WASHINGTON D.C.: The US government has released a once-secret policy document once dubbed “the playbook” that shows how officials select drone targets in areas outside war zones and the key role the president has in the process. The 18-page Presidential Policy Guidance (PPG), published on Saturday (Sunday in Manila) by the American Civil Liberties Union, provides more details than the government had previously revealed on how drone strikes are approved. “Actions, including lethal action against designated terrorist targets, shall be as discriminating and precise as reasonably possible,” the PPG states. President Barack Obama typically must personally sign off on plans to strike terror suspects who are located outside war zones in which America is officially fighting. Such zones include Pakistan, Libya, Somalia and Yemen. Strikes in combat theaters such as Iraq, Syria and Afghanistan are controlled by the military.
