Ah, forgot those "islands" However, life for a devoted commie wouldn't have to be that bad, while the life for a suspected commie in the USA in the times of McCarthy would not be too good. No Gulag though.
BTW, recently "visited" the former STASI hq in Dresden.
It was a house belonging to the great-granparents of my wife. A house in a nice neighbourhood, sited in the slopes above the Elbe, facing the core of Dresden.
Anyway, a whole row of houses (5 or so) belonged to the Stasi, with the USSR service (Putin they said) on the other side of the street.
The houses had been connected with a network of tunnels, so that basically Stasi personnel never walked the streets much on errands.
They were well fenced off with double fences and dogs between them. The barbed wire tilted INWARDS though!
There were movement sensors and floodlights, and the slope down to the Elbe (It's some piece of land) is covered with thorned scrub, - You will do some shredding if you try crossing there.
After the wall fell, and Stasi went under, the house has been abandoned. However, the awe was such that it was untouched for some 10 years. It now belongs to the former owners.
Imagine, all that Stasi stuff just in that city. Incredible!
