Our enemies in Iraq have been hit hard. They are not yet defeated, and we can still expect tough fighting ahead. Our objective in the coming year is to sustain and build on the gains we made in 2007, while transitioning to the next phase of our strategy. American troops are shifting from leading operations to partnering with Iraqi forces and, eventually, to a protective overwatch mission. As part of this transition, one Army brigade combat team and one Marine Expeditionary Unit have already come home and will not be replaced. In the coming months, four additional brigades and two Marine battalions will follow suit. Taken together, this means more than 20,000 of our troops are coming home.

Any further — any further drawdown of U.S. troops will be based on conditions in Iraq and the recommendations of our commanders. General Petraeus has warned that too fast a drawdown could result in, quote, “the disintegration of the Iraqi security forces, Al Qaeda-Iraq regaining lost ground, and a marked increase in violence.”

Members of Congress, having come so far and achieved so much, we must not allow this to happen.
