CS Lewis on Pacifism

"It is arguable that a criminal can always be satisfactorily dealt with without the death penalty. It is certain that a whole nation cannot be prevented from taking what it wants except by war. It is almost equally certain that the absorption of certain societies by certain other societies is a great evil. The doctrine that war is always a greater evil seems to imply a materialist ethic, a belief that death and pain are the greatest evils. But I do not think they are. I think the suppression of a higher religion by a lower, of even a higher secular culture by a lower, a much greater evil . . . . The question is whether war is the greatest evil in the world, so that any state of affairs, which might result from submission, is certainly preferable. And I do not see any really cogent argument for this view."
