This was appalling and obviously sucked a lot for people who underwent such treatment; however as someone born in USSR I'd say that it was surprisingly humane (hot water not always available) compared to how people were treated in the USSR around the same period. Case in point: Ukrainian Holodomor (genocide by famine) http://www.rferl.org/a/holodomor-ukraine/25174454.html Edit: also, Chechen and Krimean Tatar deporta…
I can imagine a section in a future history textbook that went something like this:
"A distinctive feature of the Second World War was the widespread use of 'concentration camps'. These camps allowed belligerents to separate and control groups (usually racially defined) that were considered potentially subversive. In many cases, those interned were put to forced labor in support of the war effort, but in others they were simply kept under military control.
Conditions in these camps were generally poor, but they varied greatly both between and within countries. The Japanese in American concentration camps were subject to undernourishment and forced labor, but relatively few were killed. Things were worse in the Soviet Union, where even the process of transportation to the camps was deadly to large numbers of Volga Germans. The most infamous camps were in German-controlled territory, where millions of Jews and other undesirables were systematically executed, in an event later known as 'the Holocaust'."
