I just finished reading this book and I'm not sure if I'm understanding it correctly. The movie was nothing but critical of facism and militarism but this book seems to be a proponnent of a society in which all political power is held by those who have served in the armed forces and it seems as if there is no sarcasm or irony in the book. So is Heinlein's book really a proponent of an aristocratic oligarchy of the military class or am I just stupid?
