None of the storyline actually takes place in 'Eurasia' or 'Eastasia' or any other part of the world. They don't need to even actually exist for the storyline.

It's not a prediction when it's history. That has been going on at least as long as the Roman Empire, yet people are still surprised it's happening today.
