There are a lot of books about drones. In addition to fictionalized accounts of drone use and technical manuals, numerous policy books have been written that describe drone technology, proliferation, and use. Jameel Jaffer’s The Drone Memos, is a welcome addition to the field as it provides the reader a greater awareness and understanding of not just the legal concerns surrounding U.S. drone use, but also broader strategic questions about the underlying policy and the overall efficacy of the targeted killing program.
