We have long since lost count of all the historic turning points and fast-evaporating victories hyped by this president. The toppling of Saddam's statue, "Mission Accomplished," the transfer of sovereignty and the purple fingers all blur into a hallucinatory loop of delusion. One such red-letter day, some may dimly recall, was the adoption of the previous, interim constitution in March 2004, also proclaimed a "historic milestone" by Mr. Bush. Within a month after that fabulous victory, the insurgency boiled over into the war we have today, taking, among many others, the life of Casey Sheehan.

It's Casey Sheehan's mother, not those haggling in Baghdad's Green Zone, who really changed the landscape in the war this month. Not because of her bumper-sticker politics or the slick left-wing political operatives who have turned her into a circus, but because the original, stubborn fact of her grief brought back the dead the administration had tried for so long to lock out of sight. With a shove from Pat Robertson, her 15 minutes are now up, but even Mr. Robertson's antics revealed buyer's remorse about Iraq; his stated motivation for taking out Hugo Chávez by assassination was to avoid "another $200 billion war" to remove a dictator.

In the wake of Ms. Sheehan's protest, the facts on the ground in America have changed almost everywhere. The president, for one, has been forced to make what for him is the ultimate sacrifice: jettisoning chunks of vacation to defend the war in any bunker he can find in Utah or Idaho. In the first speech of this offensive, he even felt compelled to take the uncharacteristic step of citing the number of American dead in public (though the number was already out of date by at least five casualties by day's end). For the second, the White House recruited its own mom, Tammy Pruett, for the president to showcase as an antidote to Ms. Sheehan. But in a reversion to the president's hide-the-fallen habit, the chosen mother was not one who had lost a child in Iraq.

It isn't just Mr. Bush who is in a tight corner now. Ms. Sheehan's protest was the catalyst for a new national argument about the war that managed to expose both the intellectual bankruptcy of its remaining supporters on the right and the utter bankruptcy of the Democrats who had rubber-stamped this misadventure in the first place.
