I see this as the central issue of our time: how to find a substitute for war in human ingenuity, imagination, courage, sacrifice, patience.. War is not inevitable, however persistent it is, however long a history it has in human affairs. It does not come out of some instinctive human need. It is manufactured by political leaders, who then must make a tremendous effort--by enticement, by propaganda, by coercion--to mobilize a normally reluctant population to go to war.
What struck me as I began to study history was how nationalist fervor--inculcated from childhood on by pledges of allegiance, national anthems, flags waving and rhetoric blowing--permeated the educational systems of all countries, including our own. I wonder now how the foreign policies of the United States would look if we wiped out the national boundaries of the world, at least in our minds, and thought of all children everywhere as our own. Then we could never drop an atomic bomb on Hiroshima, or napalm on Vietnam, or wage war anywhere, because wars, especially in our time, are always wars against children, indeed our children.
