The car bomb, or VBIED (Vehicle Born Improved Explosive Device), if you have an MSAF (Milspec Acronym Fetish) is the guerrilla smart bomb. In its more basic form, it marries the mundane infrastructure of urban life like trucks and driveways, to easily available explosives like ANFO and diesel fuel, to a deadly weapon. Whether abandoned in a parking garage or brazenly crashed through the front gates of an embassy by a suicide bomber, the car bomb is a way for poor organizations to hit sensitive targets with precision.
Davis rolls through the long history of the car bomb, from its invention by Italian anarchist Mario Buda, to its perfection by the Zionist terrorist group Irgun, to its proliferation across the world in the hands of the Tamil Tigers, the IRA, and Al Qaeda in Iraq. There's an odd tonal disconnect between coldly clinical history and near-conspiratorial glee at CIA blowback, as car bombs disrupt French, British, and American imperialism, but in a short and breezy book the style mostly works.
Davis is by training a Marxist urbanist, and he's best in noting that car bombs are more than cheap precision weapons used to hit hard targets like embassies and barracks. The generalized threat of car bombs is paralyzing, demanding a 'Ring of Steel' to protect downtowns and upper class districts. Indiscriminate in their death, car bombs can be used against soft targets like schools and markets to foster ethnic violence and sidetrack peace negotiations. Finally, given the ease by which vehicles circulate through cities, there's no way to ensure security. Buda's wagon is the hotrod of the apocalypse.
There's not much original research in this book, and in some ways the threat of car bombs has been supplemented by the pure kinetic energy of ISIS vehicular attacks. Still, afun little military history worth a read.
