Question: Who tops your reading list?
General Mattis: Colin Gray from the University of Reading is the most near-faultless strategist alive. Then there’s Sir Hew Strachan from Oxford, and Williamson Murray, the American. Those three are probably the leading present-day military theorists. You’ve got to know Sun-tzu and Carl von Clausewitz, of course. The Army was always big on Clausewitz, the Prussian; the Navy on Alfred Thayer Mahan, the American; and the Air Force on Giulio Douhet, the Italian. But the Marine Corps has always been more Eastern-oriented. I am much more comfortable with Sun-tzu and his approach to warfare.
