Of course, war and the large military establishments are the greatest sources of violence in the world. Whether their purpose is defensive or offensive, these vast powerful organizations exist solely to kill human beings. We should think carefully about the reality of war. Most of us have been conditioned to regard military combat as exciting and glamorous – an opportunity for men to prove their competence and courage. Since armies are legal, we feel that war is acceptable; in general, nobody feels that war is criminal or that accepting it is criminal attitude. In fact, we have been brainwashed. War is neither glamorous nor attractive. It is monstrous. Its very nature is one of tragedy and suffering.
