In Iraq, the terrorists and extremists are fighting to deny a proud people their liberty and fighting to establish safe havens for attacks across the world. One year ago, our enemies were succeeding in their efforts to plunge Iraq into chaos. So we reviewed our strategy and changed course. We launched a surge of American forces into Iraq. We gave our troops a new mission: Work with the Iraqi forces to protect the Iraqi people; pursue the enemy in its strongholds; and deny the terrorists sanctuary anywhere in the country.
