War is the province of chance. In no sphere of human activity is such a margin to be left for this intruder. It increases the uncertainty of every circumstance, and deranges the course of events.
The object of defense is preservation; and since it is easier to hold ground than to take it, defense is easier than attack. But defense has a passive purpose: preservation; and attack a positive one: conquest.... If defense is the stronger form of war, yet has a negative object, it follows that it should be used only so long as weakness compels, and be abandoned as soon as we are strong enough to pursue a positive object.
Interpretation
What this quote means
Defense focuses on preservation, while attack aims for conquest; the former is easier yet passive.
This quote by Carl Von Clausewitz emphasizes the strategic differences between defense and attack in warfare. He argues that while defense is essential for preservation and may be easier due to the advantage of holding ground, it is ultimately passive in nature. In contrast, attack is active and aimed at conquest, making it a positive objective. Therefore, defense should only be a temporary strategy, employed when circumstances require it, while one should seek to transition to a more assertive approach as strength increases.

But the main point is that soldiers, after fighting for some time, are apt to be like burned-out cinders. They have shot off their ammunition, their numbers have been diminished, their strength and their morale are drained, and possibly their courage has vanished as well. As an organic whole, quite apart from their loss in numbers, they are far from being what they were before the action; and thus the amount of reserves spent is an accurate measure on the loss of morale.
The more a general is accustomed to place heavy demands on his soldiers, the more he can depend on their response.
If the enemy is to be coerced, you must put him in a situation that is even more unpleasant than the sacrifice you call on him to make. The hardships of the situation must not be merely transient - at least not in appearance. Otherwise, the enemy would not give in, but would wait for things to improve.
In war, while everything is simple, even the simplest thing is difficult. Difficulties accumulate and produce frictions which no one can comprehend who has not seen war.

Until we go through it ourselves, until our people cower in the shelters of New York, Washington, Chicago, Los Angeles and elsewhere while the buildings collapse overhead and burst into flames, and dead bodies hurtle about and, when it is over for the day or the night, emerge in the rubble to find some of their dear ones mangled, their homes gone, their hospitals, churches, schools demolished - only after that gruesome experience will we realize what we are inflicting on the people of Indochina.
A war doesn’t merely kill off a few thousand or a few hundred thousand young men. It kills off something in a people that can never be brought back. And if a people goes through enough wars, pretty soon all that’s left is the brute, the creature that we—you and I and others like us—have brought up from the slime.
I think that this is the first war in history that on the morrow the victors sued for peace and the vanquished called for unconditional surrender.
These are they whose youth was violently severed by war and death; a word on the telephone, a scribbled line on paper, and their future ceased. They have built up their lives again, but their safety is not absolute, their fortress not impregnable.
I think a lot of people, including me, clammed up when a civilian asked about battle, about war. It was fashionable. One of the most impressive ways to tell your war story is to refuse to tell it, you know. Civilians would then have to imagine all kinds of deeds of derring-do.
It is important to emphasize that guerrilla warfare is a war of the masses, a war of the people. The guerrilla band is an armed nucleus, the fighting vanguard of the people. It draws its great force from the mass of the people themselves.
