It's called "the fog of war" for a damn good reason--war is at best an imprecise and muddled business. Decisions are made on the basis of imperfect knowledge and imperfect understanding. There is a great deal of guesswork in war. Thus it is the "art" of war and not the "science" of war.
We will not have "clarity" in the conduct of war--not today, and most assuredly not tomorrow. We should not be offended at the lack of clarity from yesterday.
The only real "war crime" is losing. Everything after that is a question of how much carnage can you stomach.
