My Grandmother lost a couple of brothers to Stalin. She, her husband and their first-born came to the US in 1904, knowing what was coming. Her brothers were in an elite regiment in the Russian Army (they were among the Czar's bodyguards, from what I was told) and stayed in Russia. They were in contact until the late 20s, and then silence. They were the sons of a land-owning farmer, ethnic Germans and from the Ukraine. Did they die in the Solovetsky Islands? A dank, obscure basement? Working on the Belomor Canal? The Kolyma gold field camps? The Vorkuta timber cutting camps? The Ukrainian terror famine? I'll almost certainly never know. That was some 25 years before I was born and didn't touch me personally. But I won't forget that Stalin was one of the worst monsters so far in human history, in the same league as Mao, Hitler and Lenin.
For some reason, Russia hasn't seen fit, that I've heard, to open a large-scale Gulag memorial at the Belomor Canal (Kolyma, Vorkuta and the Solovetsky Islands being rather remote, the lack of a memorial would make sense even if the will were there). Between that lack of a public revelation/reminder and Vlad the Impaler II, I would not be surprised if Russian repression reached Leninist-Stalinist scale in 10 or 20 years.
