Thomas Pynchon, Gravity's Rainbow page 645

The Germans-and-Japs story was only one, rather surrealistic version of the real War. The real War is always there. The dying tapers off now and then, but the War is still killing lots and lots of people. Only right now it is killing them in more subtle ways. Often in ways that are too complicated, even for us, at this level, to trace. But the right people are dying, just as they do when armies fight. The ones who stand up, in Basic, in the middle of the machine-gun pattern. The ones who do not have faith in their Sergeants. The ones who slip and show a moment's weakness to the Enemy. These are the ones the War cannot use, and so they die. The right ones survive. The others, it's said, even know they have a short life expectancy. But they persist in acting the way they do. Nobody knows why. Wouldn't it be nice if we could eliminate them completely? Then no one would have to be killed in the War.
