Drone war proponents are facing inconvenient truths. This month, for instance, they are facing a new United Nations report showing that President Obama's escalation of the Afghanistan War - in part by an escalation in drone air strikes - is killing hundreds of children due notably to reported lack of precautionary measures and indiscriminate use of force." Drone-war cheerleaders will no doubt find this news difficult to explain away. Sen. Angus King [justified] the drone war earlier this month. "Drones are a lot more civilized than what we used to do," he told a cable television audience. "I think it's actually a more humane weapon because it can be targeted to specific enemies and specific people." Designed to obscure mounting civilian casualties, King's phrase "humane weapon" is the crux of the larger argument. The idea is that an intensifying drone war is necessary - and even humane! - because it is more surgical than violent global ground war, which is supposedly America's only other option. In a country whose culture so often (wrongly) portrays bloodshed as the most effective problem solver, many Americans hear this now-ubiquitous drone-war argument and reflexively agree with its suppositions. By deliberately ignoring any other less violent option, drone-war proponents who employ choice-narrowing language are ... precluding America from making more prudent, informed and dispassionate national security decisions - the kind that might stop us from repeating the worst mistakes of our own history.
