Okay, so to what end do you wish to employ this appeal to nuance? I ask because usually this is just a naive argument in favour of inaction. Of course inaction is an action in itself, with consequences that can be just as serious as those of actions. See e.g. Obama on Syria.

I don't quite see your point here. Russians were killing Ukrainian civilians in territory they attacked and occupied, and presumably this is still happening on the territory they still hold. I definitely count that as genocide, I don't see how this situation can be more nuanced.

OK, but in Ukraine, this is actually a genocide. Research it yourself, by any means, and see if you can come to any other conclusion.

It's the opposite of nuanced.
