I'm inclined to think the Russians would not have caused this one intentionally, although it is hard to imagine that Putin would have wanted to be involved in a Katyn commemoration ceremony.
There is no question that the Russians will now try to whitewash any possible fault they may have had in the plane repairs, etc.
But Putin was already involved in a Katyn commemoration ceremony with the polish prime minister Tusk on Wednesday, during which Putin did say publicly that Stalin’s regime was the perp in the Katyn massacre (the original one)
People, I’m really amazed at how little background you know about this thing.
Maybe not Katyn, I would say this is more like Palmiry, where the Nazis killed across the board the best and brightest of Poland, and not just officers.
