The Drone Memos collects for the first time the legal and policy documents underlying the U.S. government’s deeply controversial practice of “targeted killing”—the extrajudicial killing of suspected terrorists and militants, typically using remotely piloted aircraft or “drones.” The documents—including the Presidential Policy Guidance that provides the framework for drone strikes today, Justice Department white papers addressing the assassination of an American citizen, and a highly classified legal memo that was published only after a landmark legal battle involving the ACLU, the New York Times, and the CIA—together constitute a remarkable effort to legitimize a practice that most human rights experts consider to be unlawful and that the United States has historically condemned.

In a lucid and provocative introduction, Jameel Jaffer, who led the ACLU legal team that secured the release of many of the documents, evaluates the “drone memos” in light of domestic and international law. He connects the documents’ legal abstractions to the real-world violence they allow, and makes the case that we are trading core principles of democracy and human rights for the illusion of security.
