A subset of the Sun Tzu example is the view that war is deception. In this subset, the attempt is to deceive the enemy into what we wish the enemy to perceive and thereby trick, cajole, induce, or force the adversary. The thrust or target is the perception, understanding, and knowledge of the adversary. In some ways, the ancient Trojan Horse is an early example of deception. However, as we will see, the deception model may have new foundations in the technological innovations that are occurring and in our ability to control the environment.
