Wow, that is an insanely obtuse interpretation of what I said.

Of course there are always civilian casualties In war. Of course that is why war crimes exist in the first place.

"Massive" literally means "Large in comparison to what is typical". So when I say massive civilian cassualties forgive me for assuming you'd understand I was using that word for it's intended purpose.

Bombing a hospital full of civilians is absolutely a war crime.
