This song --for anyone who hasn't realized-- is directly about 1984. A book by George Orwell.
In it has three super states (Oceania, eurasia, and Eastasia) who are constantly at war in order for the leaders of these states to be forever controlled. Its all about power and brainwashing. George Orwell lived in the ages of the Great Wars where most of it is influenced by Stalin.
In the book they are ruled over by Big Brother(the figure head). Thier entire lives are restricted and watched.
This song is without a doubt, 100% 1984. Seriously. Not that's a bad thing but its just annoying to see people thinking its about Bush or Obama and how Muse made such deep lines when these are direct quotes from the Book. Go read it.
