I like the comparison to Orwell's 1984 more than anything. Efrafa and General Woundwort aren't precisely analogous to any particular dictatorship or police state, though, you can make comparisons to Nazi Germany or the Soviet Union or however many other totalitarian setups. It's a nightmare, a theoretical, cautionary, and timeless take on a society gone horribly awry. A tale of what happens when you give up too much of your freedom and independent thought in exchange for ultimately frivolous safety out of fear.
The fact that you can make a really close comparison with North Korea now just shows that Efrafa is still a very relevant idea to be reading about. That's what I think matters.
Now this has me thinking about the Warren of the Shining Wires and how they'd fit in to this kind of analogy. Something more focused on giving up cultural identity, perhaps. Just something to ponder.
