President George W Bush has warned that a US withdrawal from Iraq could trigger the kind of upheaval seen after US forces left Vietnam. Here are key excerpts from his speech to war veterans in Missouri.
ON THE IRAQI PM
Prime Minister (Nouri) Maliki is a good guy - a good man, with a difficult job, and I support him.
ON THE CONSEQUENCES OF LEAVING IRAQ
To withdraw without getting the job done would be devastating. If we were to abandon the Iraqi people, the terrorists would be emboldened. They would use their victory to gain new recruits... Unlike in Vietnam, if we were to withdraw before the job was done, this enemy would follow us home.
ON THE CONSEQUENCES OF LEAVING VIETNAM
In Cambodia, the Khmer Rouge began a murderous rule in which hundreds of thousands of Cambodians died by starvation and torture and execution.
In Vietnam, former allies of the United States and government workers and intellectuals and businessmen were sent off to prison camps where tens of thousands perished.
ON PEARL HARBOUR
I want to open today's speech with a story that begins on a sunny morning, when thousands of Americans were murdered in a surprise attack. And our nation was propelled into a conflict that would take us to every corner of the globe.
A democratic Japan has brought peace and prosperity to its people. Its foreign trade and investment have helped jump-start the economies of others in the region. The alliance between our two nations is the linchpin for freedom and stability throughout the Pacific.
As one historian put it - he was talking about people criticising the efforts to help Japan realise the blessings of a free society - he said, had these erstwhile experts had their way, the very notion of inducing a democratic revolution would have died of ridicule at an early stage.
Without America's intervention during the war and our willingness to stick with the South Koreans after the war, millions of South Koreans would now be living under a brutal and repressive regime. The Soviets and Chinese communists would have learned the lesson that aggression pays.
ON THE MIDDLE EAST
Across the Middle East, millions of ordinary citizens are tired of war. They're tired of dictatorship and corruption. They're tired of despair. They want societies where they're treated with dignity and respect, where their children can have the hope for a better life.
