Charlie Wilson's War

I'm sure nothing could go wrong here.

TIRIN KOT, Afghanistan — The most powerful man in this arid stretch of southern Afghanistan is not the provincial governor, nor the police chief, nor even the commander of the Afghan Army.

It is Matiullah Khan, the head of a private army that earns millions of dollars guarding NATO supply convoys and fights Taliban insurgents alongside American Special Forces.

In little more than two years, Mr. Matiullah, an illiterate former highway patrol commander, has grown stronger than the government of Oruzgan Province, not only supplanting its role in providing security but usurping its other functions, his rivals say, like appointing public employees and doling out government largess. His fighters run missions with American Special Forces officers, and when Afghan officials have confronted him, he has either rebuffed them or had them removed.
