I would feel no hesitation in saying that it is the responsibility of a decent human being to give assistance to a child who is being attacked by a rabid dog, but I would not intend this to imply that in all imaginable circumstances one must, necessarily, act in accordance with this general responsibility. One can easily concoct imaginary situations in which it would be inadvisable, even immoral to do so [...] [I will not defend] the assumption that it is reprehensible for a powerful nation to invade a weak and tiny neighbor in order to impose on it an "acceptable" government [...] just as I would not take the trouble to justify my belief that one should assist a child being attacked by a rabid dog.
