“Active defense is also known as offensive defense, or defense by decisive battles. Passive defense is also known as purely defensive defense or pure defense. Passive defense is actually a sham defense; active defense is the only real defense, the only defense for the purpose of counter-attacking and taking the offensive. As far as I known, there is no military manual of any value, nor is there any reasonably intelligent military expert, ancient or modern, Chinese or foreign, that does not oppose passive defense, wether strategically or tactically. Only the greatest fool or madman would hold up passive defense as a magic weapon.”
