This war is more than a clash of arms--it is a decisive ideological struggle, and the security of our nation is in the balance. To prevail, we must remove the conditions that inspire blind hatred, and drove 19 men to get onto airplanes and to come and kill us. What every terrorist fears most is human freedom--societies where men and women make their own choices, answer to their own conscience, and live by their hopes instead of their resentments. Free people are not drawn to violent and malignant ideologies--and most will choose a better way when they’re given a chance. So we advance our own security interests by helping moderates and reformers and brave voices for democracy. The great question of our day is whether America will help men and women in the Middle East to build free societies and share in the rights of all humanity. And I say, for the sake of our own security, we must. (Applause.)

In the last two years, we’ve seen the desire for liberty in the broader Middle East--and we have been sobered by the enemy’s fierce reaction. In 2005, the world watched as the citizens of Lebanon raised the banner of the Cedar Revolution, they drove out the Syrian occupiers and chose new leaders in free elections. In 2005, the people of Afghanistan defied the terrorists and elected a democratic legislature. And in 2005, the Iraqi people held three national elections, choosing a transitional government, adopting the most progressive, democratic constitution in the Arab world, and then electing a government under that constitution. Despite endless threats from the killers in their midst, nearly 12 million Iraqi citizens came out to vote in a show of hope and solidarity that we should never forget. (Applause.)

A thinking enemy watched all of these scenes, adjusted their tactics, and in 2006 they struck back. In Lebanon, assassins took the life of Pierre Gemayel, a prominent participant in the Cedar Revolution. Hezbollah terrorists, with support from Syria and Iran, sowed conflict in the region and are seeking to undermine Lebanon’s legitimately elected government. In Afghanistan, Taliban and al Qaeda fighters tried to regain power by regrouping and engaging Afghan and NATO forces. In Iraq, al Qaeda and other Sunni extremists blew up one of the most sacred places in Shia Islam--the Golden Mosque of Samarra. This atrocity, directed at a Muslim house of prayer, was designed to provoke retaliation from Iraqi Shia--and it succeeded. Radical Shia elements, some of whom receive support from Iran, formed death squads. The result was a tragic escalation of sectarian rage and reprisal that continues to this day.

This is not the fight we entered in Iraq, but it is the fight we’re in. Every one of us wishes this war were over and won. Yet it would not be like us to leave our promises unkept, our friends abandoned, and our own security at risk. (Applause.) Ladies and gentlemen: On this day, at this hour, it is still within our power to shape the outcome of this battle. Let us find our resolve, and turn events toward victory. (Applause.)

We’re carrying out a new strategy in Iraq--a plan that demands more from Iraq’s elected government, and gives our forces in Iraq the reinforcements they need to complete their mission. Our goal is a democratic Iraq that upholds the rule of law, respects the rights of its people, provides them security, and is an ally in the war on terror.

In order to make progress toward this goal, the Iraqi government must stop the sectarian violence in its capital. But the Iraqis are not yet ready to do this on their own. So we’re deploying reinforcements of more than 20,000 additional soldiers and Marines to Iraq. The vast majority will go to Baghdad, where they will help Iraqi forces to clear and secure neighborhoods, and serve as advisers embedded in Iraqi Army units. With Iraqis in the lead, our forces will help secure the city by chasing down the terrorists, insurgents, and the roaming death squads. And in Anbar Province, where al Qaeda terrorists have gathered and local forces have begun showing a willingness to fight them, we’re sending an additional 4,000 United States Marines, with orders to find the terrorists and clear them out. (Applause.) We didn’t drive al Qaeda out of their safe haven in Afghanistan only to let them set up a new safe haven in a free Iraq.

The people of Iraq want to live in peace, and now it’s time for their government to act. Iraq’s leaders know that our commitment is not open-ended. They have promised to deploy more of their own troops to secure Baghdad--and they must do so. They pledged that they will confront violent radicals of any faction or political party--and they need to follow through, and lift needless restrictions on Iraqi and coalition forces, so these troops can achieve their mission of bringing security to all of the people of Baghdad. Iraq’s leaders have committed themselves to a series of benchmarks--to achieve reconciliation, to share oil revenues among all of Iraq’s citizens, to put the wealth of Iraq into the rebuilding of Iraq, to allow more Iraqis to re-enter their nation’s civic life, to hold local elections, and to take responsibility for security in every Iraqi province. But for all of this to happen, Baghdad must be secure. And our plan will help the Iraqi government take back its capital and make good on its commitments.

My fellow citizens, our military commanders and I have carefully weighed the options. We discussed every possible approach. In the end, I chose this course of action because it provides the best chance for success. Many in this chamber understand that America must not fail in Iraq, because you understand that the consequences of failure would be grievous and far-reaching.

If American forces step back before Baghdad is secure, the Iraqi government would be overrun by extremists on all sides. We could expect an epic battle between Shia extremists backed by Iran, and Sunni extremists aided by al Qaeda and supporters of the old regime. A contagion of violence could spill out across the country--and in time, the entire region could be drawn into the conflict.

For America, this is a nightmare scenario. For the enemy, this is the objective. Chaos is the greatest ally--their greatest ally in this struggle. And out of chaos in Iraq would emerge an emboldened enemy with new safe havens, new recruits, new resources, and an even greater determination to harm America. To allow this to happen would be to ignore the lessons of September the 11th and invite tragedy. Ladies and gentlemen, nothing is more important at this moment in our history than for America to succeed in the Middle East, to succeed in Iraq and to spare the American people from this danger. (Applause.)
