Despite the mounting death toll and the growing public dissatisfaction with the war, Bush said that the United States is making steady progress by killing enemy fighters, training Iraqi troops and guiding Iraq toward democracy. He cautioned that ultimate victory in Iraq -- which he called the central front in the global war on terrorism -- will come only with patience, determination and continued sacrifice.

"This war will require more sacrifice, more time and more resolve," he said in a speech hosted by military spouses at Bolling Air Force Base. "No one should underestimate the difficulties ahead, nor should they overlook the advantages we bring to this fight."
