"5.) BELARUS per capita lost more than Ukraine and Russia during WWII. "
Perhaps true but I doubt it. Ukraine is in between Berlin and Stalingrad - not Belorus.
But I would not be surprised - the Kremlin is still trying to crush them.
Yes, Belarus per capita was the worst hit in the SU. As I recall, the Red Partisans were the most active there, and Germans held reprisals against the population. Like in Ukraine, the front moved through Belarus twice.
