Before invading another country we send our spies in. They infiltrate the nerve centers without being noticed. At the time of full scale attack they cut the supply lines and destroy the electrical power stations. Caught off-guard the enemy rush to their battle stations only to be picked off one after one. Without their essential power supply they loose all their counter force and are easily overrun. Without any delay we occupy the main crossroads and key locations, hold the high ground and send our spies even further ahead, to infiltrate the very heart of resistance. Without firing even one shot we flood the enemy land with our own forces, occupying it to squeeze out any remaining opposition. In one well planned and well executed strike we manage to neutralize and overtake our opponent without much loss on either side.
I'm guessing this isn't a prescription for war so much as a metaphor for how we might project our ki/intent into our would-be attackers, maximizing utility?
