For all the stink raised about the use of US Military Drones and criticism of their increased use by Obama, casual observers might be forgiven for thinking that the use of these drones must be resulting in increased rates of reckless destruction of innocents. Well, the opposite is actually the case. Civilian deaths in Afghanistan are not only down overall (despite determined efforts by the Taliban) but the number of deaths due to the US Military (a small and shrinking fraction of all civilian deaths to begin with) has slid by 42% year on year.
Civilian deaths (which are of course life-shattering catastrophes for those who lose loved ones) are an unavoidable consequence of war so this is very positive news indeed as the drones are not only very effective against the enemy but have the added benefit of hugely reducing civilian casualties to boot.
