What is a war-crime? Modern far-right are not. Perhaps extremists. I am not getting into history and conspiracy. I am playing Devil's advocate. Neutral. I dont take sides. Until a hot war occurs then my nation is my side. Perhaps they've committed warcrimes in Donbass on any separatists. But to try warcrimes requires warcriminals to stand trial. It takes a war. Or a coup. Etc.

Would they false flag that population there? Not probable. Why, because any support, the calvary, isn't coming. It's suicide, not completely in their code. Any reaction outcry is the same, perhaps more or less, but the same. No Valkyries by suicide. Even they have some ethics. They hold out defending as soldiers to the last man. They've been using that city and population already, as a base of operations. Digging tunnels, fortifying, etc. The theatre was marked and more likely assumed it meant they could move in an out because it had other population in it.

I don't know, but I am running the odds. They don't favour the false flag there. Try it. Above.

We can debate existing strikes, and again the odds aren't in a favour of false flags. This is war. False flags start wars. They take attacks on the other sides supporting war or observing it. Not an existing war drawn into certain, uncertain preconditions.
