The focus of modern war is causing physical harm to the enemy troops That's just so untrue. The focus of modern war is removing the enemy's will and ability to fight. One way, amongst many, to do that is to cause physical harm to people; it's an inefficient and difficult way that is massively dwarfed by far more competent and effective ways to wage a modern war. The focus of modern war is causing physical harm to the enemy troops, not merely destroying their capability for making war. You've got that the wrong way round. The focus of modern war is destroying their capability (and will) to fight.
