I was thinking more about Politicians having a free hand to wage war as no is put at risk to do it.
But that's not how war works. People forget that war is not about killing the other side's military, robotic or no.
Those robot planes will still be bombing factories, towns, bridges, and cars full of people driving away from Baghdad International Airport. Terminators (if we make them) will still be standing in villages ready to burn crops and homes to the ground.
