Forget about nuclear missiles, the decisive weapon of the 21st Century is the car bomb. After Iraq we now know you can defeat a superpower, start a civil war or just blow up your own Government with a trunk load of home-made explosives and a battered old car. From the Middle East, Oklahoma, Ireland and the streets of the City of London the car bomb has shaped the river of human conflict. Even today the car bomb remains the number one terrorist threat across the world. In this startling film ex-CIA agent Robert Baer, for the first time uncovers the history of this extraordinary weapon. With shocking footage of car bomb attacks and penetrating interviews with car bombers, Baer reveals how the century of the car turned into the century of the car bomb - and how the dream of freedom turned into a nightmare.
