The Tartars fought with Hitler against the Russians. Stalin deported them en masse as a collective punishment.
That can be condemned.
However the Tartars were silent or even helped the fascist round up millions of Ukrainian Jews.
Perhaps a more fitting song would be to apologise to the survivors of the fascist horror.
Oh wait, it may be claimed by these "victims" that no Jew was harmed.
Eurovision is a Pacifist-fest which reflects the weakness of European politics.
