Well, Ukrainians don't think so, and then Russians of today have even more unambiguous genocidal intentions towards them. Paraphrasing a (Russian) classic – these genocides have never happened before and yet again.

Also, Wagners torture mobilized Russian soldiers just as gleefully as Ukrainian ones, but that does not mean that the genocidal intent is absolved, it just means that its the Russian way of doing things.
