Prologue — Ninety Seconds
At fourteen minutes past eight on the morning of the twenty-eighth of February, 2026, the sirens opened across the State of Israel, and I did what every parent in this country is trained to do. I counted. You have ninety seconds, and you count them, because counting is the one thing you can control. My wife took the youngest. I carried the next. The older two knew the drill; they have known it since we moved here. We sat on the concrete floor of the sealed room and waited for the sound that would tell us whether the mathematics of interception had worked in our favor. My youngest asked whether the boom was thunder. I told her yes. It is the simplest lie and the kindest one.
Six months earlier I had brought my family from Philadelphia to Israel, after thirteen good and safe years in which I could read about this part of the world from a distance that made the reading comfortable. I had believed in a country I was not living in; I had argued for its defense from an ocean away. That is a particular kind of faith, sincere but untested, the kind that costs nothing but conviction. Then I came home, not to America, but here, because there is a difference between believing a thing should be done and standing where the consequences of doing it arrive overhead. I had wanted to stop describing the fire and sit in it. That morning the fire came.
A doctrine is an abstraction until it arrives at the speed of sound. Everything in the pages that follow, every argument about deterrence and victory and the true cost of half-measures, was written so that fewer fathers in fewer rooms would have to count to ninety. That is the whole of it. That is what the abstraction was always for. I wrote most of this book before that morning; you are reading it after. By the time it reached you the war had come and, by every measure the parades could see, been won. Whether we also won the victory is the harder question, the one this book exists to ask, and the one I could not honestly answer until I had sat on that floor and counted to ninety with my children.
Chapter One — A Suburban Awakening
There is an old Hasidic parable about two ways to keep warm on a winter night. A man who is cold can wrap himself in a heavy fur coat, or he can gather wood and light a fire. The fur coat warms the one man who wears it. The fire warms the man who builds it and everyone else in the room. The Hasidim had a name for the man who chooses the coat and lets the rest of the house shiver. They called him a tzaddik im peltz, a righteous man in a fur coat, righteous enough to keep himself warm and content enough to do nothing for the cold all around him.
I grew up in a country wrapped in the warmest coat ever stitched. America in the 1990s had won its great war, outlived its great rival, and decided, not unreasonably, that history was finished and the cold was someone else’s problem. My corner of it, a quiet street in Yardley, Pennsylvania, was the lining inside the lining: good schools, mowed lawns, a childhood whose worst emergencies happened on a kickball field. We were warm. We assumed the warmth was the natural condition of the world, rather than a fire that someone else was tending, or failing to tend, a long way from our living rooms.
This book is the story of how I came to understand that the coat is a lie. Not a comfort, a lie, because the cold does not stay outside, and a village where every man owns a fur coat and no man will build a fire is a village that freezes one house at a time and calls it peace. What follows is my education in the difference between wearing the coat and lighting the fire, and it began on the afternoon I walked through my own front door and found my mother weeping at the television. I was nine years old.
The fire I would spend the rest of my life learning to build had just been lit, half a world away, by men who meant to burn down everything I loved.
The first-time political violence entered my home, it arrived on a television screen on a cold November afternoon in 1995. I was nine years old, walking through the front door of our house on Hunt Drive in Yardley, Pennsylvania, consumed by some forgotten elementary school grievance, a dispute over a kickball game, a slight on the playground, the kind of trivial drama that fills a child’s entire world. I remember the weight of my backpack and the sting of injustice in my chest. Then I saw my mother.
She was sitting on the edge of the living room sofa, her hands pressed to her mouth, her eyes fixed on the television. She was in tears. On the screen, the familiar, authoritative face of Peter Jennings presided over scenes of chaos. The images were grainy, broadcast from half a world away, showing flashing lights and panicked crowds in a city square I didn’t recognize. The chyron at the bottom of the screen read: TEL AVIV.
My own small world of fourth-grade problems evaporated. My mother, the steady center of our family’s universe, rarely cried. Her distress was an alarm bell, signaling a disruption far more significant than anything I had ever known. She explained, her voice thick with shock, that the Prime Minister of Israel, a man named Yitzhak Rabin, had been shot. Assassinated. He had been speaking at a peace rally, surrounded by people who wanted to believe that a generation of war could finally end. And a man from his own country, a fellow Israeli, had killed him for it.
I didn’t understand the intricacies of the Oslo Accords or the bitter divisions within Israeli society. But I understood the scene on the screen. I understood the finality of the word assassinated. And I understood the raw grief on my mother’s face. My childish indignation dissolved into a profound and unsettling confusion. It was my first lesson in proportion. The world contained sorrows so vast they could make a mother weep in her living room in suburban America, sorrows that made a bad day at school feel like nothing at all.
For six years the world felt like a powder keg, and I felt like one of the few people I knew who could hear the fuse hissing. Then, on the morning of September 11, 2001, it went off.
