“That there are men in all countries who get their living by war, and by keeping up the quarrels of Nations is as shocking as it is true…”

Source: The Sand Pebbles (1962), Ch. 5; speech of Lt. Collins
Context: It is said there will be no more war. We must pretend to believe that. But when war comes, it is we who will take the first shock and buy time with our lives. It is we who keep the faith. We are not honored for it. We are called mercenaries on the outposts of empire. … We serve the flag. The trade we follow is the give and take of death. It is for that purpose the American people maintain us. Any one of us who believes he has a job like any other, for which he draws a money wage, is a thief of the food he eats and a trespasser in the bunk in which he lies down to sleep!

Regarding the resolution of the Nullification Crisis, in a letter to Andrew I. Crawford (1 May 1833).
1830s
Context: Hemans gallows ought to be the fate of all such ambitious men who would involve their country in civil wars, and all the evils in its train that they might reign & ride on its whirlwinds & direct the Storm — The free people of these United States have spoken, and consigned these wicked demagogues to their proper doom.

Johnny Got His Gun (1938)
Context: Remember this well you people who plan for war. Remember this you patriots, you fierce ones, you spawners of hate, you inventors of slogans. Remember this as you have never remembered anything else in your lives. We are men of peace, we are men who work and we want no quarrel. But if you destroy our peace, if you take away our work, if you try to range us one against the other, we will know what to do. If you tell us to make the world safe for democracy we will take you seriously and by god and by Christ we will make it so. We will use the guns you force upon us, we will use them to defend our very lives, and the menace to our lives does not lie on the other side of a nomansland that was set apart without our consent it lies within our own boundaries here and now we have seen it and we know it.

Confessions of a Revolutionary (1849)
Context: It is necessary to have lived in this insulator which is called the national assembly, in order to perceive how the men who are the most completely ignorant of the state of the country are almost always the ones who represent it. I set myself to read everything that the distribution bureau sends the representatives: proposals, reports, brochures, even the Moniteur and the Bulletin of the laws. The greater part of my colleagues of the left and the extreme left were in the same perplexity of spirit, in the same ignorance of the daily facts. The national workshops were spoken of only with a kind of fright; for fear of the people is the defect of all those who belong to authority; the people, as concerns power, is the enemy.
