IMO, it's often not even "war bad" but "fighting bad". Thus wanting the defender not to defend because that would be just as bad as attacking.
I consider myself a pacifist, so I prefer peaceful and diplomatic ways before going to war. But if you are attacked, you have the right, if not the duty, to defend yourself and your citizens.

If there was an animation, a flourish or some other visual marker it would help tremendously.
