Clausewitz: It should be observed that the strategic defensive, though it is stronger than the offensive, should serve only to win the first important successes. If these are won and peace does not follow immediately, we can gain further successes only through the offensive. For if we remain continually on the defensive, we run the great risk of always waging war at our own expense. This no state can endure indefinitely. If it submits to the blows of its adversary without ever striking back, it will very likely become exhausted and succumb. We must begin, therefore, using the defensive, so as to end more successfully by the offensive.
