The true story of how lives were lost, taxpayer money squandered, and reputations destroyed as part of an ill-conceived effort to remake Afghanistan into something akin to our own image.

What started as a project to reconstruct the highway between Kabul and Kandahar evolved into an ambitious effort to provide Afghanistan with new roads, bridges, schools, clinics, power plants, and irrigation projects. These assignments fell to a Texas-based security firm, US Protection & Investigation, LLC (USPI), which in the space of a few years rose to become the most pervasive and effective paramilitary force in Afghanistan.

The initiatives required weapons, health and death benefits, ammunition, uniforms, and vehicles, which the underfunded Government of Afghanistan could not supply, but still mandated. Amendment 660 of the Foreign Assistance Act of 1972 prohibited USAID from funding these items. Aware of these Vietnam-era legal restraints, Del Spier of USPI alerted U.S. officials to the implications and was assured repeatedly that a way would be found to solve the problem.

This is the unbelievable true story of a normal American couple, Del and Barbara Spier, in unfriendly enemy territory, in the middle of a war. Unknown to Barbara, Del was forced to take matters into his own hands to accomplish U.S. objectives. He was caught in the crossfire of Afghanistan's endemic corruption, criminals, and ethnic rivalries and Washington's shifting military strategies and bureaucratic inertia.

USPI security personnel worked across the country, where they encountered ambushes, IEDs (improvised explosive devices), warlords, drug kingpins, criminals and ordinary Afghans coping with the horrors of everyday life. These horrors struck a humanitarian nerve in the Spiers and without any government assistance they provided clothing, medicine, training, fuel, food and shelter to the unfortunate.

As American troops are being withdrawn from Afghanistan, one overriding question will occupy the public for years: How could an endeavor that began with the toppling of the Taliban regime in Kabul a decade ago have evolved into the longest war in American history?

The Spiers' path ultimately led them into a protracted legal battle. USAID turned on the very company that for years had protected its construction sites in Afghanistan and enlisted the FBI and the Justice Department in a three-year, multi-million dollar investigation vendetta against the Spiers and their company. Only dramatic courtroom decisions handed down in March and July 2010 in U.S. District Court in Washington, D.C. brought the matter to a surprising conclusion.

The Spiers' tragedy is a microcosm of America's misadventure in Afghanistan.