I was in class when the first reports came in. The initial news was confused, a small plane, an accident. Then the second plane hit, and we all knew. The teachers huddled together, their faces a mixture of fear and disbelief. They sent us home. I walked into my house to find my parents, just as they had been six years earlier during the Rabin assassination, transfixed by the television. But this was different. The horror wasn’t in Tel Aviv. It was in New York City, a place I had visited a dozen times. It was at the Pentagon, the heart of American military power. The grainy footage of falling bodies and collapsing steel felt both hyper-real and completely impossible.
That night, the conversation at the kitchen table was not about grief, but about war. My father laid it out in stark, simple terms. He told me about Islamist extremism, about an ideology that viewed America, with its freedom, its culture, its power, as the Great Satan, an enemy that must be destroyed. He explained that this was not a conventional war against a country with an army and a capital. This was a war against a global network, a death cult that celebrated martyrdom and sought our annihilation.
In that moment, the disparate threads of the past decade braided themselves into a single, terrifying cord. The Rabin assassination, Oklahoma City, the embassy bombings, the USS Cole, the suicide bombers in Israel, the murder of Massoud, and now the smoking ruins of the World Trade Center—they were not separate events. They were all battles in the same war, a civilizational struggle between the forces of liberal modernity and the forces of a totalitarian, medievalist ideology. The comfortable illusion of the 1990s, the American vacation from history, was officially over. The war was here.
What I learned at American University, I learned mostly by discovering what it could not teach me. I arrived in Washington in 2003 as an eighteen-year-old with a wrestler’s discipline and a head full of September 11, certain that the capital was where you went to fight the war of ideas I had decided to join. I found instead a place that treated the war as an abstraction. The professors who lectured me on the Middle East seemed to regard terrorism as a regrettable weather pattern, a thing that happened rather than a thing that people chose, financed, and justified. They taught the conflict as a tragedy with no villains, which is to say they taught it as a lie.
I left the wrestling team and pivoted, with the same intensity I had once spent on the mat, into the only thing that felt real: the actual study of how the threat worked. I found it not in the classroom but a few blocks away, at the Inter-University Center for Legal Studies, where Professor Yonah Alexander and Professor Edgar Brenner took a chance on a brash teenager and gave him a front-row seat to genuine counter-terrorism analysis. They had been studying political violence with rigor for decades before it was fashionable, and they taught me the two things the university could not: that the threat was real, and that scholarship without consequence is only a more elaborate way of looking away.
So I did the thing that baffled my advisors. I took a leave of absence, then another, and gave more and more of myself to the real work and less and less to the degree. The classroom became a place I visited between the things that mattered. I was getting an education in Washington, but it was not the one printed on the syllabus. It was the slow, infuriating discovery that the city I had come to in order to fight had made a comfortable profession out of not fighting.
That was the lesson, and it was the one that eventually drove me across an ocean. I had become fluent in the theory of the fight, surrounded by people who had built whole careers on the theory, and I had begun to grasp that you could spend a lifetime in those rooms and never once touch the reality. I did not want a career in the theory. I wanted the reality. And the reality was not in Washington.
A century before I was born, at the far end of my own state, there was a town that refused to believe its own warnings. Fourteen miles above Johnstown, Pennsylvania, an earthen dam held back a private lake stocked with game fish for a club of Pittsburgh millionaires. The men who owned it had lowered its crest, clogged its spillway, and let its drain pipes rust, and for years the engineers who studied it said plainly that one day it would give way. The valley below had heard the alarm so many times that the alarm had become a joke. Every hard rain sent the same rumor down the line, the dam is going, and every time the rumor proved false the people believed it a little less, until belief itself had drained away.
On the last day of May in 1889, after the heaviest rain anyone could remember, the warnings went out once more by telegraph, the final one reading: the dam is becoming dangerous and may possibly go. The operators had sent that message before. Almost no one moved. A few hours later the dam failed, and twenty million tons of water came down the valley at the speed of a train and wiped the town off the earth, and more than two thousand people died in a single afternoon. For one hundred and twelve years that day stood as the deadliest day of man-made civilian death and disaster in American history. The record was broken on a Tuesday morning in September, by men with box cutters, while a different country told itself a different version of the same comfortable lie.
That is what the long quiet of the 1990s was, I understand now. It was the telegraph clattering in an empty office. The first bombing of the World Trade Center, the embassies blown open in Africa, the hole torn in the side of the USS Cole, a prime minister shot dead at a peace rally, the bombers in the cafes of Jerusalem, each one a rider sent down the valley carrying the same message, and each one filed beside the last false alarm by a civilization that had grown too warm to credit its own eyes. The fuse I could hear hissing was real. The dam was already cracking. The water was already moving.
All that was left to decide was how many of us would still be standing in the street, insisting it was only another rumor, on the morning it finally came down.
