From a Russian point of view they choose to ignore Holdomor and of course preventing the Russians from “liberating” Prague by remnants of the German armed and uniformed Vlasoff’s Ukrainian army. They were fighting the Russians then the SS which they drove out surrendering the Czech capital to the Czech resistance. Thus keeping the Russians out temporairily. As their reward the Czechs gave the Ukrainians a death sentence by handing them over to the Russians.
Our hands aren't clean, neither.
