I don't understand the people who protest drone strikes. War is hell - if your country engages in any sort of violent military intervention, there will be civilian casualties. I can get behind opposing unnecessary usage of military force; I can get behind opposing attacks within the borders of a sovereign nation that we aren't at war with. Protesting the tools used to conduct war instead of the war itself makes little sense to me, particularly when that tool marks a dramatic improvement in reducing civilian casualties.

Yes, if you look at drones-the-technology the protest looks a bit mistargeted. But that's just because it's a convenient label for drone-bombing-the-politics.
Compare nuclear weapons. You could say that they're just another increase in scale from the lethality of World war 2. But the politics (mutual assured destruction etc, antiproliferation etc) are different.
