So if i can't prove any evidence does that mean Joseph is exhonerated from genocide and nominated for a post-humos nobel peace prize?
Wouldn't be the first time that's happened.
Typical allied puppet show.
If you do some research on STalin's intense dislike towards Poles from the Polish-Soviet war 1919-1920, and an order given by our nobel nominee in 1940 following the katyn massacre, you will be well on the way to getting your proof.
Polish reverse Officers, ethnic Poles, deportations, also google Lavrenty Beria.
Sorry to say but Stalin isn't going to become innocent. As much as some wish it.
