 The report stated that the number of arbitrary civilian deaths, the tactics used (such as follow-up attacks targeting individuals helping the wounded) and the violation of Pakistani sovereignty meant that some of the strikes could be considered as unlawful executions and war crimes.In May 2014, the targeted killing program was described as "basically over," with no attack having occurred since December 2013.The lull in attacks coincided with a new Obama Administration policy requiring a "near certainty" that civilians would not be harmed, requests from lawmakers that the drone program be brought under operational control of the Department of Defense (for better congressional oversight), a reduced US military and CIA presence in Afghanistan, a reduced al-Qaida presence in Pakistan, and an increased military role (at the expense of the CIA) in the execution of drone strikes.
