Re: I hope for more traditional space battles
What we talking about here is whether Kirk should have just gotten his butt out of Dodge, or waste time petulantly contributing his relatively impotent efforts to the inevitable demise of a defenceless foe. Neither choice is heroic, but I can't see how having Kirk commit a war crime was the way to go.
I'm not sure how something really counts as a "war crime" if those killed were faced with imminent "inevitable demise" anyway.
Just walk away, and there will be an end to the horror.
