Yes, the Germans committed terrible atrocities against the Russians, Belarussians, Ukrainians, Jews & others in their invasion of the USSR. They were taught that Slavs - especially Russians, as well as Jews & Roma, were subhuman.
1 out of every 3 citizens of Belarus died in WW2 during the occupation. Tens of millions of Red Army POWs were murdered or starved to death by the Germans; tens of millions of Soviet citizens were taken as slave labour & many died during their slavery; thousands of villages & towns were burnt & the occupants massacred or left to fend for themselves with no food or shelter. The atrocities led by the Einsatzgruppe are infamous - Babi Yar, Slonim, Berdichev, Odessa, Maly Trostenets etc etc.
BUT Karma is right in that Stalin & his regime were as evil as Hitler's; & that he caused the deaths of tens of millions of people.
Stalin's regime did not sit down & coldly create death factories like Treblinka, Belzec, Birkenau, Chelmno, Sobibor & Majdanek - the details of the burning pits, gas vans, bone crushing machines, crematoria & gas chambers being constantly improved upon by technicians & engineers to increase their killing capacity.
I think that is what stands out about the Holocaust: that the Nazis employed people to scientifically plan for the extermination of a race in such a rational & calculating manner.
But the USSR had the endless Gulag - work camps where millions of people were exiled & many died from exhaustion, cold, industrial accidents & disease. Millions more were shot by the NKVD or deliberately starved (as in 1930s Ukraine). Whole populations were deported thousands of miles where they were left to struggle to build new lives with minimal resources. They were declared 'enemies of the state' as Stalin wished - due to their nationality, ethnicity, religion, political views or social class.
Comparing the numbers of deaths is pointless - Stalin's regime survived far longer than Hitler's so it's inevitable that more died as a result of Stalin's policies.
As far as is known - the USSR had no Treblinkas complete with gas chambers; & many people survived the Gulag & their exile to return home when Stalin died or to leave the USSR.
The atrocities committed by the Germans (who pretended to be allies to the USSR until Operation Barbarossa) shocked even the most hardened Red Army soldiers. They did not understand why the Germans - who they had not regarded as enemies before - had thought of them as less than human & wanted them all dead or enslaved.
So those whose families had lived in the occupied areas had good reason to hate the Germans intensely.
But the evidence is that Red Army soldiers raped any women & girls they found - Polish, Jewish camp survivors, Hungarian, even Russian women liberated from slavery; as well as German women. The harsh fact is that the men of the Red Army were allowed to do exactly as they wanted in the areas they liberated or occupied - just as the German army had.
The sad & horrible truth is that tens of thousands of 'minor' Nazi war criminals received light sentences or escaped punishment.
Yet German women & children who themselves did not commit war crimes were raped by often drunk, undisciplined soldiers who used the German occupation of part of the USSR as an excuse to hurt them - & that is inexcusable.
On a lighter note - because that is all very depressing stuff - wonder what gems the Daily Mail has come up with today??
Maybe best not to look - it's like a car crash - you know you shouldn't read it but you can't help it.....!
