One of the most contentious issues in contemporary foreign policy—especially in the United States—is the use of military force to intervene in the domestic affairs of other states. Some military interventions explicitly try to transform the domestic institutions of the states they target; others do not, instead attempting only to reverse foreign policies or resolve disputes without trying to reshape the internal landscape of the target state. In Leaders at War, Elizabeth N. Saunders provides a framework for understanding when and why great powers seek to transform foreign institutions and societies through military interventions. She highlights a crucial but often-overlooked factor in international relations: the role of individual leaders. Saunders argues that leaders' threat perceptions—specifically, whether they believe that threats ultimately originate from the internal characteristics of other states—influence both the decision to intervene and the choice of intervention strategy. These perceptions affect the degree to which leaders use intervention to remake the domestic institutions of target states. Using archival and historical sources, Saunders concentrates on U.S. military interventions during the Cold War, focusing on the presidencies of Eisenhower, Kennedy, and Johnson. After demonstrating the importance of leaders in this period, she also explores the theory's applicability to other historical and contemporary settings including the post–Cold War period and the war in Iraq.

A comparison of nine leaders who led their nations through the greatest wars the world has ever seen and whose unique strengths—and weaknesses—shaped the course of human history, from the bestselling, award-winning author of Churchill, Napoleon, and The Last King of America “Has the enjoyable feel of a lively dinner table conversation with an opinionated guest.” —The New York Times Book Review Taking us from the French Revolution to the Cold War, Andrew Roberts presents a bracingly honest and deeply insightful look at nine major figures in modern history: Napoleon Bonaparte, Horatio Nelson, Winston Churchill, Adolf Hitler, Joseph Stalin, George C. Marshall, Charles de Gaulle, Dwight D. Eisenhower, and Margaret Thatcher. Each of these leaders fundamentally shaped the outcome of the war in which their nation was embroiled. Is war leadership unique, or did these leaders have something in common, traits and techniques that transcend time and place and can be applied to the essential nature of conflict? Meticulously researched and compellingly written, Leadership in War presents readers with fresh, complex portraits of leaders who approached war with different tactics and weapons, but with the common goal of success in the face of battle. Both inspiring and cautionary, these portraits offer important lessons on leadership in times of struggle, unease, and discord. With his trademark verve and incisive observation, Roberts reveals the qualities that doom even the most promising leaders to failure, as well as the traits that lead to victory.

Preventive war has a long history in international politics, but until it became an instrumental part of the Bush Doctrine, it was mostly overlooked. Renshon argues that the best avenue for understanding decisions to initiate preventive action is through a close examination of the individual leader responsible for such decisions. In this work, he develops a theory of psychological motivations for preventive action. By examining five situations, including the Iraq war, he pinpoints the factors that matter most in decisions to take preventive military action. There have been preventive wars throughout history, but the motivations behind them have remained elusive, and many crucial questions remain unanswered. What exactly constitutes preventive action? What differentiates preventive action from pre-emptive action? Are there significant differences between preventive strikes and full-on preventive wars? What is the relationship of preventive action to traditional concepts of deterrence, compellence, and international law? Finally, why do states initiate preventive action? Renshon argues that the best avenue for understanding decisions to initiate preventive action is through a close examination of the individual leader responsible for such decisions.

Using in-depth research on famous leaders, this book explores how their life experiences fundamentally shape the reasons why nations go to war.

NEW YORK TIMES BESTSELLER • From a preeminent presidential historian comes a “superb and important” (The New York Times Book Review) saga of America’s wartime chief executives “Fascinating and heartbreaking . . . timely . . . Beschloss’s broad scope lets you draw important crosscutting lessons about presidential leadership.”—Bill Gates Widely acclaimed and ten years in the making, Michael Beschloss’s Presidents of War is an intimate and irresistibly readable chronicle of the Chief Executives who took the United States into conflict and mobilized it for victory. From the War of 1812 to Vietnam, we see these leaders considering the difficult decision to send hundreds of thousands of Americans to their deaths; struggling with Congress, the courts, the press, and antiwar protesters; seeking comfort from their spouses and friends; and dropping to their knees in prayer. Through Beschloss’s interviews with surviving participants and findings in original letters and once-classified national security documents, we come to understand how these Presidents were able to withstand the pressures of war—or were broken by them. Presidents of War combines this sense of immediacy with the overarching context of two centuries of American history, traveling from the time of our Founders, who tried to constrain presidential power, to our modern day, when a single leader has the potential to launch nuclear weapons that can destroy much of the human race. Praise for Presidents of War "A marvelous narrative. . . . As Beschloss explains, the greatest wartime presidents successfully leaven military action with moral concerns. . . . Beschloss’s writing is clean and concise, and he admirably draws upon new documents. Some of the more titillating tidbits in the book are in the footnotes. . . . There are fascinating nuggets on virtually every page of Presidents of War. It is a superb and important book, superbly rendered.”—Jay Winik, The New York Times Book Review "Sparkle and bite. . . . Valuable and engrossing study of how our chief executives have discharged the most significant of all their duties. . . . Excellent. . . . A fluent narrative that covers two centuries of national conflict.” —Richard Snow, The Wall Street Journal

War is the most brutal of human endeavors, and I have experienced enough war to know to take cover when politicians and poets and armchair warriors speak extravagantly of patriotism and national honor. Join Major General Schloesser in the daily grind of warfare fought in the most forbidding of terrain, with sometimes uncertain or untested allies, Afghan corruption and Pakistani bet hedging, and the mounting casualties of war which erode and bring into question Schloesser’s most profoundly held convictions and beliefs. Among several battles, Schloesser takes readers deep into the Battle of Wanat, where nine U.S. soldiers were killed in a fierce, up-close fight to prevent a new operating base from being overrun. This encounter required Schloesser to make tactical decisions that had dramatic strategic impact, and led him to doubts: Can this war even be won? If so, what will it take? This book is a rare insight and reflection into the thoughts of critical national decision-makers including President George W. Bush, Secretary of Defense Robert Gates, then Senator Barack Obama, and numerous foreign leaders including Afghan President Hamid Karzai. Key military leaders—including then Chairman of the U.S. Joint Chiefs of Staff Admiral Michael Mullen, then Central Command Commanding General David Petraeus, then Lieutenant General and future Chairman Martin Dempsey, and International Security Force Commander General David McKiernan—all play roles in the book, among many others, including Chairman of the Joint Chiefs General Mark Milley and Army Chief of Staff General James McConville. Analyzing their leadership in the chaos of war Schloesser ultimately concludes that successful leadership in combat is best based on competence, courage, and character.

This book tells of General John J. Pershing; Germany's tactician, General Erich Ludendorff; General Philippe Petain; Marshal Ferdinand Foch; and President Woodrow Wilson.
