Well current government of russian federation is trying to whitewash the facts and alter history history as always. I mean they even have their own name for the war - The “great patriotic war” to hide the fact they’ve been allies with Hitler between 1939 and 1941, so I think it’s quite important to remind them of that. Just look at r/pikabu dweebs downvoting away at a simple historical truth.

And

There are documented instances of soviet squads dressed as Ukrainian freedom fighters during WWII committing warcrimes against civilian population, Poles and Jews to rob them of support from the populace. Good thing about these kind of affairs is that if they get captured they don't get the benefits of Geneva convention.
