Moral war-making

Military honor lets the adversaries concede to each other moral equivalence. 

When conflict is moral rather than honorable, the adversaries must view each other as immoral, which leads to more vicious and fierce and unforgiving military handling of the enemy, whether of innocent civilian non-combatants or of war prisoners. 

Moral war-making invites massive propaganda campaigns to retain the moral fervor of the populace and to preserve the impression of the moral weakness of the adversary. It also opens the door for the persecution of fifth-columnists who do not share the moral zeal of the war-makers.
