What is the theme in Strategy by B. H. Liddell Hart?

Another theme in this book is to simply educate the reader. The author makes the effort for the book to be enjoyable to read and does an excellent job of not assuming that the reader has much education in this subject already. Liddell Hart teaches the reader strategy by providing several chapters of simplified descriptions of wars. He covers centuries, gently introducing new concepts along with examples of different battles and nonviolent measures used as part of military strategy.
