All warfare is based on deception. Hence, when we are about to attack, we must seem to have good faith peace talks; when using our forces, announce your plans; Make threats and deadline then change them; when we are near, we must make the enemy believe we are already there; when far away, mock our allies for having been foolish enough to participate in past failed wars we tricked them into. Always mock your allies.
— Don Tzu, The Art of the War
