Welcome to the wartime contracting bazaar in Afghanistan. It is a virtual carnival of improbable characters and shady connections, with former CIA officials and ex-military officers joining hands with former Taliban and mujahedeen to collect US government funds in the name of the war effort.

In this grotesque carnival, the US military’s contractors are forced to pay suspected insurgents to protect American supply routes. It is an accepted fact of the military logistics operation in Afghanistan that the US government funds the very forces American troops are fighting. And it is a deadly irony, because these funds add up to a huge amount of money for the Taliban. “It’s a big part of their income,” one of the top Afghan government security officials told The Nation in an interview. In fact, US military officials in Kabul estimate that a minimum of 10 percent of the Pentagon’s logistics contracts–hundreds of millions of dollars–consists of payments to insurgents.

The real secret to trucking in Afghanistan is ensuring security on the perilous roads, controlled by warlords, tribal militias, insurgents and Taliban commanders. The American executive I talked to was fairly specific about it: “The Army is basically paying the Taliban not to shoot at them. It is Department of Defense money.” That is something everyone seems to agree on.

But the heart of the matter is that insurgents are getting paid for safe passage because there are few other ways to bring goods to the combat outposts and forward operating bases where soldiers need them. By definition, many outposts are situated in hostile terrain, in the southern parts of Afghanistan. The security firms don’t really protect convoys of American military goods here, because they simply can’t; they need the Taliban’s cooperation.
