But it wasn’t murder. Therein lies the issue. Collateral damage on military targets is war, and that is always been the scope of war. Limiting death to military personnel has always been unavoidable. Don’t start a war if you have a distaste of harm coming to your citizens. War has never been clinical.
Any nation invoking Divine Providence had better align itself with the Divine, less they be rebuked. Both Germany and Japan were rebuked. If you dig into the Nazis you will discover its leaders were deep into the occult. Japan’s mistaken beliefs are manifest.
Which Law’s of God are you invoking? The Deca Law? God gave the sword to government for a reason: to punish the wicked. Both Germany and Japan were wicked. Rulers are not a terror for good, but for evil, and they carry a sword to carry out God’s wrath (Romans 13:3-4).
If I launch a bomber raid on a munitions plant in an enemy country, the bombs that miss that munitions plant and kill innocents in the process are said to result in collateral damage. (This is the proper meaning of the word "collateral"; it is not intended.)
If I launch a bomber raid with the intent of simply destroying the city, then anyone and everyone in that city is an intended target; the deaths of the innocents are not collateral; the raid was designed to kill them.
(And it's not enough to say that just because we used sufficient firepower to kill the innocents, it doesn't mean that we actually wanted to kill them.)
Any nation invoking Divine Providence had better align itself with the Divine, less they be rebuked. Both Germany and Japan were rebuked. If you dig into the Nazis you will discover its leaders were deep into the occult. Japan’s mistaken beliefs are manifest.
And Communist Russia (who made both countries look like amateurs in their body counts)?
Your theology is terribly subjective, I'm afraid.
