With the indiscriminate nature of modern military technology (no such thing as a "smart bomb," it turns out) all wars are wars against civilians, and are therefore inherently immoral. This is true even when a war is considered "just," because it is fought against a tyrant, against an aggressor, to correct a stolen boundary.
