In February 2013, U.S. Sen. Dianne Feinstein, then-chair of the Senate Select Committee on Intelligence, went public on the collateral damage of "targeted strikes:" "The figures we have obtained from the executive branch — which we have done our utmost to verify — confirm that the number of civilian casualties that have resulted from such strikes each year has typically been in the single digits." Afterward, journalist Spencer Ackerman asked Feinstein how she could be so confident the CIA was not misleading with its drone strikes when it had misled Congress regarding its rendition and interrogation program. Feinstein replied, "That's a good question, actually. That's a good question."
On July 1, the Obama administration released information that more or less confirmed Feinstein's claim from three years ago but did nothing to address the underlying question of why those numbers should be trusted. With a long-awaited presidential executive order and a two-and-a-half-page "report" released by the Office of the Director of National Intelligence (ODNI), the Obama administration has carefully revealed some additional information about "U.S. Government" (no distinction given between CIA and U.S. military operations) "strikes" (no mention of drones or unmanned aircraft) against "terrorist targets" (broadly defined) that are "outside areas of active hostilities" (meaning Yemen, Pakistan, and Somalia).
According to the ODNI report, between Jan. 20, 2009, and Dec. 31, 2015, there were 473 strikes that killed between 2,372 and 2,581 combatants and between 64 and 116 noncombatants. According to the averages within the ranges provided by the New America Foundation, Long War Journal, and the Bureau of Investigative Journalism (found here), as of Friday President Obama has actually been responsible for 528 strikes that killed 4,189 persons, an estimated 474 of whom were civilians.
That there would be a discrepancy between U.S. government data and the numbers provided by nongovernmental research organizations is unsurprising. We have limited direct insights into how the government classifies somebody as a combatant or noncombatant, but what we do know is that official government estimates for civilian deaths have been implausibly low. Most notoriously, in June 2011, then-senior counterterrorism adviser John Brennan claimed:
"For the past year, there hasn't been a single collateral death because of the exceptional proficiency, precision of the capabilities that we've been able to develop."
In April 2013, McClatchy's Jonathan Landay wrote about classified intelligence reports that detailed who the CIA believed had been killed by 95 drone strikes conducted in Pakistan between September 2010 and September 2011. The reports note the deceased are often referred to simply as "other militants" or "foreign fighters."
Of those 95 strikes that the CIA estimated killed 482 people, only a single civilian casualty was acknowledged, which occurred in an April 22, 2011, drone strike in North Waziristan.
Given that Brennan (who oversaw counterterrorism operations from the White House) apparently actually believed that no civilians had been killed in more than a year, while the CIA believed just one out of 482 individuals killed in a one-year period was a noncombatant, the Obama administration has apparently had wholly unrealistic faith in the intelligence underlying its counterterrorism-targeting decisions and the precision of its drone strikes.
