The murderous ideology of the Islamic radicals is the great challenge of our new century. Yet in many ways, this fight resembles the struggle against communism in the last century. Like the ideology of communism, Islamic radicalism is elitist, led by a self-appointed vanguard that presumes to speak for the Muslim masses. Bin Laden says his own role is to tell Muslims, "what is good for them and what is not." And what this man who grew up in wealth and privilege considers good for poor Muslims is that they become killers and suicide bombers. He assures them that this road - that this is the road to paradise - though he never offers to go along for the ride. (Applause.)

These militants are not just the enemies of America or the enemies of Iraq, they are the enemies of Islam and they are the enemies of humanity. And we have seen this kind of shameless cruelty before - in the heartless zealotry that led to the gulags, the Cultural Revolution, and the killing fields.

And our debate at home must also be fair-minded. One of the hallmarks of a free society and what makes our country strong is that our political leaders can discuss their differences openly, even in times of war. When I made the decision to remove Saddam Hussein from power, Congress approved it with strong bipartisan support. I also recognize that some of our fellow citizens and elected officials didn't support the liberation of Iraq. And that is their right, and I respect it. As President and Commander-in-Chief, I accept the responsibilities, and the criticisms, and the consequences that come with such a solemn decision.

While it's perfectly legitimate to criticize my decision or the conduct of the war, it is deeply irresponsible to rewrite the history of how that war began. (Applause.) Some Democrats and anti-war critics are now claiming we manipulated the intelligence and misled the American people about why we went to war. These critics are fully aware that a bipartisan Senate investigation found no evidence of political pressure to change the intelligence community's judgments related to Iraq's weapons programs.

They also know that intelligence agencies from around the world agreed with our assessment of Saddam Hussein. They know the United Nations passed more than a dozen resolutions citing his development and possession of weapons of mass destruction. And many of these critics supported my opponent during the last election, who explained his position to support the resolution in the Congress this way: "When I vote to give the President of the United States the authority to use force, if necessary, to disarm Saddam Hussein, it is because I believe that a deadly arsenal of weapons of mass destruction in his hands is a threat, and a grave threat, to our security." That's why more than a hundred Democrats in the House and the Senate - who had access to the same intelligence -- voted to support removing Saddam Hussein from power. (Applause.)

The stakes in the global war on terror are too high, and the national interest is too important, for politicians to throw out false charges. (Applause.) These baseless attacks send the wrong signal to our troops and to an enemy that is questioning America's will. As our troops fight a ruthless enemy determined to destroy our way of life, they deserve to know that their elected leaders who voted to send them to war continue to stand behind them. (Applause.) Our troops deserve to know that this support will remain firm when the going gets tough. (Applause.) And our troops deserve to know that whatever our differences in Washington, our will is strong, our nation is united, and we will settle for nothing less than victory. (Applause.)
