That article is grossly inaccurate. It's one thing to say "Obama applied hard power more than was expected" as opposed to "He was worse than Bush" which is completely unjustified. There is absolute no equivalence between drone usage and the two ground wars engaged by Bush. The 2 week Shock and Awe campaign in Iraq dropped more ordinance and killed more people than 8 years of drones. And the drone campaigns were mostly carried out with the private consent of the nations with targets. And saying the Libyan Civil War was "US-led" is just a complete lie. It was most directly lead by Libyans, but the air campaign was led by France.
