Mostly Russians though, and this was the case under the Russian Empire which included all those groups too.
Well you can believe what you want, and I'm sure you will, but the facts are clear. Stalin had decimated his army with unrelenting purges, and that is why Hitler thought he was an easy mark. That's why Hitler invaded Russia (i.e. Soviet Union). And per my previous references, Stalin did believe the pact would hold. But Stalin's distrust of the British led him to ignore their warnings in the belief that they were a trick designed to bring the Soviet Union into the war on their side.[92] He had an ill-founded confidence in the Molotov–Ribbentrop Pact [/B]and suspected the British of trying to spread false rumours in order to trigger a war between Germany and the USSR.[93] In early 1941, Stalin's own intelligence services and American intelligence gave regular and repeated warnings of an impending German attack.[94] Soviet spy Richard Sorge also gave Stalin the exact German launch date, but Sorge and other informers had previously given different invasion dates that passed peacefully before the actual invasion.[95] Stalin acknowledged the possibility of an attack in general and therefore made significant preparations, but decided not to run the risk of provoking Hitler. https://en.wikipedia.org/wiki/Operation_Barbarossa#Soviet_preparations
You have a right to your opinion, but Soviet troop positioning leads to a more logical conclusion that Russia was caught of guard because it was getting ready for her own offensive.
Give advice, please. What was supposed to do in that situation, Stalin? Chronicle .1938 1 ... England France gave the Sudetenland (Czechoslovakia line of defense) for Hitler. . . 2 ... Poles and Hitler divided Czechoslovakia residues. . . All are friendly with Hitler. Stalin to be the best? The most kind, gentle, white and fluffy? .It's not personal. It's strictly facts.
