March 17 2003 speech given by President Bush: "All the decades of deceit and cruelty have now reached an end. Saddam Hussein and his sons must leave Iraq within 48 hours. Their refusal to do so will result in military conflict, commenced at a time of our choosing. For their own safety, all foreign nationals -- including journalists and inspectors -- should leave Iraq immediately."
" Many Iraqis can hear me tonight in a translated radio broadcast, and I have a message for them. If we must begin a military campaign, it will be directed against the lawless men who rule your country and not against you. As our coalition takes away their power, we will deliver the food and medicine you need. We will tear down the apparatus of terror and we will help you to build a new Iraq that is prosperous and free."
"Should Saddam Hussein choose confrontation, the American people can know that every measure has been taken to avoid war, and every measure will be taken to win it. Americans understand the costs of conflict because we have paid them in the past. War has no certainty, except the certainty of sacrifice.
Yet, the only way to reduce the harm and duration of war is to apply the full force and might of our military, and we are prepared to do so."
"The cause of peace requires all free nations to recognize new and undeniable realities. In the 20th century, some chose to appease murderous dictators, whose threats were allowed to grow into genocide and global war. In this century, when evil men plot chemical, biological and nuclear terror, a policy of appeasement could bring destruction of a kind never before seen on this earth.
Terrorists and terror states do not reveal these threats with fair notice, in formal declarations -- and responding to such enemies only after they have struck first is not self-defense, it is suicide. The security of the world requires disarming Saddam Hussein now."
