produced another seminal work. . . . She is right that we must, more than ever, think about war. And she has shown us how in this brilliant, elegantly written book.”—H.R. McMaster, author of Dereliction of Duty and Battlegrounds: The Fight to Defend the Free World The instinct to fight may be innate in human nature, but war—organized violence—comes with organized society. War has shaped humanity’s history, its social and political institutions, its values and ideas. Our very language, our public spaces, our private memories, and some of our greatest cultural treasures reflect the glory and the misery of war. War is an uncomfortable and challenging subject not least because it brings out both the vilest and the noblest aspects of humanity. Margaret MacMillan looks at the ways in which war has influenced human society and how, in turn, changes in political organization, technology, or ideologies have affected how and why we fight. War: How Conflict Shaped Us explores such much-debated and controversial questions as: When did war first start? Does human nature doom us to fight one another? Why has war been described as the most organized of all human activities? Why are warriors almost always men? Is war ever within our control? Drawing on lessons from wars throughout the past, from classical history to the present day, MacMillan reveals the many faces of war—the way it has determined our past, our future, our views of the world, and our very conception of ourselves.

War has traditionally been studied as a problem deriving from the relations between states. Strategic doctrines, arms control agreements, and the foundation of international organizations such as the United Nations are designed to prevent wars between states. Since 1945, however, the incidence of interstate war has actually been declining rapidly, while the incidence of internal wars has been increasing. The author argues that in order to understand this significant change in historical patterns, we should jettison many of the analytical devices derived from international relations studies and shift attention to the problems of 'weak' states, those states unable to sustain domestic legitimacy and peace. This book surveys some of the foundations of state legitimacy and demonstrates why many weak states will be the locales of war in the future. Finally, the author asks what the United Nations can do about the problems of weak and failed states.

A detailed and highly authoritative critical commentary appraising the vitally important United States Department of Defense Law of War Manual.

In consideration of UN Resolution 1325 (which called for women's equal participation in promoting peace and security and for greater efforts to protect women exposed to violence during and after conflict), this volume takes stock of the current state of knowledge on women, peace and security issues, including efforts to increase women's participation in post-conflict reconstruction strategies and their protection from wartime sexual violence.

This collection focuses on non-kinetic warfare, including cyber, media, and economic warfare, as well as non-violent resistance, 'lawfare', and hostage-taking.

War is a fact of human nature. As long as we exist, it exists. That's how the argument goes. But longtime Scientific American writer John Horgan disagrees. Applying the scientific method to war leads Horgan to a radical conclusion: biologically speaking, we are just as likely to be peaceful as violent. War is not preordained, and furthermore, it should be thought of as a solvable, scientific problem—like curing cancer. But war and cancer differ in at least one crucial way: whereas cancer is a stubborn aspect of nature, war is our creation. It’s our choice whether to unmake it or not. In this compact, methodical treatise, Horgan examines dozens of examples and counterexamples—discussing chimpanzees and bonobos, warring and peaceful indigenous people, the World War I and Vietnam, Margaret Mead and General Sherman—as he finds his way to war’s complicated origins. Horgan argues for a far-reaching paradigm shift with profound implications for policy students, ethicists, military men and women, teachers, philosophers, or really, any engaged citizen.
