Query: One of the Top Sci-Fi Novels Ever

I have read this book probably 8+ times. It ranks up there as one of my favorites. Robert Heinlein not only is creative and well ahead of his time, he also shows that he's well read. If you've read any ancient history, you'll see that Heinlein bases his future society on the principles of Sparta. All "citizens" are soldiers, all soldiers fight, and education of the younger generation is done by veteran soldiers.I like Starship Troopers MUCH better than the Forever War by Joe Haldeman. Maybe because I get a kick out of Heinlein's conversative politics, rather than Haldeman's liberalism (I mean really, the soldiers of the future smoke grass and engage in nightly orgies?) Heinlein takes things back to basics-- capital punishment, public floggings, and NO LIBERAL WHINING! Read Starship Troopers.
