When I was bombing cities in Germany, Hungary, Czechoslovakia, and France in the Second World War, the moral justification was so simple and clear as to be beyond discussion: We were saving the world from the evil of fascism. I was therefore startled to hear from a gunner on another crew -- what we had in common was that we both read books -- that he considered this "an imperialist war." Both sides, he said, were motivated by ambitions of control and conquest. We argued without resolving the issue. Ironically, tragically, not long after our discussion, this fellow was shot down and killed on a mission.
