Hey, I'm not disagreeing (and don't worry, not offended ;)). When a terrorist launches an attack from inside a school or hospital, they are morally responsible for the damage incurred in the counter attack. No question in my mind.
If you're a marine, then you likely know first hand how modern insurgent tactics are steeped in hypocrisy. Attack from a crowd, next to a school etc and then use the resultant corpses in Youtube proproganda films. And because basic math seems to escape people, it works!
Gamma bombs, if they had functioned as desired, would help curb that while giving the US the moral high ground. And while no army should hesitate to kill their enemies, they should also be willing to take them alive if possible. Live prisoners give better intel, improve our image and undermine their ability to operate.
Though of course someone would bitch about the lost history, but can't win them all!
