“Peace, gentlemen, it is well known, does not come of its own accord, and neither does freedom. Peace has enemies. Peace must be won by the sword.”

American Diplomacy (1951), World War I
Context: A democracy is peace-loving. It does not like to go to war. It is slow to rise to provocation. When it has once been provoked to the point where it must grasp the sword, it does not easily forgive its adversary for having produced this situation. The fact of the provocation then becomes itself the issue. Democracy fights in anger — it fights for the very reason that it was forced to go to war. It fights to punish the power that was rash enough and hostile enough to provoke it — to teach that power a lesson it will not forget, to prevent the thing from happening again. Such a war must be carried to the bitter end.
This is true enough, and, if nations could afford to operate in the moral climate of individual ethics, it would be understandable and acceptable. But I sometimes wonder whether in this respect a democracy is not uncomfortably similar to one of those prehistoric monsters with a body as long as this room and a brain the size of a pin: he lies there in his comfortable primeval mud and pays little attention to his environment; he is slow to wrath — in fact, you practically have to whack his tail off to make him aware that his interests are being disturbed; but, once he grasps this, he lays about him with such blind determination that he not only destroys his adversary but largely wrecks his native habitat. You wonder whether it would not have been wiser for him to have taken a little more interest in what was going on at an earlier date and to have seen whether he could have prevented some of these situations from arising instead of proceeding from an undiscriminating indifference to a holy wrath equally undiscriminating.
“It is vain, sir, to extenuate the matter. Gentlemen may cry, Peace, peace! But there is no peace.”
1770s, "Give me liberty, or give me death!" (1775)
Context: It is vain, sir, to extenuate the matter. Gentlemen may cry, Peace, peace! But there is no peace. The war is actually begun! The next gale that sweeps from the north will bring to our ears the clash of resounding arms! Our brethren are already in the field! Why stand we here idle? What is it that gentlemen wish? What would they have? Is life so dear or peace so sweet as to be purchased at the price of chains and slavery? Forbid it, Almighty God! I know not what course others may take; but as for me, give me liberty or give me death!

“[Peace must be] founded on truth, built according to justice, vivified and integrated by charity, and put into practice in freedom.”
[Pacem esse] dicimus in veritate positam, ad iustitiae praecepta constitutam, caritate altam et expletam, libertate postremo auspice effectam.
Pacem in Terris (11 April 1963), ¶ 167
