Query: Excellent unless you are looking for Star Wars

This book is a highly cereberal study of history. I you want a lot of action look somewhere else. (I suggest David Drake or S.M. Sterling) If you want something to ponder this is the book. Asimov's ideas have been borrowed by other works so some of it will not seem new. The science is somewhat dated (nucleur light bulbs and economical transmutation). This book does give an excellent veiw of the forces of history. If you want to understand what causes nations to fall read this book. Just don't expect Star Wars style entertaiment.
