How We Lost the War We Won

As the Taliban insurgency spreads, it has fallen victim to the tribal rivalries and violent infighting that are endemic to Afghanistan, which is home to hundreds of distinct tribal groups. "The leadership is totally fragmented," a senior U.N. official says. "There is a lot of criminality within the Taliban." With the targeting of civilians now sanctioned by the Taliban, top commanders compete for prize catches, stopping cars in broad daylight and checking the cellphones of foreigners to determine if they are worthwhile captives. As we drive deeper into Ghazni, we are entering territory where such factionalization is now as lethal as the rocket launcher stuffed in the Corolla's trunk.

In the middle of a sandstorm, we head to a local shop, pulling up with the PKM in plain view and the Taliban chants blaring from the car's speakers. The people in the shop greet Yusuf warmly. He buys shoulder straps for AK-47s. Then, as we're passing through a nearby village, we are stopped by a bearded man on a motorcycle. An AK-47 is slung over his shoulder, his face partially concealed by a scarf.

He demands to know who I am. Shafiq tells him I am a guest. The man asks me if I am Pashtun. "Pukhtu Nayam," I say, drawing on my Berlitz lessons. "I am not Pashtun." He glares at me and rides off.

Arriving at another mosque, we find a dozen men inside. A large shoulder-fired missile is on the floor, an anti-armor weapon. Shafiq tells me we are waiting to meet the commander who will approve my trip.

This is news to me. I thought my trip had already been approved by the Taliban defense minister. Suddenly, as I am talking to one of the fighters, the angry man on the motorcycle bursts in holding a walkie-talkie. He barks at the fighter to stop talking to me until the men's commander shows up. A judge, he says, will decide what will happen to me. Upon hearing the Pashtu word qazi, I start to panic. As Shafiq made clear earlier, a meeting with a judge could end with decapitation.

I am ordered to get into a car with the angry man and the other strangers, who will take me to the judge. To my alarm, Shafiq says he will join Yusuf, who is praying in the mosque, and catch up with us later. He seems to be washing his hands of me.

I have been held by militias in both Iraq and Lebanon, but in those situations I could speak the language and talk my way out of trouble. Now I am in one of the most desolate places I have ever seen, far from any help and unable to speak more than a few garbled words of Pashtu. Trying to contain my mounting sense of helplessness, I tell Shafiq that I am not leaving him — I am his guest. Once I am out of his control, I will be at the mercy of men who kill almost as routinely as they pray. Brandishing their rifles, the men shout at me to get into their car.

Yusuf comes out and tells me to get into our Corolla. He won't leave me, he says. He puts another man with an AK-47 in the car to guard me. As I wait, a standoff ensues. Frantic, I send text messages to my contacts back in Kabul to tell them I'm in trouble. In the tense silence, my guard's cellphone abruptly goes off: The ringtone is machine-gun fire, accompanied by a song about the Taliban being born for martyrdom.

My mouth goes dry from fear; I feel as though I have lost my voice. My friend in Kabul who helped arrange the trip manages to get through to Shafiq. He tells him he should not leave me, that I am Shafiq's responsibility and he will hold him personally responsible if anything happens to me.

We sit in the car for more than an hour, windows up. The sandstorm is still raging, and it's impossible to see more than a few yards. Outside, men with guns flicker into view, only to vanish in the blinding haze. Finally, Shafiq tells me I can get out. The angry man and his companions depart, taking the rocket launcher with them. Thinking it is over, I put my hand on my heart as they leave, to indicate no ill will. Then Shafiq tells me there has been a change of plan. He has been ordered to escort me to visit a rival commander — a man called Dr. Khalil — who will determine what will happen to me.

I later learn that I have been caught in the midst of the bitter and often violent infighting that divides the Taliban. Ibrahim's recent injury, it turns out, was the result of a clash between his forces and a group of foreign fighters under the command of Dr. Khalil. The foreigners wanted to close down a girls' school, sparking a battle. Two Arabs and 11 Pakistanis commanded by Dr. Khalil had been killed by Ibrahim's men.
