Katyn forest...murdered 1500 Polish military officers. Hands tied behind backs, single shot to the back of the head by a 7.62 Tokarev or Makarov pistol. Kicked into a mass grave...like garbage.
The International Socialists (Russians) blamed the National Socialists (Nazis).
The National Socialists blamed the International Socialists.
However...the Germans weren’t in control of that area at the time of the murders.
The Russians were. Kinda sets it squarely on them.
The Soviet secret police even used previously purchased German pistols, just so the brass and bullets would be blamed on the Germans over time. Very evil.
