Read this excerpt from the conclusion of Elie Wiesel's "The Perils of Indifference" speech:

"Does it mean that we have learned from the past? Does it mean that society has changed? Has the human being become less indifferent and more human? Have we really learned from our experiences? Are we less insensitive to the plight of victims of ethnic cleansing and other forms of injustices in places near and far? Is today's justified intervention in Kosovo, led by you, Mr. President, a lasting warning that never again will the deportation, the terrorization of children and their parents, be allowed anywhere in the world? Will it discourage other dictators in other lands to do the same?"
