I guess my use of "a decisive battle" was a bit ambiguous. As you point out, Sun Tzu recommends either engaging in a battle you'll win decisively or not engaging at all. What I was referring to by "a decisive battle" was the supposed Western tradition of meeting up for one big battle to decide the war.Actually, by my interpretation of Sun Tzu, this is the heart of his wisdom. ALL battles of ALL levels are to be decisive and to your advantage, all others should be declined. Advantages should be maximized, weaknesses minimunized (And their appearances randomly mixed between truth and deception to confuse the enemy).
