Peace demands the most heroic labor and the most difficult sacrifice. It demands greater heroism than war. It demands greater fidelity to the truth and a much more perfect purity of conscience.
Thomas Merton

There will one day spring from the brain of science a machine or force so fearful in its potentialities, so absolutely terrifying, that even man, the fighter, who will dare torture and death in order to inflict torture and death, will be appalled, and so abandon war forever.
Thomas A. Edison

War is war. The only good human being is a dead one.
George Orwell

War is a defeat for humanity.
Pope John Paul II

Humanity should question itself, once more, about the absurd and always unfair phenomenon of war, on whose stage of death and pain only remain standing the negotiating table that could and should have prevented it.
Pope John Paul II

War is peace. Freedom is slavery. Ignorance is strength.
George Orwell

Serious sport has nothing to do with fair play. It is bound up with hatred, jealousy, boastfulness, disregard of all rules and sadistic pleasure in witnessing violence. In other words, it is war minus the shooting.
George Orwell

Every war when it comes, or before it comes, is represented not as a war but as an act of self-defense against a homicidal maniac.
George Orwell

War against a foreign country only happens when the moneyed classes think they are going to profit from it.
George Orwell

Serious sport is war minus the shooting.
George Orwell

The essential act of war is destruction, not necessarily of human lives, but of the products of human labor.
George Orwell

War is a way of shattering to pieces... materials which might otherwise be used to make the masses too comfortable and... too intelligent.
George Orwell

There is hardly such a thing as a war in which it makes no difference who wins. Nearly always one side stands more of less for progress, the other side more or less for reaction.
George Orwell

War is evil, but it is often the lesser evil.
George Orwell

The quickest way of ending a war is to lose it.
George Orwell

Oceania was at war with Eurasia; therefore Oceania had always been at war with Eurasia.
George Orwell

There is no avoiding war; it can only be postponed to the advantage of others.
Niccolo Machiavelli

War should be the only study of a prince. He should consider peace only as a breathing-time, which gives him leisure to contrive, and furnishes as ability to execute, military plans.
Niccolo Machiavelli

War is just when it is necessary; arms are permissible when there is no hope except in arms.
Niccolo Machiavelli

Sometimes by losing a battle you find a new way to win the war.
Donald Trump
