re: #86 Sergey Romanov
Dunno. I remember Gerlach wrote a bit on that.
Am a wee bit familiar with Gerlach’s work.
I think it might have to do with the difference between Poland and USSR with respect to access for historians.
Also, I think it was due to the USSR not being interested in acknowledging that Jews had a special status in being persecuted in a way that was different from the average Soviet citizen. And finally, I also know that the USSR downplayed the number of the fatalities they suffered in WWII. Wasn’t it something like 10 million dead until Stalin died, and then 20 million until the fall of the USSR, while now it’s acknowledged to be around 27 million?
