Establishing democracy at the heart of the Middle East no longer qualifies, desirable as that would be. Where Mr. Bush sees an infant secular Iraqi government, most of the world sees a collection of ethnic and religious factional leaders, armed with private militias, presiding over growing strife between Shiites and Sunnis. Warning that American withdrawal would "embolden" the enemy is far from an argument as long as there is constant evidence that American presence is creating a fearful backlash throughout the Muslim world that empowers the fanatics far more than it frightens them.

Fending off the chaos that would almost certainly come with civil war would be a reason to stay the course, although it does not inspire the full-throated rhetoric about freedom that Mr. Bush offered last night. But the nation needs to hear a workable plan to stabilize a fractured, disintegrating country and end the violence. If such a strategy exists, it seems unlikely that Mr. Bush could see it through the filter of his fantasies.

It's hard to figure out how to build consensus when the men in charge embrace a series of myths. Vice President Dick Cheney suggested last weekend that the White House is even more delusional than Mr. Bush's rhetoric suggests. The vice president volunteered to NBC's Tim Russert that not only was the Iraq invasion the right thing to do, "if we had it to do over again, we'd do exactly the same thing."
