And then I explained to him how naïve we were, that the
 world did know and remain silent. And that is why I swore
 never to be silent whenever and wherever human beings
 endure suffering and humiliation. We must always take
 sides. Neutrality helps the oppressor, never the victim.
 Silence encourages the tormentor, never the tormented.
 Sometimes we must interfere. When human lives are
 endangered, when human dignity is in jeopardy, national
 borders and sensitivities become irrelevant. Wherever men
 and women are persecuted because of their race, religion,
 or political views, that place must
 at that moment
 become the center of the universe.
 Elie Wiesel, Nobel Prize acceptance speech, 1986
