US President George W Bush has made a rare address to the nation, to mark the five-year anniversary of the attacks of 11 September 2001.
Here are some key excerpts from his speech:
ON THE 'WAR ON TERROR'
It is a struggle for civilisation. We are fighting to maintain
the way of life enjoyed by free nations.
Mr Bush said the US was fighting to keep its way of life
We face a difficult road ahead. Winning this war will require the determined efforts of a unified country. So we must put aside our differences, and work together to meet the test that history has given us.
We face an enemy determined to bring death and suffering into our homes.
America did not ask for this war, and every American wishes it were over. So do I. But the war is not over, and it will not be over until either we or the extremists emerge victorious.
ON THE MIDDLE EAST
If we do not defeat these enemies now, we will leave our children to face a Middle East overrun by terrorist states and radical dictators armed with nuclear weapons. We are in a war that will set the course for this new century - and determine the
destiny of millions across the world.
And we are fighting for the possibility that good and decent people across the Middle East can raise up societies based on freedom, and tolerance, and personal dignity.
By standing with democratic leaders and reformers, by giving voice to the hopes of decent men and women, we are offering a path away from radicalism.
And we are enlisting the most powerful force
for peace and moderation in the Middle East: The desire of millions to be free.
I am often asked why we are in Iraq when Saddam Hussein was not responsible for the 9/11 attacks. The answer is that the regime of Saddam Hussein was a clear threat.
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.
ON BIN LADEN
Osama Bin Laden and other terrorists are still in hiding. Our message to them is clear: no matter how long it takes, America will find you and we will bring you to justice.
