So how much of Sun Tzu’s work can we really consider relevant today, in a world where nearly all military conflict is multi-cultural, takes place within a global security environment with established rules of its own, and involves such elements as navies, air forces, ballistic missiles, and satellites? Or perhaps it’s silly to expect the writings of a military philosopher from the 6th Century B.C. to be appropriate today for anything other than understanding the military and political history of the region.
