Why do they hate us?
As weapons program symbols go at the DoD, this isn't any more morbid or aggressive than most. Still, I'd have to think that, at least for the recipients of our UAV strikes, this would be in poor taste. These aircraft are so small and stealthy that the people in the area may not know they are under attack until they hear an explosion. Combine that with our propensity for using them in countries with whom we're not at war, and I think Greenwald's rhetorical question is a good one.
