"out of control drone attacks"? 
I would question your idea that the militaries spend huge sums to develop precision guided munitions and incredible surveillance capability and then just blast away at anything that moves. Not so. 
I would suggest that you see the recent movie "Eye In the Sky" to get a better idea of what's going on. I have read elsewhere that drone operators spend months to track the movements of an enemy individual to learn as much as possible about him before anyone even thinks about using any sort of lethal force.
