Only the losing side is subject to war crimes trials, and no doubt rules of engagement will be developed and followed to prevent people going to jail due to “bad kills”.

There are really no “bad kills” in the armed services, there’s just limited exposure of public scandals.

Especially for the US who doesn’t subject its self to international courts like The Hague. So any atrocities, accidents, or war crimes will still just be internal scandals and temporary.

Same as it is today.
