Colonel Barnett compares the next 15 years to the 15 years between World Wars I and II. He concludes that the changes between the two world wars may be dwarfed by those occurring within the next decade and one-half. He envisions possible wars with niche competitors and peer competitors, giving theoretical scenarios of each. Colonel Barnett views communications technology and stealth technology as keys to victory in future war. Colonel Jeffery R. Barnett, United States Air Force, is the Military Assistant to the Director, Net Assessment, Office of the Secretary of Defense. Foreword by Admiral William A. Owens, United States Navy, Vice Chairman, Joint Chiefs of Staff.
