The foxhole’s observation slit gave a view of the Davis Pike, hazy now in the dawn mist. On the ledge of packed earth that formed the base of the slit, Bar Abbas laid out a pair of binoculars, a pack of cigarettes, a coffee thermos, and last but not least, a remote-control box.

The green lamp on the remote control lit as soon as Bar Abbas switched it on, and when he pressed the test button the lamp flashed, indicating that the detonator circuit on the IED was live. A red lamp would let Bar Abbas know if and when Samir pressed the SEND button on his cell phone. After that, he wouldn’t have to do anything; the bomb would use the cell’s GPS to decide when to detonate. But the remote control also had a second button, under a safety catch, that would allow Bar Abbas to detonate the bomb manually if the red lamp failed to light.

Bar Abbas’s own cell phone vibrated silently in his jacket. It was a text message from a confederate in the Green Zone: SARACENS WILL DEPART 0700. Assuming normal traffic, drive time from the Green Zone to this kill zone should be about thirty minutes, so he had roughly two hours to wait.

There was room in the foxhole for at least three men, but Bar Abbas had insisted on privacy. While his subordinates shivered in the open air, he poured himself coffee and took a book from a satchel at his feet. In the gray dawn half-light he studied the title and author on the book’s cover: The Osama bin Laden I Know, by Peter Bergen.

A truck rumbled by on the highway below. Bar Abbas lit a cigarette and began to read.

The four Humvees were lined up in front of the Watergate Hotel. Three of them were what the Marines called “luxury models,” with bolted-on side and rear armor plating, bulletproof windows, and an armored turret surrounding the roof-mounted .50-caliber machine gun.

Mustafa, Samir, and Amal were each assigned to one of the armored Humvees. Mustafa would ride in the lead vehicle with Lieutenant Fahd. Humvee number two was the unarmored model.

Amal was assigned to Humvee number three with Salim, Zinat, Umm Husam, and a Sergeant Faris. Zinat offered to drive, but Sergeant Faris insisted on taking the wheel himself, and since Lionesses were not allowed to operate heavy weapons except in emergencies, that put Salim on the .50-caliber. “Ah well,” Zinat said, after Umm Husam claimed the other front seat, “at least we’ll have a nice view.” She tried to show Amal how the gunner’s sling would dangle Salim’s buttocks directly before their eyes, but Amal’s attention was focused on the turret armor, which struck her as inadequate. Salim’s head and upper torso would still be exposed, especially to a shooter firing from an elevated position.

Samir was assigned to the fourth Humvee, which had a sign mounted between its taillights reading AMERICA, TAILGATE AND WE WILL KILL YOU.

They had been issued helmets and flak jackets. Samir found the body armor constricting and pointless, so he stripped it off while he had a last smoke and then, when the order came to get into the vehicles, tried to leave it behind. The Marines were looking out for him, though, and one of his Humvee-mates, Private Dimashqi, patted him on the shoulder and handed the flak jacket back to him. “I know it’s a pain in the ass,” the private said, “but we really do want to keep you safe, sir.”

“Thanks,” Samir said glumly.

Colonel Yunus came out to see them off. He made eye contact with Mustafa and pressed his palms together in front of his chest. Mustafa smiled and returned the gesture, and the colonel nodded to Lieutenant Fahd.

“OK, let’s roll,” the lieutenant said.

Their air escort, a Shaitan missile-equipped helicopter gunship, was hovering over the Kennedy Arts Center. As the Humvee convoy rounded the Arabian embassy and entered the on-ramp for the Theodore Roosevelt Bridge, the pilot dipped the chopper’s nose in acknowledgment and flew out over the Potomac ahead of them.

Lieutenant Fahd, playing tour guide, explained that the bridge was named for the first American president to pay a state visit to the UAS. Teddy Roosevelt had spent little time in Arabia itself; instead he and Ibn Saud had gone down the East African coast for six weeks of big-game hunting in Kenya.

The bridge passed over an island in the middle of the river. The island too was named for Roosevelt and prior to the invasion it had been a nature preserve. Unfortunately the forest cover had attracted insurgents, and after a pair of former Minutemen had been caught laying dynamite under the bridge piers, Army engineers had been dispatched to the island. They’d chopped down every tree and shrub within two hundred meters of the bridge and used flamethrowers on the rest. Looking ahead, Mustafa could see that similar measures had been employed on the Virginia shoreline—and not just on the foliage. Many of the high-rises in downtown Arlington were blackened husks, and those that hadn’t burned were heavily damaged by artillery and rocket fire. “Is that from the 2004 assault?”

“Some of it,” Lieutenant Fahd said. “Some of it dates back to the initial invasion, and some is more recent—Arlington has always been a trouble spot. Despite how it looks, we do try our best to minimize collateral damage, but there are limits to how surgical you can be with high-explosive munitions in a built-up area like this.”

The road circled north and west around the urban core. The Humvee gunners kept their weapons trained on the broken skyline and watched for snipers. Zinat, ogling Salim’s butt, gave Amal a nudge as his hips swiveled along with the turret. Amal ignored her. Like the gunners she was focused on the tall buildings, appalled not by the destruction but by the number of viable sniping perches that remained among the wreckage. Minimizing civilian casualties was all well and good, but if you were going to raze a city anyway, why not do a more thorough job?

For the first kilometer no one attacked them. Then they drove past a housing subdivision that had been blasted flat during an encounter between the Virginia Sons of Liberty and the Seventh Marine Regiment. A gang of little kids were playing Patriots and Muslims in the rubble-strewn field, darting from cover to cover and shooting one another with rifles made from sticks.

Lieutenant Fahd keyed his radio. “Hold fire, hold fire,” he said. “These are noncombatants.”

The Humvee gunners held their fire. The kids, being kids, showed less restraint. When Salim snapped a mock salute at one mini-patriot in a newspaper tricorne, the boy threw a rock at him. The kid had a good arm; the rock struck the lip of the turret armor and bounced up, nearly catching Salim in the face. “You little shit!” Salim said—a sentiment echoed by Amal inside the Humvee. But Salim was laughing, and he kept the .50-caliber aimed safely skyward, even as the other kids started throwing rocks too.

“What’s that phrase they’re chanting?” Mustafa asked.

“ ‘Sand nigger,’ ” said Lieutenant Fahd. He added drily: “It’s a term of endearment. They are comparing us to the noble slaves who built this country.”

Mustafa got the joke, but he didn’t laugh. He didn’t wish to be a spoilsport, and he really did believe that the military had done the best it could here with the tools available. Nevertheless, as the convoy continued on its way, passing more and more scenes of devastation, the thought was inescapable: On the Day of Judgment, whatever other achievements might be credited to the Coalition, nation-building wouldn’t be one of them.

The rising sun had burned off the fog and there was enough light inside the foxhole now that Bar Abbas could read without squinting. He’d paused to light a fresh cigarette and pour the last of his coffee when his cell phone vibrated again.

He had two incoming text messages. One was from the secondary ambush team, confirming that they were in place, ready to finish off any Marines who managed to escape this kill zone.
