@SuperSnekFriend >War is always dysgenic and economically destructive, and wanting war without morally justified cause is un-Christian and evil. A truly effective and Christian leader cannot have a war-loving mind.
War is not bad, sometimes it's good to have it just to fuel your need for expansion. Just as Clausewitz said, war is just another tool in diplomacy. And in this case it's justified, by destroying the foreign invaders and keeping the nation clean.
