Forget about nuclear missiles; the decisive weapon of the twentieth 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 homemade explosives and a battered old car. From the Middle East, Oklahoma, Afghanistan and most recently New York's Time Square, the car bomb has shaped human conflict. Even today the car bomb remains the number one terrorist threat across the world. In his startling film CAR BOMB, ex-CIA agent Robert Baer, whose life was depicted by George Clooney in the Oscar-winning movie SYRIANA, uncovers the history of this extraordinary weapon for the first time. Starting, perhaps surprisingly, at 12:01 p.m. on September 16, 1920 outside the J.P. Morgan bank on Wall Street, where a horse-drawn wagon laden with dynamite was detonated killing 38 people and injuring 143 more, Baer reveals how the century of the car turned into the century of the car bomb, with shocking footage of attacks and penetrating interviews with car bombers.
