And so the Dirty War provides a model for how to dismantle a terrorist organization.
The trick is to not mind killing, and to expect dying.This came clear to Kevin Fulton on the day his cover as an IRA man collapsed. It happened inside an IRA safe house in north Belfast, in 1994. Fulton sat facing a wall, blindfolded. Curtains shut out the pale light of winter. Bottles lay scattered on the floor, and the place stank of stale beer. An interrogator paced the room, his boots scuffing against the floor. He said, “I know what yer done, boyo.”
He pressed a thick index finger against Fulton’s temple, hard, then leaned in close to Fulton’s ear and murmured a series of threats:
The IRA hunts down all snitches and executes them. Two quick bullets in the brain. Remember the boy from County Armagh who left behind the pregnant wife. Remember the boy from County Louth who left seven children mewling for a father. Remember them all.British authorities had recently picked up Fulton for questioning. Now the IRA, which had begun to suspect him of being a British agent, wanted to know why.
Again, the finger to the temple.
“What did you tell them?”
Fulton knew the voice, and its owner: Scap, one of the IRA’s most feared interrogators. Fulton had once helped prepare safe houses for such interrogations, and knew that sometimes Scap’s subjects survived. Sometimes not.
Colleagues called both men “hard bastards”—true IRA boys, mothered by terrorism. They killed for the cause, time and again. But British spies had infiltrated the IRA, spreading deceit and rumors of deceit. The IRA had turned against itself. Scap couldn’t say for sure who fought on his side.
The interrogation dragged on for hours. Fulton remained outwardly calm, and denied everything. Inwardly, though, he felt sick. He’d been spying on the IRA for a decade and a half, and he knew that if Scap broke him—if he admitted anything—he’d be a dead man—own a hole,” in IRA slang.
So throughout the interrogation, Fulton sat stone-faced, blindfolded, and facing the wall. Double blind. He held tight to his secret: yes, he was a British spy.
But then,
so was his interrogator..."

"After the Long Kesh internment debacle, the IRA gained ground against the British. On patrol in Belfast, British soldiers dodged stones by day and firebombs by night. Troops in armored Rovers and protective helmets made no good friends; they only made good targets. They needed a better strategy, and a powerful personality to implement it. And they soon found the man for the job: Brigadier General Frank Kitson.
Kitson rolled into Northern Ireland in the early 1970s with considerable experience battling insurgencies in Kenya, Malaya, and elsewhere. He had learned valuable lessons, particularly in Kenya in the 1950s battling the Mau Mau, a band of rebels fighting for independence. He had rounded up suspected Mau Mau supporters, who then endured interrogation and torture at the hands of the British authorities. The Mau Mau couldn’t match the British militarily, so they resorted to guerrilla tactics, hiding in the hills and striking from the shadows. But Kitson followed them there, recruited locals with money and idealism, and infiltrated the insurgent ranks. With layer upon layer of sabotage, subterfuge, and duplicity, he obliterated the Mau Mau.
Kitson’s methods proved so effective that he wrote a now-classic counterinsurgency book, Low Intensity Operations: Subversion, Insurgency, Peacekeeping, which laid out principles now being followed by American forces in Iraq. By the time Kitson arrived in Northern Ireland, Low Intensity Operations had become his instruction manual for war there. He stayed for only about two years, but in that brief period he set a new course for the British army that, for better or worse, carried it through the Troubles. By 1978, using tactics endorsed by Kitson, the army had for years been regularly stopping vehicles at checkpoints and randomly arresting drivers to screen them. One of the men hauled in that year was Freddie Scappaticci, fresh from his beating by the IRA...
...So it started. He delivered a package—a pistol and bullets—across town. He made another delivery, then another. Always on time and dependable. The jobs escalated in subtle increments, and as his errands reached farther, the packages grew deadlier. Bullets became pipe bombs, and pipe bombs became car bombs...
...Each night Fulton rocked himself to sleep repeating the mantra his handlers had given him: “The greater good. The greater good. The greater good.” He and Scappaticci engaged in a difficult mathematics, a calculus of souls. If a man kills thirty people to save 3,000, has he done right? What about thirty for 300? Or thirty for thirty-one?
At one point I asked Fulton whether, in light of the human toll he would exact in the course of his career, someone could have served the greater good by killing him as a young man. I meant the question to be rhetorical. But Fulton just nodded.
“Yes,” he said..."
