Problem I see is the media and left have so well indoctrinated the normies at large that they won't believe anything Russia puts forward as evidence of crimes against humanity. They could show pictures and videos, and notes of research, starting from the hypothesis to the conclusion, following the experiments and logic, and people still won't believe it.
Most people in Germany had no clue about the crimes of the NSDAP until after the war either. At some point though they had no choice but to accept it. Most of them anyways.
