Robert A. Heinlein

" 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. "
" There are a dozen different ways of delivering destruction in impersonal wholesale, via ships and missiles of one sort or another, catastrophes so widespread, so unselective, that the war is over because that nation or planet has ceased to exist. What we do is entirely different. We make war as personal as a punch in the nose. We can be selective, applying precisely the required amount of pressure at the specified point at a designated time . . . .We are the boys who go to a particular place, at H-hour, occupy a designated terrain, stand on it, dig the enemy out of their holes, force them then and there to surrender or die. We're the bloody infantry, the doughboy, the duckfoot, the foot soldier who goes where the enemy is and takes him on in person. We've been doing it, with changes in weapons but very little change in our trade, at least since the time five thousand years ago when the foot sloggers of Sargon the Great forced the Sumerians to cry "Uncle!"Maybe they'll be able to do without us someday. Maybe some mad enius with myopia, a bulging forehead, and a cybernetic mind will devise a weapon that can go down a hole, pick out the opposition, adn force it to surrender or die--without killing that gang of your own people they've got imprisoned down there. I wouldn't know; I'm not a genius, I'm an M.I. In the meantime, until they build a machine to replace us, my mates can handle that job--and I might be some help on it, too. "
