This, for some reason, remind me about Katyn massacre.
Right, the Katyn massacre. I'm not trying to open a debate about it here, as it's still very much an on going debate between historians and politicians. But, it seems there was no "Katyn massacre", as in "Soviet Union never had a hand in such an event". I'm just saying this because right now, the ones trying to disprove all the accusasion of "Soviet Union did it" and "Russia admitted the event to be true" are having the upper hands in the debate, seeing how all the published archives were dis-credited by the people it mentions by name.
On the other hands, in 2012, a Polish archeologist team, through investigation concluded that there indeed was a "Katyn massacre". They even took pictures as proof. Only that, their conclusion was that the Germans were the culprits.
So yeah. It's a very complicated matter and very much unlike what we are seeing above. The above is easy to understand. "Katyn" though.... I don't think it's anywhere near easy to understand.
