May I ask how old you are? I am serious here, not loaded question.
Thirty.
The number of Jewish victims of the Holocaust is commonly held as between 5,2 and 6,2 millions, see Hilberg, or Yehuda Bauer etc..
And i say: 3-6 millions. This means "3-6 millions from different sources". This does not deny the figures that you have brought.
And I will not discuss the topic which is the correct figure. I am not a historian and I have enough understanding of the overall level.
This does not negate the obvious: the Germans killed Soviet (including Jews, yes) more than anyone everything else.
Mortality of Soviet PoWs was "only" at pretty exactly 46%. The often quoted 57% number stems from Streit, Keine Kameraden... which contained a number of documented computing errors but keeps getting perpetuated in these sort of settings since people rarely take note of the more recent scholarship.
German PoW mortality was at 35% as of Maschke/WaST.
Italian PoW mortality, while difficult to precisely establish, for one was actually in excess of 50%.
Probably again different sources. In all Russian sources indicate that the Soviet prisoners of war was between 6 and 4.5 million (the second digit of the General Staff of the Armed Forces of the Russian Federation). Returned only 1,836,562 of them. For comparison.
Prisoners of war Germany's armed forces and allied countries it on April 22, 1956
Wehrmacht: 2,733,739 million.
Exemption: 2,352,671 million.
Died in captivity: 381,067
Germany's allies:
Total: 752,467
Exemption: 615,014
Died in captivity: 137,753
Well, this could delve into the realm of semantics, but just consider this, which I think illuminates the difference quite clearly: At the end of the day, Nazi Weltanschauung considered the Slavic peoples of the East a cow to be milked, a resource to be utilised, however ruthlessly.
As far as Leningrad is concerned, how does that contradict my point? The reasoning for letting the city starve was simple: Hitler in particular saw no military use in actually investing it, and believed the issue would "solve itself", saving Germany manpower and resources in the process.
Scored cow meat?
