It's interesting to note that Sun Tzu's main keys to success were positioning and deception, rather than completely focusing on long elaborate plans.  I think it is actually a smart way of getting what you want, because essentially cleverness and wit may outsmart the enemy leading to their careless, unfortunate defeat. 

I believe that it is important to preserve for future generations, because of its influence on the military minds today.  Without the deception, the military would not have gotten as far as it has today with equipment or men.

Were there any illustrations in this book?
