Since assuming office (and receiving his Nobel Peace Prize) in 2009, President Obama has massively increased the use of unmanned predator drones in what used to be known as the war against terror. According to Chris Kirk, writing in Slate , Obama has authorized five times the number of drone attacks authorized by President Bush. Liberals, who would be screaming bloody murder if it were Bush, have gone strangely (well, not so strangely) quiet about this, while conservatives are cheering on a president whose other policies they abhor.
The use of drones is not, in my opinion, inherently immoral in otherwise justifiable military operations; but the risk of death and other grave harms to noncombatants are substantial and certainly complicate the picture for any policy maker who is serious about the moral requirements for the justified use of military force. Having a valid military target is in itself not a sufficient justification for the use of weapons such as predator drones. Sometimes considerations of justice to noncombatants forbid their use, even if that means that grave risks must be endured by our own forces in the prosecution of a war.
The wholesale and indiscriminate use of drones cannot be justified, and should be criticized. This is something that Catholic intellectuals across the spectrum ought, it seems to me, to agree about. If we don’t speak, who will?
