Reality is a lot murkier than theory. How are we to determine a state’s intent? Sometimes good intentions are bound up with bad; public justifications for war may not always represent the real reasons. And who is determine if a peace is just or a wrong has been committed? The nation initiating the war will use its own values to justify its intentions, and these values may be at odds with those of the other party to the conflict. Furthermore, it is altogether possible to fight a war for selfish motives and nevertheless protect civilians and reduce suffering in so doing.
