Obama’s Final Drone Strike Data
(this is from 2017-but you get the idea)
540
"President Obama authorized his first kinetic military action: two drone strikes, three hours apart, in Waziristan, Pakistan, that killed as many as twenty civilians. Two terms and 540 strikes later, Obama leaves the White House after having vastly expanding and normalizing the use of armed drones for counterterrorism and close air support operations in non-battlefield settings—namely Yemen, Pakistan, and Somalia."
