Loved the emphatic delivery too:
We have more work to do, and there will be tough moments that test America’s resolve. We are fighting against men with blind hatred–and armed with lethal weapons–who are capable of any atrocity. They wear no uniform; they respect no laws of warfare or morality. They take innocent lives to create chaos for the cameras. They are trying to shake our will in Iraq–just as they tried to shake our will on September 11, 2001. They will fail. The terrorists do not understand America. The American people do not falter under threat–and we will not allow our future to be determined by car bombers and assassins.
