"These are vicious people who know no bounds of humanity," Bush said, referring to insurgents in Iraq. "They would not hesitate to murder. It's essential for our citizens to understand this. And that is why this war must be fought and that is why this war, this enemy must be defeated."
Appearing here before a friendly audience of religious-themed broadcasters who greeted the president with a prolonged ovation, Bush also insisted he would not be swayed by the 2008 presidential campaign as he nears a decision on how many troops to leave in Iraq for his successor.
"I want to assure you, just like I assure military families and the troops: The politics of 2008 is not going to enter into my calculation. It is the peace of the years to come that will enter into my calculation," Bush said to rousing applause.
