A damn good question for everyone on the anti-war side, not just the "miracle the troops home today" people. Withdrawing from Iraq is going to be a huge project in and of itself. It will require long-term planning, coordination, all the stuff the Bush administration can't do worth a damn. Even with competent management it's likely to be a disaster.

Everyone is talking about whether the United States should withdraw from Iraq. But is anyone actually planning for that day?
...
The central lesson in all these cases was not that withdrawal was a bad idea. Wise or not, it became inevitable. But the aftermath in every case was made worse by the fact that governments waited so long to admit that a pullout might be necessary. When the moment came, their hasty departures made the chaos that followed that much worse.
Think tanks in Washington have begun to explore those consequences for Iraq in detail. Pollack's report, coauthored with Daniel Byman, warns, "When the United States decides that reconstruction has failed and that all-out civil war in Iraq has broken out, the only rational course of action, horrific though it will be, is to abandon Iraq's population centers and refocus American efforts from preventing civil war to containing it." Many of the paper's broad recommendations are similar to those made by the Iraq Study Group chaired by former secretary of State James Baker and former congressman Lee Hamilton last fall: work for regional peace and stability. Others are draconian suggestions tied to fears of disastrous events—for instance, to create a system of "buffer zones" to collect refugees at the borders.

Ultimately, even informal discussions of fallback options keep coming to the same conclusion: U.S. troops will have to stay in Iraq—perhaps not in combat roles, but in large numbers nonetheless. Philip Zelikow, who formerly worked with Secretary of State Condoleezza Rice, notes that the kind of "drawdown" being proposed by the Democrats "is easy to say, but the issue is, what are you going to withdraw?" The U.S. forces are vital to the Iraqi military's logistics and intelligence, and also act as a restraint. If the Americans pull back, the Iraqis "will end up fighting the war their way," says Zelikow, and that would be uglier than the conflict we have now.
Even Steven Simon, who strongly advocates disengagement, says that American and other international forces—once they pull out of Iraq—should be ready to go back in "for humanitarian intervention in the event that violence in Iraq becomes genocidal."
The day after in Iraq may look a lot like the day before.
