"Beyond the political consequences, the drone program also imposes severe bureaucratic costs. Within the U.S. Intelligence Community, various lethal targeting programs are heavily classified, compartmented, and SAPed — meaning, they are mostly closed off from each other. This is one reason why the CIA and JSOC maintain separate, non-overlapping kill lists in Yemen. It also means it is practically impossible for anyone, in any position including the top of the Office of the Director of National Intelligence, to exercise proper oversight over the program. In other words, we have created an unaccountable killing machine operating at an industrial scale, to borrow CNAS President John Nagl’s phrasing."
