A world in “1984” is a place under totalitarian regime and surveillance of small oligarchic groups who control all the economic leverages. There are iconic idols as, i.e. mysterious Big Brother who is watching you from any corner from the posters, TV and etc. People live in the realm of lies, have lost even the freedom of thought and every backslider is quickly found and recharged in the Ministry of “Love”.
"This book is a magnified projection into the future of a present that contained Stalinism and an immediate past that had witnessed the flowering of Nazism...In the context of 1948, 1984 seemed dreadfully convincing. But tyrants, after all, are mortal and circumstances change...it now looks as though the odds were more in favor of something like Brave New World than of something like 1984. The society described in 1984 is a society controlled almost exclusively by punishment and the fear of punishment - it is less effective in the long run than reinforcement of desirable behavior, non-violent manipulation, both physical and psychological, and by genetic standardization" (A. Huxley, 1958). Though, the book wasn't prophetic for the world in 1984, many experts claim that it is still very convincing and prophetic for Russia and its political system. Orwell had been a communist before he visited Soviet Russia and saw the brutality of Stalin regime - the book was partly inspired by Russia.
