Soldiers don't make war on soldiers. When the nation's at war, everyone's at war. And that is its purpose. The draft is God's idea. It distributes the risk and burden of injury and death evenly through all regions and social classes.
Leaders lead from the front.
Those who would commit soldiers into battle must share their risks. They invaded an already occupied land and systematically killed its inhabitants. And they did so at God's direction. Sometimes people become so wicked the only solution is to make war upon them. OK, so I mixed both questions together.
