The ethics of use of 'killer robots' is an extremely interesting discussion point. Is it right to send so called 'Killer Robots' to war on your behalf? and which country will be the 1st to give them the autonomy to act without Human sanction. More likely to occur 1st in Aerial Drones acting at break neck speed I would have thought but the ethics still apply.

I always understood that "War" had the aim of removing your enemy's ability to go against your aims and ambitions by either
a/ - Killing them
or
b/- proving to them that you could kill them and giving them the chance to give in.
In view of this sending Robot Killers to do your killing for you seems logical as it allows you to achieve your aims without risk to your population.
So - the first nation to deploy Robot Killers will probably be ... the first to develop them!
The ethics bit just seems to be - shall we allow our people to die when we can do the killing with no risk to our people?
I think that most mothers would think that sending their sons to fight or letting a Robot take the risk is a question that does not need asking.
The real ethical question is more - "should we be fighting this war?"
From the days of sharpened sticks as the "cutting edge of technology" to the present , anyone fighting a war, by definition, wants to win and will develop weapons that make it more likely that the home team will win with minimal losses to their population (a bit of a vote winner really!) - ethics seem to take a back seat or are dressed up versions of - "let us ban this as the other side might use it on us too" (as in poison gas).
As long as only one side has "The Super Weapon" military logic says "use it!"
