And please don’t forget those who went through the „special camps“ in the Soviet zone from 1945 to 1950.
Of the roughly 160,000 internees, about 75% were Germans (most others were Soviet POWs who had been liberated at the end of hostilities, but who had somehow run afoul of the Soviet administration), many of whom were not affiliated with the Nazi party. About 40,000 perished in the camps, so I would not quite say that they were treated with kid- gloves…
The Soviets converted Buchenwald into an NKVD Concentration camp after the War.
