Yup, Van Creveld actually is one of the more prominent military historians and authors out there. Hard to avoid him if you read about modern strategy, and he's cited by everyone.
Just for fun, I checked and hes still on Chairman Joint Chiefs of Staff Recommended Reading Lists, Marine Corps Commandant Recommended Reading Lists, and Professional Reading: US Army Course Credits with titles like Airpower and Maneuver Warfare, Command in War Supplying War: Logistics from Wallenstein to Patton, not his historical work. Really not someone whose opinion should be discarded. I'd prefer receiving the message of the article from someone else.
