Blowback - a term originally coined by the CIA, to describe the unintended consequences of American policies. In his devastating critique, Chalmers Johnson shows how this concept has challenged America's superpower status in the twenty-first century.In essence, Blowback updates the old adage that you reap what you sow; except that in the case of US foreign policy, the American people are often unaware of what has been sown on their behalf. And while the US government condemns attacks against American citizens and property as being the work of 'terrorists' and 'rogue states', Johnson shows that they are often acts of blowback from earlier covert operations.Blowback is a much needed wake-up cal for American policy makers - a warning to demobilise the global empire before the full force of blowback takes effect.
