In order to successfully conduct espionage and sabotage, the
shinobi-whether a man or a woman-had to get close enough to the enemy
leader; and for that reason the shinobi had to be well-versed in
understanding human nature; assessing character; discovering personality
flaws; and surmising intentions. From there, the shinobi would proceed
to deceive, manipulates, exploit, and ultimately defeat the enemy; an
enemy who was not a simple robber, mugger, or criminal but rather
another warrior clan, an opposing fiefdom, an army from a neighboring
province. For this reason, fighting skill means little or nothing in the
larger context of the shinobi curriculum.
