Charles Stross wanders in a Britain of today in a world where Stalin won World War 2, taking all of western Europe into the control of the Soviet Union in the early 1940s:
Here’s a brief thought-experiment for you: imagine what the UK would look like today if the outcome of the second world war had taken a left turn early in 1940, and the whole of western Europe somehow ended up under Soviet control by 1946. (No nuclear weapons or gas attacks need apply: this speculation is about outcomes, not processes — so discussion of precisely how the British People’s Democratic Republic comes about is left as an exercise for the reader (and is not to be explored in comments)).
Let us further postulate that Stalinism passes with its creator, much as happened in our own experience of history: that the Soviet empire eventually undergoes the same fiscal crisis and collapse (alternative discussion of the same process by a former Soviet minister — you can forget the urban legend that Ronald Reagan did it) much as we remember, except possibly somewhat later — as late as the early 21st century, perhaps.
What interests me, in view of recent revelations about police spying and the extent of the British surveillance state is: How would the practice of internal suppression of dissent and state surveillance have differed in a post-Soviet Britain from what we appear to be living with right now?
“Whereof one cannot speak, thereof one must be silent”: as we have no way of knowing when the regime of the British Democratic People’s Republic fell, or what level of technology was available to them, purely technical aspects of the Communist surveillance state of the British Isles must be excluded.
However, we know the general shape of the ideological envelope within which Warsaw Pact regimes operated (or were allowed to operate, before the Kremlin jerked their choke-chain), and so we can speculate as to the structure and objectives of the British regime under Actually Existing Socialism.
