Obama didn't seem to care.Probably because the role of president puts you in an unavoidable position where innocent people will die.
the same scenarios could happen with Warren and Bernie unless they go full pacifist. The enemy hides amongst innocent civilians. It's not like they are in separate bad guy headquarters away from innocent life. Is Bush more guilty than others? Sure but is there any US president in recent times that didn't get innocents killedwhen fighting terrorist?
also I don't think they take the news of "we got the target but there was a lot of collataral" is no big deal. I'm sure it fucks with their mental health. Someone like Trump though? He wouldn't care.
"Kill chain" operations expanded under Barack Obama, who authorized roughly 500 drone strikes outside active conflict zones during his presidency, 10 times the number under George W. Bush.
From his first days as commander in chief, the drone has been President Barack Obama's weapon of choice, used by the military and the CIA to hunt down and kill the people his administration has deemed — through secretive processes, without indictment or trial — worthy of execution. There has been intense focus on the technology of remote killing, but that often serves as a surrogate for what should be a broader examination of the state's power over life and death.
If Obama apologized for 1 civilian drone victim every day, it would take him 3 years
General Stanley McChrystal (Ret.), who led coalition forces in Afghanistan and was the head of the U.S. Joint Special Operations Command, has said that drone strikes create "a perception of arrogance... a perception of helpless people in an area being shot at like thunderbolts from the sky by an entity that is acting as though they have omniscience and omnipotence." The testimonies in this report confirm his observations. Yaslem Saeed bin Ishaq, whose son was killed in an August 1, 2013 U.S. drone strike said: "They just kill. They do not know what havoc their missiles have caused. They are unaware of the suffering they create for our families." Moqbel Abdullah Ali al-Jarraah, a villager from Silat al-Jarraah, where a January 23, 2013 U.S. airstrike hit a civilian house, observed: "I believe that America is testing its lethal inventions in our poor villages, because [it] cannot afford to do so at any place where human life has value. Here, we are without value.
