Its a shame that you didn't have Obama more on your minds as he was dropping drone bombs on the Middle East during his tenure. A few quotes from an article by the Council on Foreign Relations:

The 542 drone strikes that Obama authorized killed an estimated 3,797 people, including 324 civilians.

...he reportedly told senior aides in 2011: “Turns out I’m really good at killing people. Didn’t know that was gonna be a strong suit of mine.”

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
