In the mind of the terrorist, this war began well before September the 11th, and will not end until their radical vision is fulfilled. And these past five years have given us a much clearer view of the nature of this enemy. Al Qaeda and its followers are Sunni extremists, possessed by hatred and commanded by a harsh and narrow ideology. Take almost any principle of civilization, and their goal is the opposite. They preach with threats, instruct with bullets and bombs, and promise paradise for the murder of the innocent.

Our enemies are quite explicit about their intentions. They want to overthrow moderate governments, and establish safe havens from which to plan and carry out new attacks on our country. By killing and terrorizing Americans, they want to force our country to retreat from the world and abandon the cause of liberty. They would then be free to impose their will and spread their totalitarian ideology. Listen to this warning from the late terrorist Zarqawi: "We will sacrifice our blood and bodies to put an end to your dreams, and what is coming is even worse." Osama bin Laden declared: "Death is better than living on this Earth with the unbelievers among us."

These men are not given to idle words, and they are just one camp in the Islamist radical movement. In recent times, it has also become clear that we face an escalating danger from Shia extremists who are just as hostile to America, and are also determined to dominate the Middle East. Many are known to take direction from the regime in Iran, which is funding and arming terrorists like Hezbollah -- a group second only to al Qaeda in the American lives it has taken.

The Shia and Sunni extremists are different faces of the same totalitarian threat. Whatever slogans they chant, when they slaughter the innocent they have the same wicked purposes. They want to kill Americans, kill democracy in the Middle East, and gain the weapons to kill on an even more horrific scale.

In the sixth year since our nation was attacked, I wish I could report to you that the dangers had ended. They have not. And so it remains the policy of this government to use every lawful and proper tool of intelligence, diplomacy, law enforcement, and military action to do our duty, to find these enemies, and to protect the American people. (Applause.)

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.)
