President Obama's nomination for head of the CIA is his right-hand man on the US drone war on al Qaeda. An outspoken supporter of America's post 9/11 anti-terrorism drone program, Brennan has been outspoken on the topic often talking in more concrete terms than the administration was ever willing to do. Brennan's nomination looks like an attempt from the Obama administration to clean up their drone policy and might finally signal that they are ready to shed more light on the topic that will surely be a talking point for years to come.
Brennan has already established his basic tendencies towards policies and other things like that. He has openly supported secrecy and such things before, and there is no valid reason to believe that he will suddenly have a personality shift to become more open about such things now. Obama and the administration will remain secretive.
Brennan has already lied about the role of drones killing civilians in Pakistan, and there's no doubt that he supports the administration's stand that they can kill US citizens who are enemy combatants with drones, in spite of the promise of due process.
Based on the administration's record, I foresee no change on the openness on the use of drones.
Brennan has already lied about the role of killing civilians in Pakistan, and he no doubt supports the administration's view that they can kill American citizens in combat against the US without judicial oversight.
Obama has shown little concern for due process up to this point, and there is little reason to believe that he or anyone he has nominated will begin to scrupulously show concern at this point.
