"Because of American leadership and resolve, the world is changing for the better. Last month, the leader of Libya voluntarily pledged to disclose and dismantle all of his regime's weapons of mass destruction programs, including a uranium enrichment project for nuclear weapons. Colonel Qadhafi correctly judged that his country would be better off, and far more secure, without weapons of mass murder. Nine months of intense negotiations involving the United States and Great Britain succeeded with Libya, while 12 years of diplomacy with Iraq did not. And one reason is clear: For diplomacy to be effective, words must be credible -- and no one can now doubt the word of America."
