President Barack Obama's speech on Iraq

WASHINGTON (Reuters) - Following is the text, as prepared for delivery, of President Barack Obama's speech on Tuesday on Iraq.

"Good evening. Tonight, I'd like to talk to you about the end of our combat mission in Iraq, the ongoing security challenges we face, and the need to rebuild our nation here at home.

"I know this historic moment comes at a time of great uncertainty for many Americans. We have now been through nearly a decade of war. We have endured a long and painful recession. And sometimes in the midst of these storms, the future that we are trying to build for our nation - a future of lasting peace and long-term prosperity may seem beyond our reach.

"But this milestone should serve as a reminder to all Americans that the future is ours to shape if we move forward with confidence and commitment. It should also serve as a message to the world that the United States of America intends to sustain and strengthen our leadership in this young century.

"From this desk, seven and a half years ago, President Bush announced the beginning of military operations in Iraq. Much has changed since that night. A war to disarm a state became a fight against an insurgency. Terrorism and sectarian warfare threatened to tear Iraq apart. Thousands of Americans gave their lives; tens of thousands have been wounded. Our relations abroad were strained. Our unity at home was tested.

"These are the rough waters encountered during the course of one of America's longest wars. Yet there has been one constant amidst those shifting tides. At every turn, America's men and women in uniform have served with courage and resolve. As Commander-in-Chief, I am proud of their service. Like all Americans, I am awed by their sacrifice, and by the sacrifices of their families.

"The Americans who have served in Iraq completed every mission they were given. They defeated a regime that had terrorized its people. Together with Iraqis and coalition partners who made huge sacrifices of their own, our troops fought block by block to help Iraq seize the chance for a better future. They shifted tactics to protect the Iraqi people; trained Iraqi Security Forces; and took out terrorist leaders. Because of our troops and civilians - and because of the resilience of the Iraqi people - Iraq has the opportunity to embrace a new destiny, even though many challenges remain.

"So tonight, I am announcing that the American combat mission in Iraq has ended. Operation Iraqi Freedom is over, and the Iraqi people now have lead responsibility for the security of their country.

"This was my pledge to the American people as a candidate for this office. Last February, I announced a plan that would bring our combat brigades out of Iraq, while redoubling our efforts to strengthen Iraq's Security Forces and support its government and people. That is what we have done. We have removed nearly 100,000 U.S. troops from Iraq. We have closed or transferred hundreds of bases to the Iraqis. And we have moved millions of pieces of equipment out of Iraq.

"This completes a transition to Iraqi responsibility for their own security. U.S. troops pulled out of Iraq's cities last summer, and Iraqi forces have moved into the lead with considerable skill and commitment to their fellow citizens. Even as Iraq continues to suffer terrorist attacks, security incidents have been near the lowest on record since the war began. And Iraqi forces have taken the fight to al Qaeda, removing much of its leadership in Iraqi-led operations.

"This year also saw Iraq hold credible elections that drew a strong turnout. A caretaker administration is in place as Iraqis form a government based on the results of that election. Tonight, I encourage Iraq's leaders to move forward with a sense of urgency to form an inclusive government that is just, representative, and accountable to the Iraqi people. And when that government is in place, there should be no doubt: the Iraqi people will have a strong partner in the United States. Our combat mission is ending, but our commitment to Iraq's future is not.

"Going forward, a transitional force of U.S. troops will remain in Iraq with a different mission: advising and assisting Iraq's Security Forces; supporting Iraqi troops in targeted counter-terrorism missions; and protecting our civilians. Consistent with our agreement with the Iraqi government, all U.S. troops will leave by the end of next year. As our military draws down, our dedicated civilians - diplomats, aid workers, and advisors - are moving into the lead to support Iraq as it strengthens its government, resolves political disputes, resettles those displaced by war, and builds ties with the region and the world. And that is a message that Vice President Biden is delivering to the Iraqi people through his visit there today.

"This new approach reflects our long-term partnership with Iraq-one based upon mutual interests, and mutual respect. Of course, violence will not end with our combat mission. Extremists will continue to set off bombs, attack Iraqi civilians and try to spark sectarian strife. But ultimately, these terrorists will fail to achieve their goals. Iraqis are a proud people. They have rejected sectarian war, and they have no interest in endless destruction. They understand that, in the end, only Iraqis can resolve their differences and police their streets. Only Iraqis can build a democracy within their borders. What America can do, and will do, is provide support for the Iraqi people as both a friend and a partner.

"Ending this war is not only in Iraq's interest - it is in our own. The United States has paid a huge price to put the future of Iraq in the hands of its people. We have sent our young men and women to make enormous sacrifices in Iraq, and spent vast resources abroad at a time of tight budgets at home. We have persevered because of a belief we share with the Iraqi people - a belief that out of the ashes of war, a new beginning could be born in this cradle of civilization. Through this remarkable chapter in the history of the United States and Iraq, we have met our responsibility. Now, it is time to turn the page.

"As we do, I am mindful that the Iraq War has been a contentious issue at home. Here, too, it is time to turn the page. This afternoon, I spoke to former President George W. Bush. It's well known that he and I disagreed about the war from its outset. Yet no one could doubt President Bush's support for our troops, or his love of country and commitment to our security. As I have said, there were patriots who supported this war, and patriots who opposed it. And all of us are united in appreciation for our servicemen and women, and our hope for Iraq's future.

"The greatness of our democracy is grounded in our ability to move beyond our differences, and to learn from our experience as we confront the many challenges ahead. And no challenge is more essential to our security than our fight against al Qaeda.
