Yes I am aware, and I didn't meant to equate the bombing of Serbia with Russia's invasion of Ukraine if you understood it this way.

I simply meant it as an example were NATO as an "entity" arguably broke international law. I say "arguably" because there is some debate about this.

I think this is a clear case where war is just very messy. It is easy to come up will all kinds of legal frameworks during peace time. And then a war situation will not be what you expect.
