Kill Chain uncovers the real and extraordinary story of drone warfare, its origins in long-buried secret programs, the breakthroughs that made drone operations possible, the ways in which the technology works, and, despite official claims, does not work. Through the well-guarded world of national security, the book reveals the powerful interests - military, CIA, and corporate - that have led the drive to kill individuals by remote control. Most importantly of all, the book describes what has really happened when the theories underpinning the strategy - and the multi billion-dollar contracts they spawn - have been put to the test.
