Drones, war, and civilian casualties: How unmanned aircraft reduce collateral damage. - Slate Magazine

From pinboard.in/deusx: "Drones kill a lower ratio of civilians to combatants than we’ve seen in any recent war. Granted, many civilians in Iraq, Afghanistan, and other such wars were killed by our enemies rather than by us. But that’s part of the equation. One reason to prefer drones is that when you send troops, fighting breaks out, and the longer the fighting goes on, the more innocent people die. Drones are like laparoscopic surgery: They minimize the entry wound and the risk of infection."
