The Legal and Ethical Limits of Technological Warfare
I didn't attend the symposium, so I don't know if they concluded whether or not there are limits, legal or technological, to warfare. However, I have been thinking about this in the interval.
I concluded at the time that for the US, there really are no limits. Now, listen carefully so you don't misunderstand. I think that the US feddle gummint believes that there are no limits to how it conducts warfare.
I further think that the US passed the ethical limits of technological warfare long ago, perhaps on a certain few days in August, 7 decades ago, perhaps earlier.
If anyone doubts the messianic character and grasping of the feddle gummint, one only has to see the assumed omniscience and omnipotence of the drone wars being conducted around the world by the US.
Here is a little wisdom from the actual source, "Vengeance is mine; I will repay, saith the Lord." (Romans 12:19)
