From that same page which by the way that number was total deaths on both sides
POP Mil. dths Civ dths total deaths
China[9] 530,000,000 3,000,000 7,000,000 10,000,000
Somehow I don't think the Germans were responsible for any of these.

Soviet Union[49] 168,500,000 10,700,000 11,500,000 1,000,000 23,200,000
and the total holocaust deaths listed is 5,754,000 not 25 million. However I would not claim these numbers are definitive.
As far as Stalin's count goes that too is subject to debate by people who know more than me.
About the only thing that any of this has to do with today's vote is nothing.
