The Democrats are demanding, without any preconditions on the ground in Iraq, that the United States leave the battlefield during an active war.

You can dress it up any way you like, and Lord knows the Democrats have been good at euphemisms for "cut and run," but the entire planet will treat a "redeployment" as an abject defeat for the U.S. and an enormous victory for those we are fighting over there.

You can work out for yourself what the results would be around the world.

Because of the importance of Iraq, the potential for catastrophe, and the role and commitments of the United States in initiating events that have led to the current situation, we believe it would be wrong for the United States to abandon the country through a precipitate withdrawal of troops and support. A premature American departure from Iraq would almost certainly produce greater sectarian violence and further deterioration of conditions, leading to a number of the adverse consequences outlined above. The near-term results would be a significant power vacuum, greater human suffering, regional destabilization, and a threat to the global economy. Al Qaeda would depict our withdrawal as a historic victory. If we leave and Iraq descends into chaos, the long-range consequences could eventually require the United States to return.
