From tonight’s speech:

On September the 11th, we learned that America must confront threats before they reach our shores – whether those threats come from terrorist networks or terrorist states. I am often asked why we are in Iraq when Saddam Hussein was not responsible for the Nine-Eleven attacks. The answer is that the regime of Saddam Hussein was a clear threat. My Administration, the Congress, and the United Nations saw the threat – and after Nine-Eleven, Saddam’s regime posed a risk that the world could not afford to take. The world is safer because Saddam Hussein is no longer in power. And now the challenge is to help the Iraqi people build a democracy that fulfills the dreams of the nearly 12 million Iraqis who came out to vote in free elections last December.
“Al Qaeda and other extremists from across the world have come to Iraq to stop the rise of a free society in the heart of the Middle East. They have joined the remnants of Saddam’s regime and other armed groups to foment sectarian violence and drive us out. Our enemies in Iraq are tough and they are committed – but so are Iraqi and Coalition forces. We are adapting to stay ahead of the enemy – and we are carrying out a clear plan to ensure that a democratic Iraq succeeds.
“We are training Iraqi troops so they can defend their nation. We are helping Iraq’s unity government grow in strength and serve its people. We will not leave until this work is done. Whatever mistakes have been made in Iraq, the worst mistake would be to think that if we pulled out, the terrorists would leave us alone. They will not leave us alone. They will follow us. The safety of America depends on the outcome of the battle in the streets of Baghdad. Osama Bin Laden calls this fight “the Third World War” – and he says that victory for the terrorists in Iraq will mean America’s “defeat and disgrace forever.” If we yield Iraq to men like Bin Laden, our enemies will be emboldened … they will gain a new safe haven … and they will use Iraq’s resources to fuel their extremist movement. We will not allow this to happen. America will stay in the fight. Iraq will be a free nation, and a strong ally in the war on terror. “We can be confident that our Coalition will succeed – because the Iraqi people have been steadfast in the face of unspeakable violence. And we can be confident in victory – because of the skill and resolve of America’s Armed Forces. Every one of our troops is a volunteer, and since the attacks of September the 11th, more than 1.6 million Americans have stepped forward to put on our Nation’s uniform. In Iraq, Afghanistan, and other fronts in the war on terror, the men and women of our military are making great sacrifices to keep us safe. Some have suffered terrible injuries – and nearly 3,000 have given their lives. America cherishes their memory. We pray for their families. And we will never back down from the work they have begun.
