Sure it would be called those things and then nothing would come of it. If a country uses morally compromised methods to win a war history just calls it winning the war.

The winners write the history books

That seems to be changing. I've seen an uptick in criticism against the usa for unnecessarily (according to top military advisors, experts, generals etc at the time) dropping the atom bomb on Japan for example.

Wouldn't stop anyone from doing it again if the stakes were high enough

Absolutely. The bombing of Dresden has been viewed as a mistake - verging on a war crime - in Britain for the last 20 or so years.

By some people - that's certainly not a universal view.

Verging on? It was a mass murder of civilians. The US holocausted Japan and got away with it.

And Japan did similar levels of atrocities to Korea, China, and others in the region.

We can acknowledge that things were historically pretty horrible and strive to be better in the future.

You kidding? What do you think a business loan is? Almost every business needs some form of subsidy to get off the ground.
