War unhinges society, disturbs its peaceful and regular industry, and scatters poisonous seeds of disease and immorality, which continue to germinate and diffuse their baneful influence long after it has ceased. Dazzling by its glitter, pomp and pageantry, it begets a spirit of wild adventure and romantic enterprise, and often disqualifies those who embark in it, after their return from the bloody fields of battle, from engaging in the industrious and peaceful vocations of life.

War damages, the fabric of civilisation not by the destruction it causes (the net effect of a war may even be to increase the productive capacity of the world as a whole) nor even by the slaughter of human beings, but by the stimulated hatred and dishonesty.

In war, men lose what makes them great. Their creativity. Their wisdom. Their joy. All that's left is their utility. War is not monstrous for making corpses of men so much as it is for making machines of them. And woe to those who have no use in war except to feed the machines.

One certain effect of war is to diminish freedom of expression. Patriotism becomes the order of the day, and those who question the war are seen as traitors, to be silenced and imprisoned.

War is the health of the State. It automatically sets in motion throughout society those irresistible forces for uniformity, for passionate cooperation with the Government in coercing into obedience the minority groups and individuals which lack the larger herd sense. The machinery of government sets and enforces the drastic penalties. … [I]n general, the nation in wartime attains a uniformity of feeling, a hierarchy of values culminating at the undisputed apex of the State ideal, which could not possibly be produced through any other agency than war. Other values such as artistic creation, knowledge, reason, beauty, the enhancement of life, are instantly and almost unanimously sacrificed, and the significant classes who have constituted themselves the amateur agents of the State, are engaged not only in sacrificing these values for themselves but in coercing all other persons into sacrificing them.

The politicians' stirring phrases are meant to keep our eyes averted from the reality of war — to make us imagine heroic young men marching in parades, winning glorious battles, and bringing peace and democracy to the world. But war is something quite different from that. It is your children or your grandchildren dying before they're even fully adults, or being maimed or mentally scarred for life. It is your brothers and sisters being taught to kill other people — and to hate people who are just like themselves and who don't want to kill anyone either. It is your children seeing their buddies' limbs blown off their bodies. It is hundreds of thousands of human beings dying years before their time. It is millions of people separated forever from the ones they love. It is the destruction of homes for which people worked for decades. It is the end of careers that meant as much to others as your career means to you. It is the imposition of heavy taxes on you and on other Americans and on people in other countries — taxes that remain long after the war is over. It is the suppression of free speech and the jailing of people who criticize the government. It is the imposition of slavery by forcing young men to serve in the military. It is goading the public to hate foreign people and races — whether Arabs or Japanese or Cubans or Serbs. It is numbing our sensibilities to cruelties inflicted on foreigners. It is cheering at the news of enemy pilots killed in their planes, of young men blown to bits while trapped inside tanks, of sailors drowned at sea. Other tragedies inevitably trail in the wake of war. Politicians lie even more than usual. Secrecy and cover-ups become the rule rather than the exception. The press becomes even less reliable. War is genocide, torture, cruelty, propaganda, and slavery. War is the worst cruelty government can inflict upon its subjects. It makes every other political crime — corruption, bribery, favoritism, vote-buying, graft, dishonesty — seem petty.

It is in this way that a war is disastrous. If it does not kill, it transmits to some an energy alien to their own resources; to others it permits what the law forbids and accustoms them to short cuts. It artificially glorifies ingenuity, pity, daring. A whole younger generation believes itself to be sublime and collapses when it has to draw on itself for patriotism and fate.

Other curious and rather ominous consequences of war are the increased anti-Semitism which one meets in all classes, particularly the common people, and the strong recrudescence of anti-negro passions in the South. The first is due to the age-old dislike of a monied, influential and pushing minority, coupled with a special grudge against the Jews as being chiefly instrumental, in public opinion, in getting America into the war

Apart from the catastrophic sacrifices and material and human consequences, wars destroyed the future ethical norms and moral values of many generations. In years of many wars this territory was penetrated by a wave of deep and primordial hatred which in the rage of war destroyed human hearts and all human relations and certainly religious relations. For 45 years communism ploughed negative furrows in the souls of many people. It destroyed most of what not even World War II had erased. It destroyed the sense of the holy, the sacred, morals and honesty, the religious and ecclesiastical sense.

The world of today has achieved much, but for all its declared love for humanity, it has based itself far more on hatred and violence than on the virtues that make one human. War is the negation of truth and humanity. War may be unavoidable sometimes, but its progeny are terrible to contemplate. Not mere killing, for man must die, but the deliberate and persistent propagation of hatred and falsehood, which gradually become the normal habits of the people. It is dangerous and harmful to be guided in our life's course by hatreds and aversions, for they are wasteful of energy and limit and twist the mind and prevent it from perceiving truth.

wars are often the cause of further wars because they fuel deep hatreds, create situations of injustice and trample upon people's dignity and rights. Wars generally do not resolve the problems for which they are fought and therefore, in addition to causing horrendous damage, they prove ultimately futile. War is a defeat for humanity. Only in peace and through peace can respect for human dignity and its inalienable rights be guaranteed.

What a cruel thing is war: to separate and destroy families and friends, and mar the purest joys and happiness God has granted us in this world; to fill our hearts with hatred instead of love for our neighbors, and to devastate the fair face of this beautiful world.

But we find that war is followed by no general good whatever. The power, the glory, or the wealth of a very few may be enlarged. But the people in general, upon both sides, after all the sufferings are passed, pursue their ordinary occupations, with no difference from their former state. The evils therefore of war... are a mere loss without any advantage...

War makes men barbarous because, to take part in it, one must harden oneself against all regret, all appreciation of delicacy and sensitive values. One must live as if those values did not exist, and when the war is over one has lost the resilience to return to those values.
