Ever want to stop all the "wars of choice" the U.S. military keeps starting and getting us bogged down in? Then a new book, entitled Colonel Crystal’s Parallel Universe, 189 pages, (Trine Day, May 2019) may be for you. In the book, the lead character, decorated military officer, Col. Alva A. Crystal, USAF (ret.) decides there must be a better way to secure national defense for the United States than by taking on the world as imperialists since Alexander the Great have done, and devises a different, what he touts as a more suitable concept without all the persistent drawbacks that turn the world upside down and lead to constant worldwide turmoil and plots for revenge and avoidance, called a Defense-Only Military, similar to the prevailing military concept early in our history.
