“If we can use an H-bomb--and as you said it's no checker game; it's real, it's war and nobody is fooling around--isn't it sort of ridiculous to go crawling around in the weeds, throwing knives and maybe getting yourself killed . . . and even losing the war . . . when you've got a real weapon you can use to win? What's the point in a whole lot of men risking their lives with obsolete weapons when one professor type can do so much more just by pushing a button?'
Zim didn't answer at once, which wasn't like him at all. Then he said softly, 'Are you happy in the Infantry, Hendrick? You can resign, you know.'
Hendrick muttered something; Zim said, 'Speak up!'
I'm not itching to resign, sir. I'm going to sweat out my term.'
I see. Well, the question you asked is one that a sergeant isn't really qualified to answer . . . and one that you shouldn't ask me. You're supposed to know the answer before you join up. Or you should. Did your school have a course in History and Moral Philosophy?'
What? Sure--yes, sir.'
Then you've heard the answer. But I'll give you my own--unofficial--views on it. If you wanted to teach a baby a lesson, would you cuts its head off?'
Why . . . no, sir!'
Of course not. You'd paddle it. There can be circumstances when it's just as foolish to hit an enemy with an H-Bomb as it would be to spank a baby with an ax. War is not violence and killing, pure and simple; war is controlled violence, for a purpose. The purpose of war is to support your government's decisions by force. The purpose is never to kill the enemy just to be killing him . . . but to make him do what you want him to do. Not killing . . . but controlled and purposeful violence. But it's not your business or mine to decide the purpose of the control. It's never a soldier's business to decide when or where or how--or why--he fights; that belongs to the statesmen and the generals. The statesmen decide why and how much; the generals take it from there and tell us where and when and how. We supply the violence; other people--"older and wiser heads," as they say--supply the control. Which is as it should be. That's the best answer I can give you. If it doesn't satisfy you, I'll get you a chit to go talk to the regimental commander. If he can't convince you--then go home and be a civilian! Because in that case you will certainly never make a soldier.”
