What metaphors are used in Mila 18 by Leon Uris?

Man's inhumanity to man is an underlying metaphor. As Von Epp stated to Chris De Monti, man is the only species that murders its own on a wholesale scale. According to him, this inhumanity is within man's basic nature, as evidenced by history. Since the beginning of time, conquest of one group by another has occurred without concern for destruction and devastation caused.
