Obama had the most sensible drone strikes into sovereign Pakistan over any other leader I know.  His sensibilities only murdered 391 civilians...


"Obama’s embrace and vast expansion of drone strikes against militants and terrorists will be an enduring foreign policy legacy. Whereas President George W. Bush authorized approximately 50 drone strikes that killed 296 terrorists and 195 civilians in Yemen, Pakistan and Somalia, Obama has authorized 506 strikes that have killed 3,040 terrorists and 391 civilians." - NYT

His use of the "secret kill list" was also one of the most sensible assassination lists any president has ever come up with.
