Soviet troops retreating were machine gunned down by NKVD squads.
I'm reminded of the picture original published in a Soviet encyclopedia. It showed five Russian fighters standing on a hill in winter, smiling after victory.
Years later, when one of the men fell out of Soviet favor (and out of sight), the encyclopedia publisher sent out the annual "updates". Recipients were to paste the updated data over the old. One included a picture of the men, still standing on the hill-side. In this "update" there were only four men, the man in the middle having been conveniently "removed" with a marginally clever touch-up.
""Stalin made very tough orders concerning the treatment of German civilians"
The BIG LIE is often more effective than a small one. This sounds like DPRK propaganda.
"We lost 27 million people, and each had five liters of blood."
They still don't get that most of them were (directly or not) killed by the uncle.
Gee maybe if Stalin didn't cozy up to Hitler to invade Poland in the first place, maybe the Soviets wouldn't have lost that many.
Sad that these "historians" dont show the same amount of hostility with Stalin, who killed more Russians under his command than the Nazi's did in battle, than they do with the Nazis.
Remember that only party members got notification.
The ratio is probably 1:2 Stalin.
The Soviet Union suffered a million casualties in the Winter War, when they invaded Finland without provocation, before the start of the war with Hitler.
WWII started when it did because Stalin entered into a secret pact with Hitler to carve up Poland. That gave Hitler the insurance he needed to launch the Blitzkreig. So who started WWII (or as the Soviet propagandists called it, "The Great Patriotic War")? Stalin - the great Soviet leader/butcher/murderer.
