"What scares me about drone strikes is how they are perceived around the world," [retired General Stanley McChrystal] said in an interview. "The resentment created by American use of unmanned strikes ... is much greater than the average American appreciates. They are hated on a visceral level, even by people who've never seen one or seen the effects of one."
Oddly, Obama Democrats used to feel the same way, at least until their guy was pushing the button (in fact, pushing the button far more frequently than Bush did). We are overusing this tool.
