To really understand the importance of Maliki's comments, you need to consider their opposite. Imagine if Maliki had walked in front of the cameras and said, "at this stage, a timetable for withdrawal is unrealistic, and we hope our American friends will not bow to domestic political pressures and be hasty in leaving Iraq just as the country improves." It would be a transformative moment in this election. John McCain would talk of nothing else. The cable shows would talk of nothing else. Magazines would run thousands of covers about "Obama's Iraq Problem." Obama would probably lose the race. Instead, the opposite happened. Maliki, speaking to the German magazine Der Spiegel, said, "U.S. presidential candidate Barack Obama talks about 16 months. That, we think, would be the right timeframe for a withdrawal, with the possibility of slight changes." In other words, the head of the Iraqi government endorsed the Obama plan -- both its timetable and its timing -- by name. That's huge. And it's the culmination of a weeks-long effort by the Maliki government to drive their desire for a timetable for withdrawal into the American political conversation. But though they've repeatedly expressed their preference for a timetable for withdrawal, this is the first time they've explicitly supported the plan of one candidate or another. Fundamentally, Maliki's comment is evidence of what the Iraqi government sees as the primary impediment to their government attaining real legitimacy: Us. The American occupation is hugely unpopular, and if Iraq is to truly stabilize, its government needs to be seen as independent from the occupiers and opposed to their continued presence. McCain needs to either come out with a new Iraq plan featuring a withdrawal component tomorrow, or explain why he believes America should fight for continued military dominance in Iraq over the objections of the American people, the Iraqi people, and the Iraqi government.
