John Brennan, the counter-terrorism adviser nominated by President Obama to be the next head of the CIA, has reportedly agreed to exempt agency strikes in Pakistan from a new set of rules that attempts to justify and codify the use of drones to assassinate leaders of al-Qaida and other terrorist groups around the world, including US citizens. The dispensation to allow so-called targeted killing to continue without restrictions in Pakistan removes from the new set of guidelines the most important and controversial target of drone strikes. In the past few weeks the frequency of US strikes in the tribal areas of northern Pakistan ... has been stepped up. The pass would allow the US to sustain heavy bombardments of the tribal regions via drones launched from bases in Afghanistan for another year or two, ahead of the withdrawal of most American forces from that country in 2014. The decision to give the US targeted-killing programme the appearance of legal propriety by codifying it, and now the temporary exemption granted from that codification to Pakistan, were both taken by Brennan. A counter-terrorism expert with 25 years experience in the CIA, his nomination to run the agency has raised eyebrows among civil liberties groups because of his senior role in the CIA under George W Bush at a time when torture was used on terror suspects and because of his fondness for drone strikes. The UK-based Bureau of Investigative Journalism estimates that there have been 362 drone strikes in the country since 2004 - 310 of them launched on Obama's watch. The strikes have killed up to 3,461 people.
