Re: @ejit
So the unlawful killing is justified by the identification of the target. Whose identification? Under what judicial process was that determination made? While it may be convenient to use as your example a particularly nasty band of terrorist/freedom fighter - you pays your money, you makes your choice - The rather large Hellfire missile does not discriminate between jihadi and doctor tending the sick and innocent nearby.
When other nations acquire this technology and deploy it using their definition of terrorist are you going to so blithely cast aside the rule of law as you appear willing to do now, or is it only the size of the stick that counts?
