It is my conviction that killing under the cloak of war is nothing but an act of murder.

How long will it take the citizens of the United States, one wonders, to recognize that the house their country bombed in Iraq is the same one they were living in until it was foreclosed?

War is the business of barbarians.

When I first went to places where people were suffering from war and persecution, I felt ashamed of my feelings of sadness. I could see more possibilities in my life.

With those attacks, the terrorists and their supporters declared war on the United States. And war is what they got.

I have a scheme for stopping war. It’s this – no nation is allowed to enter a war till they have paid for the last one.

I have the conviction that excessive literary production is a social offence.

We all hoped in 2001 that we could put in place an Afghan government under President Karzai that would be able to control the country, make sure al-Qaeda didn’t come back, and make sure the Taliban wasn’t resurging. It didn’t work out.

We cannot be both the world’s leading champion of peace and the world’s leading supplier of the weapons of war.

World War II broke out in 1939, and many people credit that war with saving the economy.

It is not only the living who are killed in war.

The political object is the goal, war is the means of reaching it, and the means can never be considered in isolation from their purposes.

It is our duty still to endeavor to avoid war; but if it shall actually take place, no matter by whom brought on, we must defend ourselves. If our house be on fire, without inquiring whether it was fired from within or without, we must try to extinguish it.

Character is always known. Thefts never enrich; alms never impoverish; murder will speak out of stone walls.

The greatest destroyer of peace is abortion because if a mother can kill her own child, what is left for me to kill you and you to kill me? There is nothing between.

The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb. I developed a process for this purpose in 1900. It was perfected fourteen years later under the stress of war by German chemists.

War is so complex; human nature is so complex. There’s no filmmaker who has ever figured it out perfectly.

Politics is almost as exciting as war, and quite as dangerous. In war you can only be killed once, but in politics many times.

I saw what happened when a dictator was allowed to take over a piece of a country and the country went down the tubes. And I saw the opposite during the war when America joined the fight.

The Egyptians could run to Egypt, the Syrians into Syria. The only place we could run was into the sea, and before we did that we might as well fight.

War is regarded as nothing but the continuation of state policy with other means.

Mankind must put an end to war before war puts an end to mankind.

They wrote in the old days that it is sweet and fitting to die for one’s country. But in modern war, there is nothing sweet nor fitting in your dying. You will die like a dog for no good reason.

When the war of the giants is over the wars of the pygmies will begin.

Older men declare war. But it is the youth that must fight and die.

In war, events of importance are the result of trivial causes.

So long as governments set the example of killing their enemies, private individuals will occasionally kill theirs.

Those who can win a war well can rarely make a good peace and those who could make a good peace would never have won the war.

Peace is not the absence of war, but a virtue based on strength of character.

There is an afterlife. I am convinced of this.

For a war to be just three conditions are necessary – public authority, just cause, right motive.

Allow the president to invade a neighboring nation whenever he shall deem it necessary to repel an invasion,and you allow him to do so whenever he may choose to say he deems it necessary for such purpose – and you allow him to make war at pleasure.

A number of analysts have observed that although bin Laden was finally killed, he won some major successes in his war against the U.S.

Never think that war, no matter how necessary, nor how justified, is not a crime.

You say it is the good cause that hallows even war? I say unto you: it is the good war that hallows any cause.

I don’t oppose all wars. What I am opposed to is a dumb war. What I am opposed to is a rash war.

Communism is a religion that is inspired, directed and motivated by the Devil himself who has declared war against Almighty God.

Marriage is an adventure, like going to war.

When we are sick, we want an uncommon doctor; when we have a construction job to do, we want an uncommon engineer, and when we are at war, we want an uncommon general. It is only when we get into politics that we are satisfied with the common man.

Could I have but a line a century hence crediting a contribution to the advance of peace, I would yield every honor which has been accorded by war.

I am a little too absorbed by science to be able to philosophise much; but the more I look into myself, the more I find myself possessed by the conviction that it is only the science of Christ running through all things, that is to say true mystical science, that really matters. I let myself get caught up in the game when I geologise.

War is an instrument entirely inefficient toward redressing wrong; and multiplies, instead of indemnifying losses.

War is a poor chisel to carve out tomorrow.

It was times like these when I thought my father, who hated guns and had never been to any wars, was the bravest man who ever lived.

A war is a horrible thing, but it’s also a unifier of countries.

No body can be healthful without exercise, neither natural body nor politic, and certainly, to a kingdom or estate, a just and honourable war is the true exercise.

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

I can not believe that war is the best solution. No one won the last war, and no one will win the next war.

It is fatal to enter any war without the will to win it.

War is a contagion.

In the early days of the military Arpanet, my daughter was studying in Nicaragua. Because the U.S. was essentially at war with them, contact was difficult. I managed to use MIT’s Arpanet connection, and she found one, so we could communicate thanks to the Pentagon!

War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn how to live together in peace by killing each other’s children.

In 1962, war was avoided by Khrushchev’s willingness to accept Kennedy’s hegemonic demands.

But does that mean that war and violence are inevitable? I would argue not because we have also evolved this amazingly sophisticated intellect, and we are capable of controlling our innate behavior a lot of the time.

God is day and night, winter and summer, war and peace, surfeit and hunger.

We’ve persevered because of a belief we share with the Iraqi people – a belief that out of the ashes of war, a new beginning could be born in this cradle of civilization. Through this remarkable chapter in the history of the United States and Iraq, we have met our responsibility. Now, it’s time to turn the page.

Have we not come to such an impasse in the modern world that we must love our enemies – or else? The chain reaction of evil – hate begetting hate, wars producing more wars – must be broken, or else we shall be plunged into the dark abyss of annihilation.

War is the greatest plague that can afflict humanity, it destroys religion, it destroys states, it destroys families. Any scourge is preferable to it.

We must concentrate not merely on the negative expulsion of war but the postive affirmation of peace.

War is mainly a catalogue of blunders.

There is so much that must be done in a civilized barbarism like war.
